The .357 SIG. Now THAT'S a gun/round I never had any desire to own.
357 sig is a 357 mag in an auto loader, except with a 12-13 round magazine. A revolver man like you should love that comparison.
I shoot the sig, its more expensive and its accurate. It's also powerful as hell in an auto loader. OHP seems to think it has some mustard too.
Guess to each his own.
