Alas, no wood for me...
I can't keep wood grips looking nice for the same reason I have to carry stainless or polymer guns: corrosive sweat. I had some nice Cocobolo grips on my last SA 1911, but after three months of frequent handling, they may as well have been made of old pine roofing shingles. Same with revolver grips.
+1 for the Ergo Grips. Very positive gripping surface (like skateboard tape molded into hard plastic) and impervious to harm...
