I have a Colt Gold Cup National Match with Ultimate Bright Stainless finish in .45 acp that I bought new back in the 90’s. It’s a MKIV SERIES 80 with the Elliason adjustable rear sight, a beaver-tail grip safety, and wraparound grips with Colt medallions. It includes the lighter (green) recoil spring and a 7 round magazine for enhanced semi-wadcutter feeding. It also includes an 8 round magazine and heavier recoil spring for use with higher pressure ammunition. The trigger stop is adjustable. I’ve fired a box through the pistol. It is in perfect condition in every respect, inside and out. Serial number is SN10618E. Includes Colt blue case, owners manual, and wrenches for bushing and trigger. I’d like to know the value of this pistol...? Thanks to all.
