Ok, I KNOW I am missing something dumb. I have shot a fair number of different handguns but have NEVER once seen a peep sight on a handgun. One of my favorite sight setups is on a buddies 10/22 where he had DUAL peep rings, meaning no post just the two rings. I dont see why this, or a more traditional post and peep setup would not work on a handgun. Is it a problem with the shorter sight radius?
