The SIG Sauer P226 is perhaps SIG’s most famous handgun. This pistol was introduced in the 1980s to compete for the United States army contract as the new service handgun to replace the Colt M1911A1. For context, the P226 is essentially a double stacked P220 rechambered for 9mm. The P226 and Beretta M9 became the final competitors out of an initially much larger field, with Beretta emerging as the victor. However, the P226R was still adopted as the main handgun of the United States Navy SEALs, but it was later replaced by the Glock 19.
Standard capacity of the P226 is 15 rounds, but longer 18 round magazines are being made by Mec Gar. P226 pistols today are still in service with many law enforcement and military units all around the world.
