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 customized Government Model made in 1979. The pistol has been upgraded with a Bo-Mar adjustable rear sight, a target-style front sight, a new trigger with over-travel adjustment as well as a .38 Special Kit barrel. The result is an interesting target pistol which ought to be a great shooter for decades to come
