OK, I am looking to make my first gun purchase for my third gun. I have two pistols already, which I inherited after my father passed away. The two I already own are a 1960 production Beretta Model 950B Minx chambered in .22 short semiautomatic and a 1950's-1960's Smith & Wesson Model 31 police issue revolver with the 2" barrel chambered in .32 Long. My primary purpose will be personal protection and concealed carry, and I'd like to semi-retire my dad's guns. I am leaning towards getting either a compact-full sized 9mm semiauto or a .38 special revolver, preferably with a 4in barrel. One of the gun shops in my area has a number of rentals available, and I am looking for recommendations/ other suggestions. I would like to start shooting more for practice, but not many places offer .32 long ammo, and my Beretta, for all its positives, is basically a pea shooter. I want a good middle ground weapon, with reasonably priced ammunition (hence the 9mm and .38 special) but also one I could use for home protection. Any suggestions would be great!
