TXG

The term “TXG” refers to SIG SAUER’s proprietary P320 grip module design using a special material composed of tungsten-infused polymer. The advantage of the TXG design is; it not only delivers a durable grip module with the feel and flex of polymer, but the infused tungsten helps make the grip module heavier. These unique attributes offer recoil-softening properties. Most precision and competitive handgun shooters prefer a slightly heavier overall weight for their firearm to reduce recoil and “muzzle flip,” helping them mitigate recoil and execute follow-up shots more quickly. https://www.sigsauer.com/txg-grip-module.html
