I have a 3913 that I have owned for years. I have fired it at the range, but have never carried it. If I were to carry it more, what are some things that I should do to insure its reliability? Or, even to keep as a home defense gun in the nightstand. I bought it used, at a local gun shop, in excellent condition. As far as I know, all the parts are original, recoil spring, etc. Also, is it safe to say that a 3913 will reliably feed any bullet type? Thanks guys.
