Sig Sauer
The Sig Sauer P320-M18 Carry is a purpose-built 9mm pistol engineered for shooters who demand a reliable, compact sidearm that doesn't compromise on capability. Built on Sig's modular P320 platform, the M18 bridges the gap between concealed carry and duty performance—offering the same proven action trusted by military and law enforcement, packaged in a carry-friendly footprint. With a 3.9-inch barrel, 7.2-inch overall length, and stainless steel construction finished in Coyote PVD, this is a gun that handles equally well in a holster or on the nightstand.
What sets the M18 apart is its versatility. The optic-ready slide accepts both Romeo1PRO and Deltapoint PRO reflex sights for those who run a mounted optic, while the removable night sight plate lets you choose your setup. The coyote grip module is sized for the carry profile, and the ambidextrous manual safety means left and right-handers operate it the same way. The striker-fired trigger delivers a short, tactile reset—familiar to anyone who's shot a modern polymer pistol, quick to reset for follow-up shots.
This particular M18 comes configured for states with magazine capacity restrictions, shipping with three 10-round steel magazines. That 10-round limit keeps it compliant in places like Massachusetts while maintaining the same ergonomics and point-of-aim as the full-capacity variants. It's a legitimate solution for carry in restrictive jurisdictions—not a compromise gun, just a P320 M18 that obeys local law. The gun weighs 28.1 ounces loaded, sits 5.5 inches tall, and presents a clean 5.8-inch sight radius for accurate shooting from the draw.
Sig's reputation for durability is built into every P320. This stainless steel slide and frame combination resists corrosion in field conditions, and the proven P320 action has logged countless rounds downrange. Whether your carry mission is daily concealment, truck gun, or primary backup, the M18 gives you a serious 9mm in a package that works.

Yes. The slide is optic-ready and compatible with Romeo1PRO and Deltapoint PRO reflex sights. The removable night sight rear plate allows you to set up the gun the way you want it.
The ambidextrous manual safety operates fully from either side—no compromises. Left-handers get the same positive engagement and ease of manipulation as right-handers, making the M18 equally practical for both.
The M18 ships with three 10-round steel magazines and the pistol itself. It does not include higher-capacity magazines; any additional magazines would need to be purchased separately and must comply with your local laws.
