The Hideout Grips took quite a bit of alteration for my J Frame. A Comp 1 still binds on the grip, however an HKS works fine after alteration. No issues with the K Frame Hideout Grip. The J frame came as their smooth grip. The K Frame was their textured grip, which means it appears to have been sandblasted or beadblasted for a slight texture. I stippled both grips, which at least for me works very well.
