My most often carried traditional double action is a Beretta MiniCougar. Mine started out as DAO, but I added the sear parts, then an extended magazine release & a new set if Spartan night sights. It holds 8+1rounds of .40S&W or 357Sig, depending on which barrel I have in it. Or I can use the 10round mag shown in this picture. I carry a 13rd modified MecGar Beretta 96 mag as backup.
My 2nd favorite carry gun is a Beretta 96G Centurion.
