If you look at most of the JDC instructors, you’ll see a preponderance of Glocks. At no point will any of us try to tell you that Glocks are perfect, but they do have a good balance of features for the price. In general if somebody asks me “what pistol should I get?” and I don’t have a lot of other information, I’ll probably just knee jerk tell them “Glock 19.” It has enough grip and size to be shootable like a full size gun, yet has enough trimmed off to be an OK concealed carry gun.
I will never try to tell you that Glocks are perfect. Anybody who has worked on or shot a lot of Glocks will be able to tell you the flaws in the design. Obviously the stock sights are awful and must be swapped out immediately for any serious usage. The trigger isn’t great. Many people aren’t fans of the general ergonomics. (Have you ever heard anybody refer to them as a “Block?”) Lastly, you have to press the trigger on the gun to field strip it, and that isn’t very forgiving to somebody who is inattentive.
On the balance, however, are a lot of good characteristics. Glocks are at least reasonably accurate, and the Gen 5 is possibly even more accurate than previous generations. They tend to be quite reliable as long as you use some sort of reasonable ammunition. I also find them to be robust, and able to shrug off casual neglect or even mild abuse. I don’t recommend mistreating any gun that you’re going to bet your life on, but if this happens with a Glock it is likely that it will keep working. You can find parts and accessories for a Glock anywhere. Any gun shop on the planet is likely to have spare parts for you and magazines. At the time of this writing Magpul is making good quality 9mm Glock magazines in varying capacities and the price is right. Every holster vendor on the planet makes Glock holsters. Becoming a Glock armorer takes one 8 hour course, and if you wanted to skip the certification you can certainly learn how to get into the details of the gun online through numerous YouTube videos. I’ll quote Mike Green as saying that “at the end of the world there will be two things left: cockroaches and Glocks.”
For $500-$600 you can buy a Glock. Add $60-$140 for a good set of sights and the gun is ready to go. This leaves most buyers with some extra cash for things like belts, holsters, ammunition, and training. Those final things are the key ingredient in firearms ownership, not just for Glocks.
