Armory Craft recognizes the loss of polymer firearms compared to the all-metal ancestors is the stabilizing effect of mass. One of the heaviest metals available without a nuclear materials license is tungsten. By installing tungsten carbide weight rods in the pre-existing openings within the Wilson Combat grip module for the P320, total mass is increased by a whopping 47% and the results are an obvious improvement in grip stability in the hand, less jitter and shake that affects accuracy, and a reduction in recoil movement for a faster return to target. Precision-cut tungsten carbide rods install easily by dropping into pre-existing slots in the Wilson Combat grip module, and a dab of the silicone glue (included with the kit) keeps them solidly in place (silicone glue is easily removed if you desire to take the rods out in the future).

Carry Size Grip: Weight WITHOUT the Tungsten Weight Kit is 94 grams
