I think most of it comes from the fact most of us old timers were brought up with 1911s. Glocks feel odd till you've lived with them for many years. Anymore I shoot a glock as well as I shoot anything. Funny thing was I was at the range last year when the local police dept was qualifying. I had a couple 1911s there and none of them ever shot one. they all took there turn and every one of them said it was cool but they just didn't like the right angle grip. All they have shot is glocks. Everyone of them though LOVED the trigger pull.
