My go-to handgun: S&W 686 4" pre-zit with hogue grips & meprolight sights.
My fighting handgun: west german Sig 220 with a few 10rd mags full of hot handloads.
I've always been a wheelgun guy by default & would choose any quality .357 if I could only have one. I finally came across the Sig & fell in love with it. First auto that fits my hand & I can hit with.
CZ 75B and Ruger SP101. Love steel firearms over polymer, but I don't carry as of yet. If I started to carry and found the 101 too heavy I would have to trade out the CZ for a small, light semi.
if things got so bad that I could obly have two guns one revolver and one pistol
For a revolver would be my FA 83 454 casull. I can hunt with it if I need to put food on the table and I can down load 45 colts for self defense rounds.
For a pistol My EAA witness 10MM also can hunt with it and use for self defense.
