Our Assessment: Colt’s 1911 served the United States military through two World Wars and several other conflicts, is still in use by some units today, and has become popular with law enforcement, competitors, and recreational shooters across the nation. The design has seen some updates including a firing-pin block safety, higher profile sights, and more ergonomic grips, but the basic design and fantastic trigger remain the same after more than a century. Due to its popularity and long life, the 1911 has also been a popular choice for custom pistols, with a wide variety of sights, barrels, parts, and popular modifications. This example is a Commercial Government Model made during a period when some of their finest work was produced. This is a Colt MK IV Series ’70 Government Model from 1973. The descendent of the original Model of 1911, it has updates of the 1911-A1 and this one has been further upgraded with target sights, a King barrel bushing and a wide, serrated trigger shoe. The pistol looks great and has some light wear, but still has a great bore and strong mechanics. Whether you’re looking to add to a Colt collection, want to have a great base for your custom build, or can just appreciate a steel-frame, .45 pistol from the heyday of the 1911, this is a great addition to any safe in America. Please see our photos and good luck!
