Back when the government was giving away free money I bought these 2 sets of grips from Sack Peterson. I told him I'd be glad to wait however long to ensure a good match on color and bark. Just over three months later he sent my grips. Well the fitting sucked. Not just a bit proud on the edges but sloppily fit on the frame, for the blackhawk grips. I was able to clean it up and had just enough to get it fit on the edges of the grip frame. I shaped them some and repolished them. Good thing I'm a craftsman, a normal not handy person wouldn't have been able to. The color is matched well and there is no bark on the left side, with only a trace on the right. Overall I'm happy with the color and bark.
The GP 100 panels are excellent in match. But they sucked in fit. The left side would fit but wasn't shaped just right in my rubber body, but the right side would not fit at all. It was 1/8" long and the shape was a bit off. I was able to fit them with relative ease.
Since I was able to put two hours in, and successfully fixed these grips I'm moderately happy. Not sure if I love them or not until I shoot the guns a while with them.
