The Sig Sauer P320-M17 9mm X-Change Kit gives you a straightforward way to convert your existing P320 platform into a military-spec M17 configuration. This kit ships with a 4.7" slide assembly in Coyote Brown and includes both 17-round and 21-round magazines, so you get flexibility for duty, training, or sport shooting right out of the box. If you already own a P320 and want to explore the ergonomics and handling that won the U.S. Army's rigorous Modular Handgun System competition, this is the smart upgrade path.
Built around the same modular engineering that made the M17 the military's choice, the X-Change Kit maintains the P320's legendary modularity while bringing you closer to the specs of the actual service weapon. The coyote brown finish pairs durability with a professional aesthetic that works equally well at the range or in a duty holster. The kit's real value lies in its simplicity: swap components on your existing P320 firing control unit, and you've got an M17-pattern handgun configured for serious use.
One important detail: this kit is designed for 9mm, .357 SIG, or .40 S&W firing control units. If your P320 runs a .45 ACP or 10mm FCU, this kit won't work with it—compatibility matters with modular platforms, so verify your current FCU caliber before ordering.
