Thank you for all the answers and comments. I actually sold the pistol and let the new owner know that I had know idea if they were factory or not, but they were well made and felt good in the hand. The new owner really liked them.
Thanks again!
Does anyone know if these are factory S&W combat grips? Bought this 686-1 today at a local store at a really good price, just curious if these are factory made. Came with a set of Houge rubber grips also, no box or docs. Thanks in advance for any help.
