It is wonderful that we have a wide variety of choice of grips. I enjoy seeing the different designs and materials.
Also, folks have an opportunity to personalize their firearm with their choice of grips.
As I said before, I like Pachmayr grips on my M1911's for shooting. It is more function over form for me. M1911's with rubber grips just do not move in my hand under recoil which I like.
But for folks that like grips of other materials, that is great. I wish I could have fancy looking grips and shoot them well.
