I've seen this test before. I think it's great. No different than torture tests on knives. It's nice to see what they can take in a pinch.
Chuck Taylor left his under the ocean for 3 months as well as fired it while caked with cow poo, among other things.
Definately a breakthrough in firearms. I doubt that any other can handle anywhere near the abuse and keep running. (Though, I understand Sig comes close.)
I had a Glock 34 9mm that I used to shoot until it was hot, then toss it in a snowbank and watch it sink. Then, I'd shake it off, reload and go again.
I just got a new Glock 20 on Friday. It's my if-I-could-only-own-one-gun gun.
I collect, classic Smith & Wessons because I appreciate finely made firearms. But, when I want a weapon, it's Glock.
