  1. Very good product
    After watching the video, I went at the switch over.

    Took me about an hour, as I had to secure the larger weight (I bought the weight set), and I also had to assemble the mag release button.

    Overall greatly improved fit over the Sig frame, slimmer, and a bit of a magwell too.

    I'm glad I made this change over to the Wilson Grip Module.

  2. Hand down best grip for the money
    I bought my grip module for a custom p320 build and could not be happier, the stippling is great and everything dropped right in, recently I added the grip weights to it and so far I love having the extra weight. I would like to see a plug of some sort to stop th rattle of the weights but that's minor. The thumb groove makes it super easy to get to the mag release and the flared magwell makes for some amazing reloads.
