The The SIG Sauer Caliber X‑Change Kit — P320 M17 (4.7″, Coyote) is a factory conversion kit that lets you transform a P320 fire‑control unit into the M17 configuration used by the U.S. military. The kit ships as a complete upper/assembly set: a coyote‑tan PVD 4.7″ M17 slide, 4.7″ barrel and recoil assembly, a coyote carry‑length grip module, and three magazines (one 17‑round and two extended 21‑rounds). The slide is optics‑ready with the SIG‑LOC MHS footprint (ROMEO‑M17 compatible) and comes with a SIGLITE front night sight and removable rear night‑sight plate for low‑light acquisition. It’s an OEM, drop‑in factory option for building an M17‑style full‑size 9mm without aftermarket gunsmithing — just pair it with a compatible P320 FCU and you’re ready.
