I am as guilty as anyone else when it comes to dry firing Glocks. I've always dry fired 100 times the night before and the morning of a match. My assumption was that if you have to dry fire a Glock to field strip it, then it must be OK to dry fire it, period. Well, I've been wrong (again). The official word from Glock is: "If youre going to dry fire onther than for disassembly, use a snap cap." That is a fact and not an invitation for argument. Just accept it for what it's worth. I've just ordered A-Zooms in 9mm and .45GAP from MidwayUSA. Wanna kill these ads? We can help!
