I have always tried out my service sized handguns at 100yds. When I have mentioned this on this forum and others, I was scoffed at, and there were always those who claimed anything over 7yds was a waste, and "good luck explaining to a jury why you didn't just run away".
Well, I spend some time in the woods, and trusting that an opponent is a bad shot, and running away just does not seem to be very bright.
Shooting a pistol at long range requires sight picture, breathing control, and trigger control, as well as the ability to adopt a solid field position, preferably from cover and concealment.
My carry pistol is a Glock 26. With it, I easily shoot a 10" steel plate at 40yds. When I pick out a point on the 100yd berm, I am hitting right on it.
Still waiting for my Flashback...I would like it now, please.
