The M11-A1 pairs a compact 3.9 in slide with a durable stainless construction and Nitron finish, delivering a proven P229-pattern setup without an accessory rail. Its black hard-coat anodized aluminum-alloy frame keeps weight manageable while maintaining strength.
Controls are intuitive and left-side oriented, including the decocking lever, slide catch, and takedown levers, with a left-side push-button magazine release. The exposed spur hammer and DA/SA action are complemented by SIG's Short Reset Trigger for quick, consistent follow-up shots.
SIGLITE 3-dot tritium night sights are dovetailed front and rear, offering low-profile durability and a 5.7 in sight radius. The slide uses rear serrations only, and the squared, flat-front trigger guard with horizontal serrations contributes to a streamlined, compact profile.
This model includes a factory MIL-STD UID label on the frame (MFR 1EF82, PNO M11-A1) with a Data Matrix code. Dimensions are 7.1 in overall length, 5.4 in height, and 1.5 in width, with an approximate weight of 32 oz. Factory capacity is 15+1 in 9mm Luger.
