Smith & Wesson M&P .40 new in case

Smith & Wesson M&P .40 new in case

by Cain

For those interested in looking up more information about my version of the Smith and Wesson M&P 40 via Smith & Wesson’s website, the SKU # for my handgun is 209300. For those of you completely unfamiliar with firearms, I have provided a side view picture at the end of this article for reference labeling most of the features found on the M&P 40. Should reviews for the M&P 9 and M&P 357 make their way onto the website, you will see a lot of overlap in information.

This particular model from Smith & Wesson comes in three calibers, 9mm, .40 S&W, and 357 SIG. So aside from the performance and recoil differences between the three calibers, most of the physical aspects of the M&P 40 are identical to that of the M&P9 and M&P 357. It is no real surprise given the modular design of the M&P handgun line that the factory magazines used by the M&P 40 are stamped for the 357 SIG model as well.

For those of you unfamiliar with firearms or are relatively new to them, the Smith & Wesson M&P handgun model naming convention is based on the caliber that the handgun is chambered in. (M&P 9 = 9mm, M&P 40 = .40 S&W, M&P 45 = .45 ACP, etc.) Since there is hardly any difference in outward appearances between the 9mm, .40 S&W, and .357 SIG models, the top of the barrel is stamped with the caliber used by the handgun.

Smith & Wesson M&P .40 Specs

My M&P 40 came with a carrying case, three 15 round capacity magazines, a user manual, chamber plug, carrying case lock (not shown above) and three interchangeable grip back straps. My particular model of Smith and Wesson M&P 40 is considered a base model as it does not have the optional ambidextrous thumb safety, internal lock, or a magazine lock installed. The one extra I did opt for when I purchased my M&P 40 is the Tritium night sights. I have put close to a thousand rounds down range with the three magazines experiencing no problems.

Ergonomics: If the feel and fit of a handgun in your hand is absolutely paramount, the Smith and Wesson M&P 40, with its superior ergonomics, is sure to grab your attention. The M&P 40 clearly demonstrates why other gun manufacturers should pay attention to the ergonomics of their products.

The releases and levers are large and easy to use. This handgun’s edges are rounded, tapered, and trimmed to present a cleaner looking profile. Straight out of the box, the M&P 40, with its ambidextrous controls, will draw favor from both left-handed or right-handed shooters alike.

The magazine release button comes set for a right-handed shooter, but the manual shows you how to reverse the magazine release to accommodate a left-handed shooter. Because of the ambidextrous nature of the M&P 40, releasing the magazine and reloading this weapon can be done without having to switch hands in the process.

The magazines slide in and out of the M&P 40 without a fuss. Another plus feature is the ability to swap out the back strap with a different size to better fit the grip of the handgun to your hand. Smith & Wesson M&P .40 slideSmith & Wesson’s attention to detail extends beyond the ambidextrous features. The angled wave design grip else on the back of the M&P’s slide is a unique feature I haven’t see really anywhere. This wave design allows for easier opening of the slide should your hands be wet or are wearing gloves.

Smith & Wesson M&P .40 Safety Features

Safety Features: There are two safety features, loaded chamber indicator and integrated trigger safety, that you will find default in all M&P 40 models regardless of the version of M&P that you purchase. The first safety feature is a loaded chamber indicator located behind the caliber stamp on the barrel. The loaded chamber indicator is a hole in the top of the handgun.

If a round is loaded in the chamber you will see the brass or silver-colored rim of the bullet showing when you look down into the indicator. In situations where you find pulling the slide back to check if the handgun is loaded is not feasible (noise discipline), the loaded chamber indicator is a great at-a-glance feature. Smith & Wesson M&P .40 magazine releaseThe second safety feature is the integrated trigger safety.

