The SIG Sauer Caliber X‑Change Kit — P320 M17 (CALX‑M17‑CSS‑MS‑10) converts your P320 fire‑control unit into a civilian M17‑style full‑size pistol. Finished in Coyote‑tan PVD, the factory kit ships as a complete drop‑in assembly: a 4.7″ optics‑ready M17 slide, barrel and recoil assembly, a coyote carry/full‑size grip module with manual safety, and three 10‑round magazines for 10+1 capacity. The slide accepts ROMEO‑M17/MHS optics (SIG‑LOC footprint) and includes SIGLITE sighting options with a removable rear night‑sight plate — delivering military styling and modern optics capability without gunsmithing. Intended for straightforward conversion, the Cal‑X kit is ideal for owners who want an OEM M17 build in a state‑compliant mag configuration; verify FCU compatibility and local magazine limits before ordering.
