Tisas has pulled out all of the stops to make the 1911 A1 US Army a dead ringer for the M1911A1. Its chrome-moly-steel frame and slide are finished with a deep Parkerization that has a hint of olive-drab coloration. More importantly, it bears all of the changes made to John Browning’s original design in the early 1920s. This includes a shortened trigger, an arched mainspring housing, scallops on both sides of the frame just behind the trigger, an elongated grip safety and a shortened hammer spur. In a nod to practicality, the Tisas’ ejection port has been lowered a bit, compared to the genuine article, for improved reliability.
