The P226 Combat with threaded barrel is designed to meet, and exceed, rigorous military standards. The P226 Combat performs like no other .9mm available. Each pistol features the military's Flat Dark Earth finish on its alloy frame and SIG's Nitron over a stainless slide. Internal parts and controls are phosphated for extreme corrosion resistance and reduced friction while the threaded barrel is hard chromed and finished in Nitron which easily passes the military's accuracy requirements even after 20,000 rounds. The P226 Combat also passes the military's 240-hour salt spray corrosion test. Outfitted with a true M1913 Picatinny rail, vertical front strap serrations and SIGLITE night sights.