While I understand the intent of this safety feature, I am of the opinion that an integrated trigger safety ruins a perfectly, good trigger squeeze. Given the choice, I’d much prefer a pairing of a grip safety with an ambidextrous thumb safety (items found on certain types of 1911 handguns like the Taurus P1911) over any integrated trigger safety. I see M&P 40’s integrated trigger safety as the biggest detractor from an otherwise excellent handgun. Smith & Wesson’s trigger safety literally takes up half of the trigger. This safety feature forces the shooter to slide a finger down then in to fire the handgun.

My wife, father-in-law, and I found ourselves hitting the bottom part of the target when we first started out using the Smith & Wesson M&P 40 due to this safety feature. I have had to spend a considerable amount of time learning to compensate for the trigger safety in order to hit targets where I want them. Trigger Pull: The only so-so feature I’ve encountered outside of the trigger safety so far in the M&P 40 design is a trigger pull of 6.5 pounds needed to fire the handgun.

In my opinion, 6.5 pounds is on the high side compared to other polymer frame handguns currently sold on the market. There is a competition trigger that you can buy and install to lower the trigger pull down to 4 pounds, but having to spend the extra money and ripping apart the M&P 40 all for a better trigger may be a detractor to some. Handling & Recoil: The M&P 40 is a very stable platform for the .40 S&W when compared to other brands with its taller profile and how well it fits into a shooter’s hand. Rapid firing 15 rounds from the M&P 40 accurately at a target 25 meters away is very doable I have found.

The M& P40 does share some characteristics common with .40 S&W platform. .40 S&W based polymer frame handguns in general have a top-heavy feel to them and tend to produce a ‘snappy’ recoil that is felt mostly in the wrists. The M&P 40 is no different from others polymer frame handguns in this regard.

My wife complains that the M&P 40 feels like it wants to jump out of her hands when she fires it. Personally, I find the recoil to be acceptable as the direction of the recoil is straight back. If this type of recoil is an issue for some, I’d recommend looking into the M&P 9 instead. Just keep in mind during the last ammunition shortage experienced in the United States, 9 mm was harder to come by than .40 S&W. Ammunition: Do NOT use +P+ (Plus-P-Plus) grade ammunition in this hand gun.

The over pressure created by this type of cartridge will ruin the M&P 40. I have run Winchester, CCI Blazer, and Federal through my M&P 40 without experiencing one misfeed or failure to fire. The M&P 40 handles home defense ammunition like a champ. I heard a while back that Fiocchi 170gr FMJTC (Full Metal Jacket Truncated Cone) rounds had a bad habit of causing M&P 40s problems, but since I do not use ammunition made by Fiocchi I do not view it as an issue. Inside the Smith & Wesson M&P .40Smith & Wesson M&P .40 barrelMaintenance and Lubrication: This is another aspect about the M&P40 that I give high marks for. Unlike traditional construction, the M&P40’s frame only connects to the slide in four places. When fully assembled, you can see a visible gap between the slide and frame.

The advantage of this is fewer places for the carbon to bind up between the frame and slide. In many ways, this can be viewed as a self-cleaning feature as the points of contact scrape out the carbon in each pass. Lubricating the M&P 40 is not overly difficult as there are only 7 points that you need to make sure are lubricated on a regular basis. Glock 23 / M&P 40 comparison: To give everyone a better perspective of the M&P40, I have included a picture of my M&P 40 next to my Glock 23 (also chambered in .40 S&W) for comparing dimensions.

Given that Glock is considered by many to be the most popular handgun manufacturer in the United States, I thought it only proper to use one as a point of reference in this review. The Glock 23 was purchased within one month of my purchase of the M&P 40 and has had the same number of rounds fired from it as the M&P 40 has. Both firearms have night sights installed. The M&P 40 is a larger handgun in comparison to the Glock 23. The M&P 40 is physically longer, a hair wider, heavier, and has a taller profile than that of the Glock. Looking at factory magazines only, the M&P 40 carries 2 more rounds at 15 due to its taller profile. People with wider hands will like the M&P 40’s taller frame better.

