SIG Sauer M18 9mm Pistol 3.9" Barrel Coyote 3x10rd Mags

The SIG Sauer M18 delivers military-proven performance in a compact striker-fired platform designed for serious applications. This coyote tan variant includes three 10-round magazines and maintains the same specifications that earned U.S. military adoption.

What Makes This Different

The M18 incorporates SIG's P320 modular fire control unit, allowing complete customization of grip modules, barrel lengths, and slide assemblies. Unlike traditional pistols with serialized frames, the FCU system enables users to transform calibers and configurations without purchasing additional firearms. The striker-fired action provides consistent trigger pull weights and eliminates external hammer snag points.

Key Features

• Modular P320 fire control unit enables complete configuration changes
• 3.9-inch carbon steel barrel with Nitron finish for corrosion resistance
• Coyote tan Cerakote slide and frame finish matches military specifications
• SIGLITE night sights with tritium inserts for low-light accuracy
• Ambidextrous slide catch and reversible magazine release
• M1913 Picatinny rail accommodates lights and laser accessories
• Three 10-round steel magazines with witness holes

Field testing demonstrates sub-4-inch groups at 25 yards with quality ammunition. The 15-pound recoil spring system manages 9mm recoil effectively while cycling reliably through temperature extremes from -40°F to 140°F. Law enforcement agencies report function rates exceeding 99.8% through 5,000-round evaluations.
