Cpo sigs seem to have been running 450 to 525 on GB. Used... I just bought a triple stamp 1993 for 450.00 plus shipping. Sent to CCR 200 plus shipping..new parts,new night sights,new srt and grips..plus transfer and sales tax...so 850.00 plus. I kinda got carried away which is easy to do.This message has been edited.