Smith & Wesson M&P .40 and Glock 43

Smith & Wesson M&P .40 and Glock

On the surface, both firearms are as accurate as the shooter is. At 25 feet, 50 feet, and 75 feet, there is no real, discernible difference between the two firearms in the terms of accuracy. M&P 40’s .25” longer barrel it isn’t enough length difference to give it a definitive victory over the Glock 23 in long-range shooting. The advantage that M&P 40 has over the Glock 23 is more subtle in nature with the combination of the front and rear sights being farther apart, slightly longer barrel, and an adjustable rear sight.

Even though the recoil generated by each handgun with the same brand of ammo is effectively the same, I have to give M&P 40 the edge since it fits better into the hand than does the Glock 23. As the magazines empty, the force of the recoil is felt more in both models. The Glock 23 is designed for a right-handed shooter as all controls for the handgun are located on the left side. The M&P 40 ambidextrous design and reversible magazine release throws a bone to left-handed shooters. The M&P 40 edges are rounded versus the blocky design favored by Glock.

There is considerable tapering at the front end of the M&P 40 unlike the Glock 23 to allow for easier holstering of the weapon. The slide guard is much more pronounced on the M&P 40 offering better protecting against the slide biting into the meaty part of your hand between your thumb and index finger as the slide moves backwards to eject a spent casing. The M&P 40 is easier to load when your hands are wet with the angled wave design on the back of the slide.

The M&P 40’s ability to swap out the back strap for different hand sizes if superior to that of Glock’s one size fits all approach in the Glock 23. The M& P40s equipment rail is longer and can accommodate a larger range of aftermarket items.

The Glock 23 has a better integrated trigger safety with it being centered in the lower middle of the trigger instead of consuming half of the trigger like the M&P 40’s does. The Glock 23’s integrated trigger safety allows for a more natural trigger squeeze and does not require any modification to a well-practiced trigger squeeze. Disassembling the handguns clearly falls in favor of the M&P 40. The Glock 23 takes a bit more practice to disassemble with its tiny take down levers on both sides of the slide (both have to be engaged at the same time).

The Glock has to be dry fired in order to remove the slide. The M&P 40’s large single take down lever is gentler on smaller hands. Using the frame tool, the M&P 40’s slide can come off without dry firing by pushing down the yellow colored sear deactivation lever in the back of the chamber. People with fat fingers will find trying to get at the lever without the tool frustrating and end up dry firing the M&P 40 like the Glock in order to get the slide off (quicker that way too).



I will admit that I am not a huge fan of polymer frame handguns as I prefer all metal ones like the 1911. It just means the manufacturer of a polymer frame handgun has to try harder to get my attention and win me over. Smith & Wesson M&P 40’s inexpensive price tag, quality, rugged reliability, and ergonomics are major reasons as to why I bought mine. There are a couple of issues that I have with the M&P40, but overall, the M&P40 handgun is a worthy addition to anyone’s collection. The anatomy of the M&P 40: Additional Review of the M&P 40: Jeff Quinn has a review on the M&P 40 worth a read. – Disclaimer: I have no vested interested (financial or otherwise) in either Glock or Smith & Wesson outside of owning several of their products.


  1. JP in MT says:

    I know two new pistol owners that have M&P 40’s, and both like the gun. It does have an advantage over the Glock in price (up to $100 cheaper) and comes with 3 mags instead of 2 (another $20+ savings).

    I would like to try an S&W9 if one shows up at a gun show that someone is not extremely proud of.

  2. Thank you very much for this well-written review. I can shoot and very well, but there are sooooo many different brands, sizes, calipers etc. that make my head spin! Although I don’t own a handgun, yet, I am now familiar (and very thoroughly, I may add!) with two. Good job.

  3. Nice review and if you like semi auto handguns then you should surely look at this one since I am a big fan of Smith and Wesson Handguns.
    That said, since I am a revolver person, trigger safeties, magazine releases etc are not a problem for me. Basic difference as I see it is in gun cartridge capacity. You have a 15 round magazine and I can only hold six in my cylinder, but then again, I don’t plan on needing more than two at the most to do the job. Again like I said, a nice review.

