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 was the end-result of a series of developments by famous gun designer John Browning, starting with the Model 1900. The advances made by Browning were revolutionary at the time, and were so successful that they are considered commonplace today. Browning not only developed first a pivoting and then a tilting barrel to allow for a locked system, he developed the concept of “the slide”, which is now synonymous with semi-automatic handguns. Having secured a contract for the US Military sidearm, Colt also offered the pistol to the commercial market as the “Government Model”. 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.

This example has been customized by Craig Wetstein at Auto Shop. Craig is best known for his stint at Pachmayr Custom Shop from 1976-1980 where he was a 1911 gunsmith building custom guns including Combat Specials. The Auto Shop in Culver City was open from 1980-86 and his output was quite low, making this a rare and beautiful piece. Auto Shop guns were very well done and this pistol is proof of that. It has been finished with a beautiful blue and chrome contrast with great mechanics and a crisp trigger with a super short reset. If you’ve got an affinity for 1911 pistols, don’t sleep on this one!
