If it's a rubber one, just bend it out a bit. A few whacks with the palm of the hand and a few choice cuss words is all I ever needed. The one I put on my old Security Six was a nylon one. I really prefer the rubber. The wood ones are pretty, but that nylon one overlapped the grip frame and was a little sharp. First time I fired it with hot loads, it cut two slits in the palm of my hand bad enough to draw blood. I had to trim it down with a knife to match it to the grip frame. The SP101 or GP100, not having the same type grip frame, wouldn't not be a problem, but a K frame would, possibly. I had a rubber one on my SP101 I really liked and have rubber ones on my 3" Taurus 66 and 4" M10 HB now.