    • SurvivorDan says:

      I too love revolvers. And while a pair of RG .38 specials served my well during some unpleasantness in the 70s, I would point out that the typical successful civilian self defense with a handgun involved three rounds. So you’re still ok there. Only half empty.
      But in one gunfight as an LEO, I expended 43 rounds (unusual, granted) against a single assailant. Mock my lack of shooting prowess but I assure you that I often {when no one is shooting at me!} shoot 250/250s – no misses. He was a quick, aggressive and well armed bastard.
      In yearly electronic simulations with one or more assailants I averaged 7-8 rounds expended to a successful conclusion. I began my LEO work with the GP 100 – 6 rounds. Not good. Switched to the 15 + 1 capacity of the Glock 19.

      When I do choose to carry a revolver, I carry two revolvers, giving me 10 to 12 rounds without reloading. Of course, speed loaders and a belt mounted tac loader are de rigueur.

      With that warning about rounds expended, I love the reliability of a revolver and simplicity of the manual of arms of such and many can be hot loaded with little danger (thinking Ruger and S&W revolvers). Latest revolver is my Ruger BlackHawk in 45 LC. Fine trail gun and when empty, I can beat the hell out of somebody or some critter with it in exigent circumstances. 😉

      • recoveringidiot says:

        Not meaning to pry into something you don’t want to talk about and ignore this if you want, I have a question about that long shoot out you were involved in. The few times I have had to react to what I considered a life threatening situation my adrenalin levels were off the chart and afterward I could hardly stand much less function to any degree. How did you keep going for 40+ rounds? I understand that training is everything but that episode must have been more like a small war than than the typical LEO shoot. I’m not sure that I would stroke out afterward if not during something like that. I for one am glad you are still with us.

        • SurvivorDan says:

          While ago and I was doing more spray-to-keep-em-away than good shot placement though I took the opportunity when I could. And you are right despite some experience I did freak out a little at the finish. Have expended many more rounds in the service of Uncle Sam. You just keep going ’til the end. Then the adrenaline dumb and the ‘rush’ hits you. Always a terrifying experience.
          Of course that was a very unusual non-combat situation. But I merely wanted to emphasize that a single revolver can be woefully inadequate especially with well armed or multiple assailants.
          Harold sounds confident and I probably wouldn’t want him to put a couple of rounds downrange at me with his revolver! And I love my SP101s. But if I carry them, I always carry both with reloads. ‘Nuff said.

          • SurvivorDan says:

            …adrenaline ‘dump’….

            • Adrenaline is a wonderful enzyme and it’s effects can be controlled somewhat. As a kid, I would often get mad and “see red” as they called it back than and sometimes my actions became uncontrollable. By the time I had reached fourteen, I had been knocked around enough by an abusive father that I could better control my adrenaline surges. Close combat training in the Army by a really good instructor who not only taught the moves but also how to control your thinking and emotions. He taught us through experience to just get mad or scared enough to start the adrenaline flow but to then clamp down on it before we got to the point of seeing red. He said you needed the extra energy the adrenaline dump gave you to not only give you the strength to throw someone hard, but to also keep you going long enough to kick them in the nuts to keep them down. As we progressed in the training (13 weeks) we also noticed that the adrenaline let down was not as extreme and we did not get the shakes or nearly pass out like we did when we first started. It was a wonderful part of the training that I have successfully used throughout my life so far. I am just glad that I had an instructor who knew what he was doing and unlike some of the other students, I enjoyed every moment of it even though it was such a long course. I still don’t know what they were preparing us for since most of the courses only lasted a couple of weeks, but eight of us were chosen for this one. Never have seen that type of instruction offered anywhere else and I have never had to ram my stiffened fingers through a persons ribcage and jerk out a rib or two like they taught us during the course. I think mostly they only teach defensive moves now and not the offensive and defensive regimen we were taught then.

