This Sig Sauer P320 Carry Small Grip Module is a genuine factory replacement part finished in a durable coyote tan polymer. It is designed to house P320 or P250 Fire Control Units in 9mm, .40 S & W, or .357 SIG that do not require a manual safety cutout. The "Small" circumference offers a slimmer profile for better control and an easier reach to the trigger, while the "Carry" length provides a full-size grip for increased magazine capacity. This assembly is intended for use with 3.9-inch compact or carry-length slides and includes a pre-installed, reversible magazine catch for immediate use.
