SIG GRIP MOD P320X5 9MM GRY W/ GW

Description

The Sig Sauer P320 X-Series TXG Grip Module is built for competitive shooters and serious range work who want to reduce muzzle movement without adding a separate weight kit or reworking their existing P320 setup. It accepts a standard P320 fire control unit and is designed to pair with an X5 or full-size slide assembly, so it slots into an existing P320 build rather than requiring a ground-up configuration.

The defining feature here is the material: tungsten-infused polymer. Tungsten is significantly denser than steel, so even a modest infusion into the polymer matrix raises the grip module’s mass well beyond what standard polymer achieves. That extra mass sits in the grip rather than the slide, which shifts the gun’s balance point lower and rearward. In practice, that placement dampens felt recoil impulse and reduces muzzle rise between shots — both of which matter when split times count or when you are running a long training session. The polymer matrix retains some give, which means the grip does not transmit the sharp edge of recoil the way an all-metal frame would.

The module ships in Medium Grey and includes a pre-installed magwell, so it is ready to run without sourcing additional components. At 16.6 oz the grip module alone carries real heft, and that weight does the mechanical work of settling the gun without requiring any technique adjustment from the shooter. This is a straightforward upgrade for anyone already running a P320 who wants a softer, flatter shooting platform.
