I'm shopping around for my first 1911, need some advice. It will be my first semi-auto handgun besides Ruger P89's, so I'm unfamiliar with field-stripping and such. It will be used mainly for range shooting (no matches or anything) and home defense. I won't be customizing it. I'm looking for a full-sized (5" barrel) gun and my price range is around $600. Any suggestions?
