I remember when Glock first hit the US market. I was working as a rotation manager between a couple of stores (same company). The Glock rep used to come in towing the pistol behind his car on a rope. Then, we would gather behind the store and he would bury the gun in a bucket of mud and later a bucket of sand. He would then fire the pistol. It worked flawlessly. My 1911 would never do that. I traded in my 45ACP (I was paying attention to science and actual shooting results, not hyperbally and myth) for a 9mm Glock. My father, a space engineer, made fun of my plastic gun (We both carried 1911's in the service) and its puny caliber. One day, out on the little ranch we had, we were behind the dam shooting at some clay targets on the dirt dam. He was doing okay, but shooting all around. The .45acp would hit the mud and dirt and never disturb anything. He noticed when I shot my 9mm dirt and mud flew up in the air. The energy and velocity (people say that doesn't matter, but they are wrong. Ask Weatherby) tore up the ground. He shot my Glock and hit every target dead center. He went down that afternoon and bought a 9mm Glock and carried it everyday until he died decades later, even when working on the ranch. That 9mm never let him down. Feral dogs, coyotes, etc. all showed how effective proper 9mm Parabellum ammunition can be.
