I picked these up for my girlfriend's P938. The cross cut pattern, (double diamond is what the seller lists them as), makes for a really nice textured grip. Needless to say, she loves them.
"Spresser Knife Works"
Check the man out sometime. He was a pleasure to do business with, quick shipping, large variety of grips made from a range of materials for several different guns, and I feel all of his products are reasonably priced.
I noticed this pattern on a set of grips for a different pistol; When I told him how I liked the design but I'd like to buy a set that are pink; he asked what pistol I would be putting them on, and then made me the set that very same day.
A couple links for his products.
