Anything that suits your shooting ability and your carrying style and the outfit you ware as well. On a daily basis, I may opt for either Walther's TPH .22/.25 ACP or the Beretta 21A .25 ACP as I can have it in my pocket all day without feeling the weight. I also may carry a S&W Mod 442/642 or the Browngin Hungary(similare to Walther PP) in .380 at times if the costume allows but that won't be what I carry daily krub. S &W Mod 15 and Mod 36 3" fulllug by the bedside just in case someone stops by unexpectedly. My Browning Hi-Power 9 MM Para or Springfield 1911 A1 .45 ACP or Colt Goverenemt .38 Super is for the Glove Compartment or when I go into a rough area purposely but don't 100% expecting a gunfight. If I expect a gunfight, then either a Rem M870 or a Benelli Mod 1 with lots of rounds

Sorry for a longwind here but I guess I need to depict the situation a bit to explain what I may carry

cheers..
