Have one on my 870 and I can attest to it's capability in reducing felt recoil. Mind you, it's still on a shotgun in the end so the recoil still exists; however, it does take a noticeable amount of the edge off. The only issues I have had are that it makes it a little more difficult to fully disassemble my 870, as a small portion of the pistol grip actually holds the back of the trigger assembly in place; and, I had a slight issue with sight picture through my ghost ring sights, rectified by the addition of a higher check rest available from blackhawk for the stock. All together I was pleased with it's addition on my pump gun.
