The Picatinny rail features a SIG SAUER® Mini Red Dot sight that works in concert with the optional front combat sight. The trigger housing is machined from an aircraft grade aluminum alloy forging with a hard-coat anodized finish designed to survive extreme conditions. The pistol comes equipped with a smooth two-stage trigger, ambidextrous safety and is designed to accept standard AR magazines.
