The LTXG Grip Module uses a tungsten-infused polymer that is then molded into the part. This patent-pending process results in a grip module that has the weight of steel and the flex of polymer. We've taken this a step further and laser-stippled the grip module for a more aggressive gripping surface. Install your P320 Fire Control Unit into the LTXG, and youll have one of the flattest, softest shooting pistols on the range. Requires complete P320 Fire Control Unit and X5 or Full-size slide assembly. Compatible with magwell and weight (sold separately).
