The Sig Sauer P320-M18 9mm Carry Coyote Caliber X-Change Kit lets you transform your manual-safety P320 into the civilian M18 configuration trusted by the U.S. armed forces. This kit pairs a coyote-tan PVD coated stainless steel 3.9 inch slide with matching carry-length grip module, delivering the same accuracy, reliability, and durability as the duty pistol while remaining optic ready with the SIG-LOC MHS footprint for the ROMEO-M17 red dot (optic not included).

Designed for shooters who want a proven carry setup, this kit includes a 3.9 inch barrel, recoil spring assembly, and three 10-round magazines for compliant capacity in restricted jurisdictions. SIGLITE night sights with a removable rear night sight plate provide confident low-light aiming, while the integrated M1913 accessory rail supports lights or lasers for range use, training, or everyday carry. Backed by Sig Sauer’s reputation for thoughtful engineering and consistent performance, the P320-M18 Caliber X-Change Kit offers a refined path to a modern, modular carry pistol.
