Most of my pistol shooting is from 7-25 yards, but I like to shoot at 100 + yards just for fun. Even with my 642 pocket pistol. You shoot at 100 yards with a 2 inch pistol, you may not hit much but it helps your 7 yard shooting.
You'd be supprised with a little practice how you could get to where you could discourage bad behavier at 100 yards.
