I was looking for a rubber grip to fit a Ruger Service Six. I found several that did fit a Security Six but the pins in the pistol handle did not line up with the grip holes. Numrich had Mustang Rangefield Grips without the screw. A search of the net found several people asking the question if anybody knew the screw size. No reply.


After cleaning out the rubber from the screw hole I went to Lowe's and found Black Screw packet of 4 (H#885533 for $1.17) - size 6-32 x 1 inch that works.

I hope this helps others in the same situation.
