Our Assessment: The Colt MK IV Series 70 Government Model represents one of the most iconic iterations of the classic M1911 pistol, blending the traditional styling of the original Browning design with refinements like the Series 70 collet bushing. This particular example, manufactured in 1979, is finished in brilliant factory nickel and has clearly seen minimal use, remaining in excellent condition overall.
With its sharply checkered walnut grips, crisp slide markings, and original bright finish, this pistol is a collector-grade piece that embodies Colt’s dedication to craftsmanship during this era. The Series 70 pistols are prized by enthusiasts for their cleaner trigger pulls and absence of the later Series 80 firing pin safety components.

The inclusion of the original box—even unlabeled—further cements its desirability for display or investment. Please see our High Quality photos and good luck on your bids.-C.M.
