Description

The commercialized version of the U.S. Military's newest service pistol, the P320 M18 is a polymer striker-fired semi-automatic pistol chambered in 9mm Luger (9mm Parabellum/9x19mm). With a 3.6" barrel and shortened overall slide length compared to the M17 models, the M18 replicates the military's compact M18 officer model. Though the overall length is shorter for faster draws from holster, more comfort when carried inside-the-waistband, and a faster cyclic rate, the grip of the pistol is still a full-size length and carries 17 rounds of 9mm in a flush magazineupped to 21 with the included extended magazines. The pistol is finished in a coyote PVD finish with tan grip module to visually differentiate it from many other commercial P320 pistols. A pioneer in the firearms industry, the P320 was derived from Sig's P250 hammer-fired pistol and adapted to meet the requirements of the U.S. Army's M17 combat handgun trials. One feature which aided in the P320's success was its simple and toolless takedown procedure and ability to change frames, slides, and barrels in only a few short steps, making it possible to change the P320 from a carry-size subcompact all the way up to an oversized competition full-size pistol with the twist and removal of the takedown lever. The platform of a removable Firing Control Unit (FCU) with modular grips and parts was paralleled in the market-leading Sig Sauer P365 concealed carry optimized pistol series and led other companies to follow suit with models such as the Ruger RXM, IWI Masada, Taurus GX4, and Springfield Echelon. The P320 M18 has a coyote tan medium grip size module with an ambidextrous manual thumb safety as well as a loaded chamber indicator on the top of the barrel hood. The pistol sights are Sig Sauer's Siglite 3-dot green tritium night sights with white outlines for quick target acquisition in the daylight and fast location of the gun in darkness. The rear sight also doubles as an optics cover plate over the top of the P320 M17/M18 optic cut. This optic cut pattern is compatible with slide-mounted optics utilizing the Leupold DeltaPoint Pro, Eotech EFLX, and Sig Sauer Romeo1 Pro footprints. This pistol is in like-new condition with some of the factory grease even still present on the internals. The handgun includes the original factory hard case, one OEM 17-round magazine, two OEM 21-round magazines, chamber flag, sticker, and user manual.
