You need a J Frame size 38 Special for concealed carry.
You also need a J Frame size 22LR to practice with.
Then a K Frame in 2", 2-1/2", or 3" for more serious concealed carry.
Then you neee a 4" - 6" K or L Frame 38/357 for general purpose use.

Everyone needs atleast One 1911.
Everyone needs a Ruger MK III to plink with.
Then a Hunting Handgun in 41 Magnum, 44 Magnum, 454, 460 S&W, 480 Ruger, or 500 S&W. I personally love my 480 Ruger Super RedHawks.
You also may need a 10mm/40 S&W Revolver or 40 S&W semi auto to shoot up all the 40 S&W range brass in.
Everyone needs a Barbecue Gun. This should be a Super Clean Blued Steel Smith & Wesson Revolver, Colt Python, or 1911 Colt. Engraving, and or Inlays optional. Super Grips mandatory.
You might reach a point of saturation at some point. Not sure what that number is, I keep finding more handguns that I want. They are also a good investment.
