Mechanics: The action functions correctly. The trigger is crisp. The slide to frame fit has little play. We did not fire this firearm. As with all used firearms, it may need a thorough cleaning to meet your maintenance standards.

Our Assessment: This is a Colt MK IV Series ’70 Government Model from 1980. The descendent of the original Model of 1911, it has updates of the 1911-A1 as well as a collet-style bushing to improve accuracy. The pistol has about 96% of its finish, a bright bore with sharp rifling and strong mechanics. There is a dent in the right of the frame, but it doesn’t appear to affect function. This would make a great recreational shooter, carry, or home defense gun for the 1911 fan. Please see our photos and good luck!
