I received my Delrin grips for my CS9 that BIG DOG made.
He is a first class guy all around. He offered to stay on the phone while I installed the Delrins and offered to make it right if I didn't like them for any reason. Top notch in my book.
They are a good fit and everyone I showed the CS9 to with the Delrins has commented how the Delrins feel so much better and "smaller in the hand" or "not as bulky" than the stock rubber grips.
Photos to follow.
