A product of the Swiss-German partnership of Sig Sauer, the P226 was an evolution of one of the most accurate and well-made handguns ever made, the Sig P210. The P210’s design was updated for the U.S. Army handgun competitions of the 1980s. While it failed to win the Army contract, it did become the handgun of U.S. Navy SEAL commandos.
The P226 had also made earlier inroads into the U.S. military service. Navy SEALs, wary of the Beretta M9 after a handful of incidents involving cracked slides and injuries, adopted the P226 as the Mark 25. The Pentagon was slower to adopt Glock handguns, but the Austrian handguns eventually found their way into the 75th Ranger Regiment and Delta Force.