          • I hope you realize of course, that since I am still alive that I came out the winner. I did use speedloaders which to be honest, work a lot better with the short S&W38 case than they do with the 38 special or 357 Magnum. We did not have much choice, either purchase and carry two speedloaders on our belt or go to the automatic. The only prolonged shootout and only the third one I encountered in my short career was decided by a 9mm. It was an old war trophy Schmeisser sub machine gun that was supposed to have been deactivated but the bolt they had jammed in the bore came out so the owner, rather than go through a lot of paper work, donated it to the police department. 32 round magazine of which 20 was the most I ever expended at one time settles most arguments in a hurry. Incident was a 10 ton dump truck loaded with freshly harvested hemp that the persons did not want to surrender. I was a special deputy for the small county which only had two full time deputies and all of us local town cops were sworn in as special deputies. I had received a radio call from an IBI car to stop this particular truck and hold it until help arrived at and intersection nine miles removed from my town. Stop was successful, but they failed to tell me what the truck contained and that the people were probably armed and would resist. The scum put a couple of bullet holes in my new (to me at least since it was a hand me down from the state police) patrol car. This disturbed me to the point that I had to return fire and after the third round, one of the perps decided not to chance it and came out of the truck and went face down with hands on head in the approved manner. Other creep sneaked out the other side and was leaning around the front and popped another shot at me. I had just reached back in the car to grab the Schmeisser when he done this. I could see his legs from under the truck so I put a burst in his legs a that stopped all resistance. I had just gotten done binding their hands with the plastic tie wraps when not only the IBI, but also the patrol deputy, the local cop from the next town over from me and the state police all arrived. I still believe they done it on purpose. The IBI took over and I was cautioned not to talk about it at that time. Since 40 years have went by I don’t think they will bust me for spilling the beans now. During WWII the local farmers were encouraged to plant the drainage ditch banks with hemp because the Japanese had seized the territory that we got the hemp from and they needed it for the war effort. I don’t think they ever got it totally eradicated. As a matter of fact, Jim Stafford sang a country song called the wildwood weed which refers to this particular nuisance as then now call it. Never tried it so it is just hearsay.

        • Jarhead 03 says:

          Recovering, when I came back from Somalia and started teaching at the School of Infantry we started a program to simulate the adrenaline factor and we learned about it talking to some of the “operators” that were there in Somalia with us from the Army and Navy as well as our Force Recon.

          We would start of with a simulated patrol and then yell drop and full combat gear start doing push ups, leg lifts, flutter kicks, jumping jacks (side straddle hops) and a sprint to the firing line and have them fire on their targets. The elevated heart rate and blood flowing was as close to the adrenaline factor so they could see how firing in that condition affects the shooters ability to accurately put rounds down range. It became an SOP in training so that when later down the road they ended up in Afghan and Iraq they were a bit more accustomed to the adrenaline factor.

          Till this day, I have not met a high that comes close as the first firefight. I have had injuries while it was flowing that I didn’t feel until hours later or the next day.

          Coming down off of it is hard that’s for sure.

  4. Lee (tx) says:

    Good review, good pistol,,, one point though: .40 +p is nothing more than a marketing gimmic. All S&W 40 is loaded to 35,000 pressure. If any ammo manufacturing company actually loaded ammo to more than SAAMI spec’s it would open them to all kinds of liability law suits. Of course, if some hand loader wanted to ecceed SAAMI spec’s then yes, the firearm will be damaged, but that is true with any cartridge.

    • Lee (tx) says:

      And any firearm, that was what the review was covering.

    • JP in MT says:

      Actually the 40 S&W +P would be a 10mm. The 10mm was the parent cartridge of the 40, less pressure and recoil at the request of Law Enforcement.

