There are several stock makers who provide recoil reduction systems for conventional stocks. I have two of them, a JS Air Cushion on my primary Skeet gun and a Shockmaster on my primary trap gun. Unfortunately, these are not a practical investment for your typical HD gun.Blackhawk is the only maker I'm aware of with a dedicated recoil reduction system, non-pistol grip stock.
