I was working for a small shop in Flagstaff Arizona when the first Glocks started to arrive in 1980. First generation Olive Drab color. Wish I had purchased about a dozen of them now. Anyways, all the LEO's were either carrying revolvers or auto loaders at the time. Didn't take long for the Glock's to win out over the revolvers and existing auto loaders of the day. Glock has been at the leading edge of hand gun development for many, many years now, I'm just waiting for them to move into the AR style platforms in a big way just to see what they will come up with against the AR and the H&K competition via law enforcement utility.
