I found an original set of MOP grips for my Pocket Positive. They didn't come with the grip screw. They fit fine, but the screw that was used with my original gutta percha grips is too large in diameter, and 2 mm too long to use with the pearl grips. Obviously the threads are not correct on the gutta percha screw as well. Any ideas where I might find a correct screw? I seem to remember that there was someone on Ebay that would make screws for Colt handguns, but I don't see him having anything listed at this time. I'll post on the wanted to buy forum, but any other suggestions are appreciated.
