A full line of 1911-styled pistols is produced by SIG Sauer in Newington, New Hampshire, in the United States. The first versions were fairly similar to the Colt M1911 Pistol, which was created by John M. Browning and remained the standard sidearm in the US for around 70 years before being substituted by the Beretta M9. The SIG-Sauer 1911 is a line of 1911-inspired handguns made by the American firm SIG Sauer Inc. It was originally known as the GSR (Granite Series Revolution). The distinctive slide profile of SIG-Sauer 1911 handguns serves as its primary distinguishing feature. The iconic 1911 was redesigned with contemporary enhancements and SIG dependability while maintaining its renowned accuracy and ergonomics. The most renowned handgun in history has been updated by SIG with enhancements to satisfy the needs of modern shooters. SIG SAUER 1911s are made to last as long as Browning's original design because of their all-metal frames, tough design, and protective coatings.
