Use three or four rubber bands to hold the grip on the frame. The screw fit fine, but took a firm surface and steady hand. Note, this is a PPK/S - don't know about other frames. The rubber bands hold the grip well for installation. (Use heavy duty rubber bands, or even more light weight ones.)
Pros: Great grip, good for small delicate hands
Cons: Installation not too hard, but not easy
