Holster Wear on Grips?

[mm]

We all know about the effect holsters have on the bluing. But what, if any holster wear, can occur on wood and bakelite grips? In other words, could one expect that a gun that was used very little, with an excellent bore, little-if-any wear on its moving parts, but shows only 85% bluing from holster wear could have excellent wood or bakelite grips? Or would the grips also be effected by constant contact with the leather holster? mm
