I just ordered a set of these for my 317, and can't wait to slap them on. I have a set of VZs on my 1911, and they're the cat's pajamas. The 1911 grips feel lighter than the stock rubber ones, I imagine the J frame grips should be lighter than the stock rubber too. If the G10 J-frame grips catch on, they'll probably start to offer them in micarta too, which will be lighter than G10 if that's an issue for some folks.
First post, long time lurker. Howdy folks!
