wood grips on sheridans are quite tough... because of only having one screw, the grips either have to connect, parts have to sink in, or they have to drill the bit from the trigger rod which even still i dont like on my plastic ones, the rod can move.. its not nearly as effective as two screws, you have to wonder what they were thinking...
looks like this guy knows how to make a nice set of gripsI might make a set, really want a pre made set tho. to make a set will take a lot of hours!
