3 piece kit
Adds 1.5 ounces when installed
Drop-in compatible with all Wilson Combat WCP320 (all sizes), WCP365 (all sizes), and Sig 320 X-Compact modules

Feels great!!!

Feels more balanced now especially with a weapon light mounted on the front. The small weights went in nice and snug. I used a thin piece of self-fusing silicon tape (coax wrap tape from my ham radio kit) on the center weight to keep it from rattling.

Helps balance the small size polymer grip.

Just need silicone or shrink tubing to create a snug fit. Although, if made slightly larger in diameter, they would fit tightly on their own. I don't mind using shrink tubing to get the desired tight fit. I really like fact that they are quickly and easilly removable. In a pinch you can use hot glue glue gun to secure them at the top, if you do, just make sure you leave enough room for the FCU to seat fully. Either way, the fact that they are loose is not a problem. That being said, you probably wouldnt like the result if you don't use shrink tubing or silicone to secure them. If you dont, all 3 will rattle.

Little extra goes a long ways

Installed in my p320 W/C compact grip module and it added just a little more balance and control for shot follow up. A little tape on the larger diameter rod is all it took to make it rattle free.

Great addition to my P320 M18

These weights give balance to my pistol, so it’s not so too heavy. I used painter tape to secure them in place and it worked fine. Tip quality from WC!

Easy weight solution

Wanted a little more weight in my polymer grip module... Works great, easy to install. I used some silicon to keep it from rattling. It will also fit the Sig brand Xcarry grip module.

Works as advertised

Adding one or more of these weights shifts the balance back over the hand, which for an XL length barrel/slide is great. Also improves the balance in the standard length P365 barrel/slide. Only drawback is they are loose and therefore noisy. I might consider a thin, foam wrap, or even tape with a little above the top to remove them with.
