.357 is a hoped up “9” as is .357 Sig and 9x23...
I think I got that figured out.
Some of my samples...
Ruger Vaquero .357 magnum
Ruger Blackhawk .357 magnum
Sig Sauer P232SL 9mm Kurz
Sig Sauer P239TT 9mm parabellum
Sig Sauer P229ST .357 Sig
Sig Sauer P226ST 9mm parabellum
Sig Sauer P220ST .45 Auto
Don't forget the original "hopped up" 9...
