I'm looking for a new or used (unaltertered) 357 Sig barrel to drop into my new 229 SAS. MUST be a factory Sig barrel. The aftermarket barrel which functions perfectly in my regular 229 will not fit in the SAS. I have no idea why as all measurements are identical as far as I can tell. Anyway, somebody sell me a factoy barrel in 357 Sig for the 229 and I'll be sane again.
