The SIG Sauer P229 is a full-sized service pistol made by SIG Sauer.

Schweizerische Industrie Gesellschaft (SIG) is a Swiss company, now known as Sig Sauer AG. In 1975, SIG entered into an agreement with German gun manufacturer J.P. Sauer & Sohn to develop and market a new handgun the P220 which became the P229. 

Introduced in 1992, the P229 is an upgrade to the P228 being an identical compact firearm often used for duty or concealed carry purposes. Developed specifically for the US market and assembled with both German and US-made parts, the P229 features a heavier slide to tolerate more powerful rounds than the P228 is incapable of. The standard version features a DA/SA trigger.
