I carry my SR1911. I am a reserve officer and had to provide my own weapon. I carried my Glock 17 for a few years and had to provide my own ammo as the department uses Glock 21. The chief at the time said to get a 45 when I got a chance so the ammo would come out of the department. I told him I would, but I wanted to get a gun that I wanted not a Glock 21 to match the rest of the department. He asked what I was thinking and I told him a 1911 and more specifically the ruger SR1911. He said that was fine with him.
Took a while to find one at that time, but it finally came to be.
Old chief went on to become the local sheriff, new chief came in and was not impressed with the 1911 being carried. He was nervous about the cocked and locked situation. Figured I was going to have to go back the Glock 17. Went to the range one day with him and others from the department for some "fun" shooting. The SR1911 got passed around and shot. It was voted the nicest shooting gun that day. It's competition was Glock 21, Berreta 92, HK USP, Glock 17 and Ruger LCP. The chief said carrying it was ok and has been looking for one at a good price for himself.
It has also gotten compliments while walking around events that I was on duty for. Gun people ask about it and give me the nod or thumbs up.
