Contact tarawa from this forum, he can make you a milled, slide in spacer out of black delrin. You have to measure the distance between the barrels at the front and back for him and he will make it to fit your gun. You then have to remove the front sight bracket by driving out the holding pin. The spacer will then slide in from the front and you then replace the sight bracket and pin. Very slick and neat, and it matches the barrels well. Tell George I sent you to him! Bob H.
