The SIG SAUER P229 M11-A1 NS is a compact 9mm DA/SA (double-action/single-action) hammer-fired semi-automatic pistol inspired by SIG Sauer’s military M11 service pistol heritage. Combining the proven P229 platform with M11-style features, this model offers a rugged alloy-frame design, corrosion-resistant finish, and traditional SIG Sauer controls in a compact configuration.

The M11-A1 features a Nitron-coated stainless steel slide, lightweight alloy frame, SIGLITE night sights, and a 3.9-inch barrel. Its traditional DA/SA trigger system includes a decocking lever, while the compact double-stack frame provides a 15-round 9mm magazine capacity.
