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 one was sent off for some custom work, there is no signature or markings to indicate who did the work, but the pistol is well done. It has a nice new set of sights including a Wichita Arms rear target sight, flat-topped slide, squared and checkered trigger guard, Barsto barrel, and a new duo-tone finish. This is a sharp looking pistol that will be a ton of fun to shoot and even comes with an extra slide and barrel. Please see our photos and good luck!
