Last one today! Pictured is a 1988 C**t, MarkIV Series 80 Officers ACP chambered in .45ACP. Call Grimm Arms at 304-834-4556 for details. And a little history of course.
Introduced by C**t in 1983, the Mark IV Series 80 was a major evolution of the classic M1911. Its history is defined by the addition of a controversial trigger-actuated firing pin block safety, a new half-cock notch on the sear, and the removal of the problematic Series 70 collet barrel bushing. The defining feature of the Series 80 is its internal mechanical safety plunger. This block prevents the firing pin from striking the primer unless the trigger is pulled, making it much safer to drop or carry fully loaded. C**t replaced the traditional hook-style half-cock with a modern shelf-style notch. On a Series 80, if the trigger is pulled while the hammer is at half-cock, the hammer will safely drop.
