Reading along here made me recall I forgot to mention one of my favorite "odd guns" I have seen a police officer wearing.
When I was a young fellow, it was not uncommon for local policemen to be allowed to keep weapons they had seized and they would sell them for badly needed extra cash. One of the local officers had (of all things) a very nice Model 60 he had obtained permission to keep and sell, and I went down to the police department to meet "Tom" on one of his days off to look at it, with the idea of buying it. In those days, Model 60s were VERY tough to locate.
I walked into the PD and Tom was waiting for me in the lobby. He retrieved the Model 60 from rattling around in a paper bag, that also contained a couple of other handguns (

), and was showing it to me when the Chief walked by. The Chief stopped to admire the Model 60, and then paused for a moment in thought. He told my friend Tom he better cancel the sale and "keep the Model 60 for yourself," considering his present off-duty gun. (It was clear this was an order, not a suggestion.)
I looked down at Tom's belt and he had a "Baby" Browning .25 automatic in a black leather belt holster with a snap-down safety strap. The holster was twice as big as the gun.
So I missed the chance to buy the 60, but heard that several months later the gun went to someone else. Tom thought it was too heavy to carry around when he was not on duty.
This Chief was also one of those Marine types (not an "ex-Marine"

), and he too wore a 1911, but did not carry it loaded. Just kept a loaded mag in the gun and told me there would be time for him to load it if needed - wouldn't take long.
