Description
The Sig Sauer P320 M18 is the commercial variant of the U.S. military’s officially adopted sidearm for the Marine Corps, bringing battle-proven performance to civilian shooters. Chambered in 9mm, the M18 features a 3.9" barrel, coyote-tan finish, and a modular grip frame system with ambidextrous controls.
This pistol comes optics-ready with a factory slide cut for direct-mounting red dots like the Sig ROMEO1 PRO or Leupold DeltaPoint Pro. The P320 M18 includes SigLite front night sights and a rear sight plate that allows co-witnessing when an optic is mounted. With a flat-face trigger and integrated manual safety, it combines modern modularity with classic control preferences.
Includes one 17-round and two 21-round magazines, making it range- and duty-ready out of the box.
