reducing recoil.

[Chevyman_2000]

Well as the title says I'm looking to reduce the recoil in my Mossberg 500 bantam. I have a bad back (busted 7 vertebra 3 years ago) and the less recoil the better for myself, insurance and lawyers! i already have a shooters shirt but it's a pain with my vest. I am used to shooting a SBEII 26" gun with 3.5" hevi and the 20 is less but I want it better Whats my best options?

20 ga. Semi auto. Knoxx recoil reducing stock. You may want to try 2 3/4 in. shells also. I shoot a Benelli Nova 20 due to one too many retina tears.I dont really notice too much recoil and I shoot 3 in Nitro 7s with the factory stock.
