This article is going to buy me a lot of hate. I know that delving into this topic is controversial and some of my recommendations will go against the established dogma. I will not only make a recommendation, but give you my reasoning behind it. Perhaps I can save some reader a lot of money, hassle and disappointment. Before you continue reading, I want you to make a decision. I want you to visualize yourself killing another human being. Now visualize a loved one bleeding to death in your arms.
Make a choice which one would you prefer. The purpose of a firearm is to kill another being. Yes, I know, you are supposed to say that you are only trying to stop a threat. I know of no better way to stop a threat than to kill it. If you cannot make that decision now, in relative safety, you will not be able to make that decision in an emergency. The most important decision you must make when using a firearm to defend your life is to pull the trigger.
