You have probably already set your mind, but if you are still looking, for reliability, I would recommend looking at a used Smith and Wesson revolver. You can pick up a police trade in model 10 from buds gun shop for 269.99 which is a .38 special. Or if you can find one in your area, a used model 36 with a 1 7/8" barrel or 3" if you would rather, they make great carry guns. I really like all of the older Smith and Wessons. Or if you are looking more at a semi auto, one of the steel framed autos are great, I picked up a model 39-2, which is a 8 round 9mm with 5 mags for 300 dollars. And it is a sweet shooter! Anyways, enjoy whichever route you go!