      • Lee (tx) says:

        but then it would be labled 10mm, not S&W 40, correct?, there is no difference in “regular 40 and +p40,,,, do not pay more believing you are getting a “hotter” round,,, of course the bullet type might justify a higher cost.

        • Legion7 says:

          I am a 10mm fan, and as such call the .40sw a “10mm short” with a smile. I carry .40sw for every day use, as it’s a bit more defensible in court if it ever comes to it. That being said, I own BOTH a glock 22 and an M&P .40, and my every day choice is the M&P. The ergonomics are superior to everything I own, and my personal back strap for it is a crimson trace laser setup. I’ve never had an issue with either pistol, but the M&P is ergonomically superior.

          • Jarhead 03 says:

            Legion, agreed. I nearly bought a S&W 1006 and fell in love with its accuracy but I hit 21 and it was getting harder to find them and with ammo costs of the 10mm round and the new .40 on the market I picked up the Glock 22 instead. I wish it had a stronger following so I could invest in one when buying ammo.

  5. SurvivorDan says:

    Great review. Very thorough.
    I rarely take factory trigger pulls down much (except me Ruger SP101s and then only down to a smooth 8 lbs – revolver after all) as in the event of a serious social situation and accompanying prosecution or civil litigation I think the factory pull of 6.5 lbs would be more defensible as I didn’t alter (except maybe make it a little glassier/smoother) it and it was not an negligent discharge. That’s just me.
    All in all you made me want to at least take a look at this weapon. Thanks.

  6. 3gens4wars says:

    I own both pistols discussed. You cant go wrong with either. The 23 better for concealed carry tho. The recoil on the m&p is manageable well enough by my daughter who iwas 10 when she started shootin. Glock is a great gun for ccw or throwin in the truck, the mp40 is a fine full size pistol, up for any task.not sure i agree w the +p ammo comments, mine handles corbons fine & am unaware of ammo any hotter.

  7. 3gens4wars says:

    In general, all the m&p series are outstanding. I have the mp 15 too which works flawlessly

  8. Cold Warrior says:

    There is a reason why the Glock 40’s own the police market in the U.S. and the 9mm Glock’s own the police markets world wide. Price+Performance = Glock.

  9. recoveringidiot says:

    Cain, well written review! I like it when the reviewer actually covers what maintenance they have done, round counts and ammo brands/type. If I were in the market for a pistol of this type your article would make look at the M&P.

  10. I have the M&P40. I like it and agree with the review.

    I previously owned the compact model M&P40C. I found the recoil to be too sharp and the pistol too thick for comfortable concealed carry.

    If you don’t own a .40 this is a good way to add this common caliber to your collection — a quality firearm at a modest price.

  11. Three pictures didn’t make it into the review for one reason or another. Another was cut off by the formatting (I think). Examining the pictures that did make it in, I will make sure the formatting of my next review is set for WordPress.

    I encourage critiques as I am drawing upon them to refine my next review of the M&P15-22.

  12. MENTALMATT says:

    Well in 1992 here in the “D”, we were the first major city to go to the Glock and I have to tell you I was real sceptic. I have to tell you that I fell in love with my Glock 40 Cal. About 2 years ago we went to the M&P 40 cal, and while its cool I still prefer my Glock over it. I Liked the trigger pull better on the Glock and we are having a big issue with the finnish on the M&P rusting. If I had to pick I would go back with Glock. I think the big issue was Glaock would not upgrade our first generation pistols for free and M&P came in and gave up whatever our range instructors wanted.

  13. axelsteve says:

    I was wondering if the 6.5 lb trigger pull was on double action or single action getting the trigger to break?If so the 6.5 lb trigger on single action is excessive in my book.I hate stiff triggers< I do not want to fight the gun.

  14. Ken Rihanek says:

    “The advantage that M&P40 has over the Glock 23 is more subtle in nature with the combination of the front and rear sights being farther apart, slightly longer barrel, and an adjustable rear sight.”

    Aren’t the rear sights on both gun drift adjustable side to side? I didn’t know the M&P had a screw adjustable sight.

