Rattles around - Wilson Combat Sig Sauer WCP320/365 Tungsten Grip Weights

The Grip Weights will certainly work as designed. But they rattle around in the grip. Given that the weights and the grip both come from Wilson Combat, they could have been better engineered and better manufactured to avoid this. Or they could have given you 25 cents in installation materials so you can install it without it rattling around. I found a helpful link on youtube on how to solve the problem using marine grade heat shrink tubing. Easy fix. But I expect better from Wilson Combat. In retrospect, I would not have bought the grip or the weight kit. I would have returned both but I am beyond my return period on the grip.
