I had a hunter come to Iowa this past week, he shoots sporting clays comptitively. he had a Beretta auto loader that had a C&H mercury recoil compensator in the stock and a Hi Viz butt pad and Comp N Choke ported choke tubes and I have to tell you I have never shot an easier kicking gun. It was such a light recoil that I hit every clay target thown for me. I almost made him leave the gun in Iowa before he went home. I was so impressed with the result that I have ordered the same choke tubes, mercury compensator and butt pad for my over under. Can't wait to try them out. I am as skeptical as anyone about this kind of stuff, but I am now a believer. I do not imagine I will get the same exact result from an over under as he did with his automatic, an automatic kicks less just by it's very nature, but I am now convinced that even a little recoil reduction will make me a better shooter. The brands above are not the only ones available, but these are the ones I have now ordered for my gun except I think I will get the Limb saver butt pad. You can find all of these cos. on the internet.
