Any police trade-in would be a good gun in that price range. These guns were often carried a lot and shot a little. I haven't been on the J&G website lately, but they used to have a lot of ex-cop guns. One of the Eastern European guns, PA-63, Makarov, CZ etc. would be a good gun. I know this is the auto forum, but don't overlook trade-in revolvers either.
