Yes, the Glock is an ugly hunk of plastic and metal. Yes, it is ridiculed by some as the "tupperware" pistol. Yes, some people turn their noses down at the thought of a Glock. It's kind of "cool" to be anti-Glock, particularly on gun forums where some regard it as a mark of their knowledge of firearms to "hate the plastic pistol" etc. Others just don't like it because they think it is has, well, a face only a mother would love. There's nothing stylish about a Glock. On the other hand: they do what they are made to do, reliably. They are very easy to maintain. They require little by way of training to learn how to get it to go bang. Some hate that they have no external safety. With a round in the chamber, all you do is pull the trigger and it goes bang and you keep pulling the trigger until the magazine runs out of ammo. That's good, for some, bad for others.
But, frankly, I like Glocks because they have a proven track record of simply working. They just work.
So, without further ado: here is my "Why I Like Glock" video, and, as always, offered respectfully, FWIW, mindful that YMMV.
