I know I'm probably in the minority, but I never really got the never-ending quest for some ultimate, super-duper level of GRIP.
Stippling, skateboard tape, rough grips, Hogue slip on grips, etc, etc.
I shoot a bone-stock Glock 19, and think the grips are fine. I have really small (and usually sweaty) hands, and I wouldn't lose grip on that gun if I had just dipped my hand in Crisco.
Seriously, all of my pistols are pretty easy for me to obtain a solid grip. What am I missing here?
