There are these.....

Kick-eze recoil pads, lengthening the forcing cones, but getting it to fit you is the only real way to help in reducing recoil...
I have a K-80 and a KX-5 for shooting trap, my field guns are Browning 525 O/U shotguns with the stocks hot oil bent to fit me with the Kick-eze pads on them.
I have a 870 12ga., which is the first gun I ever bought, and it`s never going anywhere.
Then I bought a 525 in 20 ga. really great gun, then came the 28 ga. 525, had I bought the 28 ga. first I probably would have never bought the 20 ga. what a sweet thing that 28 ga. is....
I didn`t believe the 28 ga. guy`s, what a fool I was, that thing is sooo light and recoils like a cap gun...Hell, a whole box of shells fits in your vest pocket....try that with a 12 ga.....
I have ran the handicap 27 yds. clean so many times with that 28 ga. it isn't even funny, others don`t think so highly of getting beat by a field gun, but a full choke and 3/4 oz. of shot will get you there....
I`ve owned 4 Benelli`s, good guns but not for me, the people who bought them are happy with them and that`s all that matters.
Good luck, I hope you get it where it needs to be.
Phil.
P.S...Lots of dove, quail and pheasant have folded to that pair of 525`s, I don`t hesitate to grab either of them....
