I saw this last evening in my LGS and thought it was interesting. I'm not a Sig fan and I certainly wouldn't buy a Sig 1911-like item. The grips on this are steel, I think, and the stars are raised. Seems like this might become an issue if you were shooting several mags in a row. I did like the distressed look and the star pattern.
