The grips on this "J" frame, are; ALTAMONT, Combat grips. Although they are very nice looking, they are not made so that Safariland speed loaders can be used. They do not have sufficient relief to except speed loaders. So much for "Combat" grips. I tried to get some input from the company to fix my grips, but was blown off. I thought I would use a dremmel to sand the wood, to increase relief on the cylinder side, but I don't know how to finish the wood after I have sanded. Any suggestions?