    • I do not know many people that have the proper equipment to adjust the sights on any handgun that lacks the screw adjustable sights. Trying to adjust one of these sights with whatever is lying around that looks useful tends do cause damage to the sight being adjusted (lesson learned first hand). The night sights on the Glock 23 do not come with the user friendly, screw adjustable interface.

  15. village idiot says:

    That’s what I call a review, Cain. Very well done. I’m not a huge fan of the plastic guns as most are muzzle light when they are loaded, and I hate that aspect of them. I do have a Glock, my son has an XD, so I’m familiar with them, but I pick up my Kimber or Colt CC 1911 about 99% of the time.

  16. axelsteve says:

    I am also not a fan of poly guns yet.Sometimes it just takes time.Radial tires for example. They had fewer plyes then biased so some people did not trust them at first.Same thing with electronic ignitions and fuel injection.I may get a poly gun some day I just can`t afford to now and would probably stick to good ol steel if I had to buy one any time soon. The article was informative and nice though.

  17. We ( my agency) here in South Florida have been issued M&P 45’s. We are on our second guns as the originals were all replaced and the second set of magazines and now new springs. The rusting of the gun was horrendous. The first (and last) I had was so inaccurate that our range master said the only way to fix it was to put a new gun under the sights. We have numerous failure to feeds and fires as well pins coming lose from the frame. These were not seldom issue they were with in most of the above all the guns. They replaced them for free.
    The trigger reset is not smooth and easily felt as it is with other weapons. Having to reach into a locked back slide to flip the slide release has bit a couple of fingers on some people. I truly like Smith&Wesson but this one I personally stay away from. The new models have not had the problems of the originals we were issued but I now “gun shy” about this one. We were carrying Glock 22’s and I now carry a Glock 21 . I purchased it instead of carrying their gun which they give you when you retire.

    Just my 2 cents…….

  18. @axelsteve, you correct it is double action. which would (imho)constitute another safety feature as it means(for those who don’t know…which now that I think about probably isn’t anyone here) that it’s not fully cocked even when chambered and ready to fire. if the striker is released at this “almost fully cocked” point it’s not supposed to have enough force to set off the primer, so theoretically even if you drop it and the striker releases it shouldn’t be able to discharge. pulling the trigger actually pushes the striker back to complete the full cocking and then releases it, only then allowing it to discharge. although, I’m no hurry to prove it works…..

    also, I’m kind of surprised at rowdy’s experience. the slide, barrel, and part of the frame are stainless, I wouldn’t think that it would have a rust problem. though I’ll admit, I’m in missouri not south florida, and that’s never been much of an issue here. I think the trigger smoothness you’re experiencing may be a consequence of the double action safety, or trigger safety, or both, and I have experienced some feed problems as well, so I doubt any of that at least is due to the rust.

    I could be completely wrong the but I think the feed problems are due to the shape of the chamber guide. anytime I have a feed jam(not that often) that’s always what it’s caught on(not a huge deal, since a slight tug on the slide is all it takes for it to go home), and I think it might be too steep, or perhaps not dished enough. of course the nature of your feed problems could be totally different as well.

  19. the S&W M&P 40 is 3 guns in one all you have to do is change the barrell and in the 9mm case get a 9mm magazine otherwise 3 guns in 1 i got all 3 barrells and both mags a lazer have had no ftf or fte esisodes whatsoever. it simply is an awsome pistol that all of american leo should be carrying. being its made in america.

  21. Origin of the 40. just out of interest I have read that the FBI had a shootout that lasted ages because of low stopping power of 9mm. They wanted a more powerful handgun. Tested 10mm but it had to much recoil for most women and some men. Forget which company came up with 40, which is more than 9mm but less than 10mm. The shoutout involved bad guys with a light calibre semi auto magazine load rifle. He just used suppression fire till he took kill shots. From memory a shotgun blast ended his criminal career.
