Sig Sauer P320 M18 – Compact Military Precision for Everyday Carry
The Sig Sauer P320 M18 brings the exact performance, reliability, and modularity of the U.S. Military’s M18 service pistol to civilian hands. As the compact version of the M17, the M18 is designed for those who need duty-grade performance in a more carry-friendly package—ideal for home defense, concealed carry, or range use.
Featuring a coyote-tan PVD-coated slide, optic-ready design, and SigLite night sights, the P320 M18 combines the versatility of the P320 platform with the battle-proven features trusted by America’s Armed Forces.
Key Features:

Military-Proven Design
The P320 M18 is the civilian version of the U.S. military’s M18 sidearm, currently in use by all branches of the U.S. Armed Forces. -
Compact & Carry-Friendly

Factory-milled to accept red dot optics with a removable rear sight plate (compatible with SIG ROMEO-M17 and similar optics). -

Tritium 3-dot night sights provide fast target acquisition in low-light conditions. -
