About SIG Sauer
SIG Sauer, Inc. is the American branch of a firearms line that goes back to the Swiss Industrial Company (SIG), founded in 1853. The U.S. company started in January 1985 as SIGARMS in Tysons, Virginia, to import the P220 and P230 pistols. It moved to Herndon, Virginia in 1987, when the P225, P226 and P228 arrived, and then to Exeter, New Hampshire in 1990, where it began making guns in the United States. In October 2000 the U.S. operations were sold to L&O Holding, which still owns them. In 2007 the company took the name SIG Sauer, Inc.
SIG is now one of the most important gun makers for American shooters and agencies. Its P226 and P229 became police and military standards. In January 2017 the U.S. Army picked the P320 for its Modular Handgun System, adopted as the M17 and M18. In April 2022 the Army chose SIG’s M7 rifle and M250 automatic rifle for the Next Generation Squad Weapon program. Beyond firearms, the company now makes suppressors, optics and ammunition, and it runs the SIG Sauer Academy and a SIG Experience Center in Epping, New Hampshire.
