I'm not a Glock fan ... the 9 that goes with me on every range trip is my XDm-9 with 4.25 inch barrel ... it fits my hand perfectly with the medium backstrap, very accurate and easy to shoot ... If I'd planned ahead, I'd waited for a shorter barrel and would probably be using it for carry ...
"The gun has been called the great equalizer ... It insures that the people are the equal of their government whenever that government forgets that it is servant and not master of the governed." --Ronald Reagan
