The Glock is an incredibly reliable pistol and the 9mm version is very pleasant to shoot. I did a recent review on a Glock chambered in 45ACP and that model is at the bottom of my list for 45ACP pistols. At least once a month I practice defensive shooting. I believe in a life threatening situation that you have time to react by pointing and shooting your pistol. If you take the time to aim, it might be a life ending decision. I posted a target that that I did the point and shoot at 27 feet without any warm up shots, so the first few were wide. The target simulates the kill zone. The head shots were from a Ruger American 9mm that I shot for the first time. I will review the Ruger after I take it to the range a few more times. I posted a couple of videos from You Tube. The one is a reliability test, and the other is disassembly, animated video. The Animated video is on a Clock G20, but the assembly and disassembly are the same on all models.
