Manufacture SIG Sauer firearms are manufactured in Eckernförde, Germany by Sig Sauer, GmbH and in Newington, New Hampshire, United States by SIG Sauer Inc., (formerly SIGARMS Inc.).

Sauer & Sohn, John Rigby & Company, German Sport Guns GmbH and Blaser Jagdwaffen Gmbh are subsidiaries of Luke and Ortmeier Gruppe of Emsdetten, Germany. Copies of the P226 are produced in China by Norinco, under the name of NP22. These were subcontracted to the Zhejiang Xinhua Machinery Manufacturing Co., Ltd. (浙江省机电集团), known as State Factory 972 or known as the Xinhua Factory and Zhejiang Factory. The variants consist of the NP22, NP22A, NP34, NP56 and the NP58. The SDM XM9 is a variant of the NP22 chambered in 9x21mm for countries that don't allow any pistol calibers that are only for the military and police. The LP3 and LP4 are versions of the NP22 and NP34 with manual safeties on the slide. The NP762 is chambered to fire 7.62x25mm bullets, which were exported in 2019. They were first made by Xinhua in 1999 and were known then as the NP2000 for potential contracts in China for the PLA and various law enforcement agencies.
