The TXG grip module brings added mass close to the shooter’s hand to promote reduced muzzle rise and a more controlled follow-up feel during ranged practice and competitive shooting. Its tungsten-infused polymer construction provides substantial weight without sacrificing the ergonomic benefits of a polymer module, and the extended beavertail improves hand placement for better recoil management. For shooters upgrading a P320 platform, the TXG offers a pragmatic way to change the handling characteristics without altering the Fire Control Unit.
