When it comes to the defensive carry of a clean, well maintained semi-auto pistol loaded with the high quality factory ammo, the thing that has always bothered me is the number of different ways it can still malfunction on the first magazine, whether or not "user error" is to blame. Most of these do not necessarily involve range training but actual fighting situations. For example: limp wristing while shooting one handed, slide striking a barrier or the shooter or the bad guy grabs it; you accidently bump the magazine release during the hectic situation. This is in addition to the unexplainable jams that tend to occur such as FTF, FTE, failure to go into battery. I've seen them over and over again. I've seen a Glock jam up using factory ammo and it took the firearms instructor shooting it about thirty seconds to clear it. A couple of years ago, I searched the web for instances where a police officer's semi- auto malfunctioned in a real life confrontation. I was looking to see what types of circumstances contributed. I stopped at about 40 instances as there is not much information as to the why. It's just accepted as a part of doing business. The key thing is to test the pistol regularly, understand the things that might contribute to the malfunction, and practice malfunction drills until they become second nature. Or, get a good revolver, test it regularly, keep it clean as a whistle, and load it up with the best. I'll bet it will go bang every time, at least for the first cylinder load.
