I've noticed that my gen 3 Glock 19 gets pretty slick during extended range sessions and it's time I do something about it. I've stippled pmags before and I have a pretty good idea about the surfaces on my Glock that need a little more traction. My question is this: Is there anything I need to know about that could catastrophically dick-up my gun? I'm looking for past experience, hindsight notes, or a friend of a friend kind of stuff. any wisdom you can pass on to me that would save me from ruining a $250 dollar frame. Thanks for your time.
