I don't have a dog in this hunt (I don't sell the Peru wood grips any longer) so I'm coming from a neutral standpoint.

Just out of curiosity I bought a few of the grips linked above (on Cuda/Challenger) and they are ok, but they are not nearly as nice as the Peruvian examples. The difference is the shape is a stylized version of what pistol grip might be, but they are quite a bit different in shape as compared to originals (the Peru grips are VERY accurate to OEMs). Also, the finish is not as refined or polished as the Peru grips are, it looks like a decent sanding job with a quick spray of clear coat (you can feel and see imperfections in the clear coat).
