I received my rubber Grip glove for my S&W Sigma 40VE yesterday. While trying to put it on my firearm, it split right at the top which deemed it unuseable. I was not pulling on the grip with a tremendous amount of force. My impression is it is cheaply made or has some dry-rot issue. I would have lubed it to make it easier to get on but that would have definitely cause some slippage issues when firing. It will be interesting as to what customer services informs me to do.
