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.

Carry Size Grip: Weight WITHOUT the Tungsten Weight Kit is 94 grams
Carry Size Grip: Weight WITH the Tungsten Weight Kit is 138 grams
Weight increase: 47%

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).
