PS: For some reason I didn't envision the these laminate synthetic grips to be so hard/dense, but they are! the grip is in the sharp edges of the contours. They are very rigid; no deformation/spongy effect like the standard rubber grips that "stick" to your hand hold but the grip itself will move in the shear direction.
Again, totally different, but I like them both.
Not sure if this effects perceived recoil for sensitive shooters...
