Didn't want to sidetrack BOM's thread ( awesome job again on the wave mod!). Here's the comparison between the factory plastic grip's and the G10 WilkinsGrip's. Thickness is about the same, but do to the G10 being flat and not rounded it seem's to ride much flatter in the pocket.
L-R, Trainer with Wilkins, Factory, Ritter with Wilkins. All full size.
