Historical context
Due to the poor performance of the .38 Long Colt revolvers used in the Philippines during and after the Spanish–American War the US Army sought a new handgun to be chambered in a larger caliber. Tests began in 1907 and culminated in a design from John M. Browning created for the Colt Patent Firearms Manufacturing Co. designated Model 1910, but with changes made to that design. It was type accepted as the Government Model M1911.

Early models
The SIG Sauer GSR ("Granite Series Rail") is a series of pistols with a stainless steel frame and slide based on the Colt M1911 Pistol. The SIG Granite Series was awarded the 2004 Handgun of the Year Award by the Shooting Industry Academy of Excellence. It is entirely made in the USA, from American parts.

Description: Chambered for the .45 ACP round, some GSR models have an accessory rail that can be used to mount a variety of different tactical lights, lasers, or just about anything that can accommodate a Picatinny rail. Standard models have a 5" barrel and 4.5-pound single-action trigger. The GSR is reported to have produced range results of a 1.5" group at 25 meters. The GSR comes in compact (3.5" barrel) and carry models (4" barrel) and has various sight options available. SIG offers choice of a stainless steel finish, a Nitron dark finish, or a two-tone Nitron and stainless look.

The TAC OPS and Scorpion versions feature a Picatinny rail, night sights, and a threaded barrel to allow the user to attach a sound suppressor.
