The SIG M18 Commemorative delivers a faithful P320 as the Army and Marine Corps pistols.

SIG Sauer’s going back to the well, and we couldn’t be more happy about it. The SIG M18 Commemorative will bring to market 5,000 units of the P320-based pistol adopted by the U.S. Army and U.S. Marine Corps. The limited-edition release features the same components, coatings and markings as the Army and Marine pistols.

“The M18-Commemorative is an exciting release for the commercial market, and much like the M17-Commemorative will be coveted by members of the military, veterans, collectors, and firearm enthusiasts alike,” said Tom Taylor, Chief Marketing Officer and Executive Vice President, Commercial Sales. “Only 5,000 of the M18-Commemorative pistols are being manufactured, and include all the required modular handgun system markings including the U.S. Army’s unique identifier (UID) and SIG SAUER Cage Code, making the M18-Commemorative identical to the pistol currently in service with the U.S. military.”

In 2018, SIG brought out a similar variant with the M17 Commemorative. Now shooters can get the more concealable variant, complete with some impressive bonuses. The pistol comes with a certificate of authenticity and challenge coin. Each features serial numbers matching the pistol, which run M18-0001 through M18-5000.

The M18 Commemorative striker-fired pistol chambers 9mm. It features a coyote carry-length grip module and PVD-coated stainless steel slide. The slide comes with the same optic cut specified by the MHS contract. It includes the original coyote-tan colored controls, ambi safety and SIGLITE sights. The pistol ships with two 21-round magazines and one 17-rounder. Better still, it ships in the same cardboard packaging as delivered to the U.S. Army. For even more info, please visit
