The Marine Corps recently chose the M18 as its official sidearm. Meanwhile, all branches of the U.S. Military have issued the full-size M17 following the MHS contract award.

“Since the official selection of the M17 and M18 by the U.S. Army for the Modular Handgun System (MHS), we’ve seen significant civilian interest to own both variants of the handguns,” said Tom Taylor, Chief Marketing Officer, Executive Vice President, Commercial Sales. “The P320-based M17 and M18 are among the most tested handguns in history and the pair has been proven to be unmatched in both accuracy and reliability. We are very proud that with the P320-M18, civilians can now own the same innovation and versatility that has made either the M17 and M18 the handgun of choice for all branches of the U.S. Military.”

The P320-M18, a 9mm striker-fired pistol, comes with an exclusive “M18-XXXXXX” serial number. It includes one 17-round magazine and two 21-round magazines. The pistol features a SIGLITE front night sight and a removable night sight rear plate, as specified by the MHS contract. Additionally, the slide comes optics-ready. With the rear sight assembly removed, the SIG Sauer Electro-Optics ROMEO1Pro Optic mounts directly to the slide.

The pistol comes configured nearly identically to the U.S. Military’s models. It features black controls and a carry-length coyote-tan grip module. The slide comes coyote PVD finished, with an ambidextrous manual safety. The P320-M18 is also available in a state-compliant version and is currently listed on the Massachusetts handgun roster.
