Description
The Sig Sauer TXG X-Series grip module is a small-profile replacement module for the P320 platform that uses a tungsten-infused heavy polymer for added mass and polymer flexibility. The patent-pending manufacturing process embeds tungsten in the polymer to increase the modules weight while retaining polymer characteristics. This grip module requires a complete P320 Fire Control Unit and an X5 or full-size slide assembly for a complete pistol build; the magwell and internal weight are not included.
