I have a glock 17 and i am very pleased with it, however, I was wondering what can be done to accurize it. Such as, what would be the better drop in barrel, what else can be done with the trigger besides changing to a 3.5 connecter, can i get a better slide to frame fit and anything else that can be done. My goal with this pistol is a 1 inch shot group at 50 yards. I know this may be unrealistic, but the way I look at it, why stop at "good enough"
