Sig Sauer P320 M18 Carry 9mm 3.9" Coyote 17+1 Optics Ready 320CA-9-M18-MS-1M

Sig Sauer P320 M18 Carry

The Sig Sauer P320 M18 Carry is a striker-fired 9mm pistol that brings military-grade accuracy, reliability, and durability to a civilian version. It features a 3.9-inch barrel and a capacity of 17+1 rounds. This used example comes in the original box with one 17-round magazine.

The coyote-tan PVD coated stainless steel slide includes black controls, SIGLITE front night sights, and a removable night sight rear plate. An ambidextrous manual safety and optics-ready design compatible with the SIG Romeo1PRO and Deltapoint PRO provide enhanced versatility. The carry length coyote grip module and polymer frame support a comfortable hold at an overall length of 7.2 inches, width of 1.6 inches, height of 5.5 inches, and weight of 28.1 ounces with magazine.

This model suits concealed carry and personal defense with its short tactile reset and state-compliant features. The night sights aid low-light acquisition, and the modular platform allows customization. With the included magazine, cable lock, owner's manual, and original box, it offers a complete package for shooters seeking proven military-inspired performance.
