Sig Sauer P320 M18 9mm 3.9 Inch Coyote Handgun

Description

The P320 M18 is the commercial release of the pistol adopted across all branches of the U.S. Military, and it suits shooters who want a carry-length platform built around the same specifications that had to survive military evaluation. The grip module and slide wear Coyote PVD finish — the same color scheme as the issued weapon — rather than a standard blued or black configuration, which matters if visual consistency with other gear is a priority.

The striker-fired action keeps the trigger pull consistent from first round to last, which is a meaningful advantage over traditional double-action/single-action designs where the pull weight changes after the first shot. The manual safety is ambidextrous, so it functions without adjustment for either hand. The slide is optic-ready and ships with a removable rear sight plate: the night sight rear can come off to mount a compatible red dot directly, and the SIGLITE front sight remains in place, giving you a co-witness reference without an adapter. That setup lets you run irons by default and add an optic when you’re ready without additional machining.

The FCU on this variant incorporates a magazine disconnect — a mechanical change made for the California market that prevents the pistol from firing when the magazine is removed. This is a functional difference from the standard commercial M18 and is worth understanding before you handle the trigger in a dry-fire context. Three 10-round magazines are included in the box, so you have spares without an additional purchase at the outset.
