Detailed Description


Adding some weight to your WCP320 polymer grip module can enhance your recoil control and improve the balance and handling of your handgun.

These solid tungsten slide-in weights are non-magnetic, corrosion resistant and have a drop-in fit to your Wilson Combat WCP320 grip module or factory SIG SAUER X-Compact grips.

  • Three solid tungsten rod weights for WCP320 module that total 42g/1.5 ounces
  •  Drop-in fit compatible with Wilson Combat WCP320 or SIG SAUER 320 X-Compact grip module


NOTEBecause these weights are a drop-in fit, apply a dab of heavy grease to prevent any potential rattle with some frames. For a more permanent installation, silicone caulk adhesive is a great choice.

Great addition to a great grip module
These weights took about 30 seconds to install. Pressed into place firmly they fit snuggly and do not rattle. I did not use any adhesive. With the Wilson grip module and tungsten weights the P320 now feels much more substantial and has better balance in the hand. A joy to shoot!
Great but needs adhesive
these work great and fit but will flop around if not secured by a glue or silicon. I used silicone caulk to seal these weights in place
Awesome upgrade
These add just enough weight to the grip module! My XCompact feels much better in hand and has less perceived recoil after installing these. The kit does NOT come with silicone but it is advertised as not coming with it. It's available everywhere, and I actually had some laying around. The installation was a breeze. Be sure to have Silicone, cotton swabs, rags or towels, and a punch ready. Those things make for a quick and proper install.
Almost perfect
Very satisfied overall, good feel in the hand, but like others I would be happy to pay an extra couple of $$ and not have to make an extra journey for silicone to finish the job.
Good, but not perfect
Yes they add weight, which gives the gun better balance. All three rods are way shorter than they need to be, missing the opportunity to add yet a few more grams of weight. The smaller two slots in the WC Grip Module are tapered, so the two smaller rods can be pushed in so that they are secure, the larger rod however is so loose that it literally flops around in the middle slot. I don’t know how using grease would prevent this? I used hot glue and then forced the rod all the way to the bottom which worked.
Additional supplies needed
Weight kit does Not come with the silicone needed to complete the installation.
Tungsten Grip Weight Kit w/SIG P320 X-Compact Grip Module
I installed the Tungsten Grip Weight Kit in my SIG P320 X-Compact grip module and the three rods fit perfectly and went in without any issues. I put a small amount of silicone on each rod prior to insertion to make sure they will not come out or rattle in the future. The extra weight in the grip module makes a difference when I have the 3.9" barrel and slide from my X-Carry installed on the P320 X-Compact grip module and now that configuration makes for a very balanced EDC pistol setup. Even with the standard 3.6" barrel and slide on my P320 X-Compact grip module, the extra 1.5 oz. provided by the Tungsten Grip Weight Kit seems to make a positive difference in the way the pistol feels in my hand. Nice job as usual, Wilson Combat!
