Sig Sauer P320/M18 Coyote Tan Polymer Grip Module, Medium

The Sig Sauer P320/M18 Coyote Tan Polymer Grip Module (Sig Sauer part no. 8901484) is a Medium-size, X-Carry/M18-pattern grip frame built for Sig’s modular P320 and M18 pistol platform. Sig Sauer engineers the P320 and M18 around a removable Fire Control Unit, which means the polymer grip module itself is a non-serialized accessory you can swap without any gunsmithing. This Coyote Tan module lets you change the size, color, or feel of your grip in minutes, whether you’re matching a duty or field build or just want a fresh look, and it’s cut to accept a manual-safety-equipped Fire Control Unit in 9mm, .357 SIG, or .40 S&W. It drops straight onto your existing Fire Control Unit with no fitting required.
