The TXG grip module is one of the more interesting things SIG has done with the P320's modularity. It's molded from a tungsten-infused polymer that is dramatically heavier than a standard frame — the added mass sits low in the hand, right where it does the most good, so the pistol tracks flatter and returns to target faster without changing anything about the slide or the fire control unit.

This is the Carry size in large grip, finished in gray, compatible with 9mm, .40 S&W, and .357 SIG P320 fire control units. For competition shooters and anyone who prioritizes shootability over carry weight, swapping to a TXG is one of the cheapest meaningful upgrades available for the platform.
