A Bersa 45UC can be had for around $400 used. Those are great guns that are compact and easy to use and take down for cleaning. They are very popular and folks that buy them tend to like them a lot. It's probably the easiest gun to disassemble for cleaning that I've owned. Much easier than a Glock, CZ or 1911. It has a decocker, so condition 1 carry is not possible but for most folks, that's a good thing.
