Seeing how a Benelli M1 Super 90 is recoil operated, will the installation of a mercury recoil reducer in the butt stock cause problems with the reliability of this gun?
HW, recoil reducers only add weight to the stock thus reducing felt recoil. They don't reduce the actual working recoil of the gun. I've installed them in Brownings with no problem so I wouldn't expect any from the Benelli. George
C, I didn't install them in my guns they were in customer guns. I haven't heard any complaints and they test fired fine. As to them being worth it, that's an individual thing. I don't use them in my own shotguns but I just never felt the need. George
