Colt Government Series 80- 45 Cal Stainless Steel NOT AVAILABLE

  • Colt Government Mk. IV Series 80 (1983–present): Introduced an internal firing pin safety and a new half-cock notch on the sear; pulling the trigger on these models while at half-cock will cause the hammer to drop. Models after 1988 returned to the solid barrel bushing due to concerns about breakages of collet bushings.
