Gun Parts(Numrich) has them. It doesn't have to be for a DS, any of the later Colts that had them will work I had a spare for a Python and put it in my Late model DS. Find a piece of plastic and cut a piece to fit and stick it in place with a spot of silicone, that will get you by, I've done it. Think I used a heavy duty weed eater cord. Look around, you will find something that will get you by.
