Designed to meet, and exceed, rigorous military standards, the M11-A1 Compact performs like no other 9mm available. This pistol features the black hard-coat finish on its alloy frame and SIG's Nitron finish over a stainless slide. Internal parts and controls are phosphated for extreme corrosion resistance and reduced friction while the barrel is finished in Nitron which easily passes the military's accuracy requirements, even after 20,000 rounds. This pistol also passes the military's 240-hour salt spray corrosion test. Additional features include vertical front strap serrations and SIGLITE night sights.
