This is superb info. The M1's in particular respond very well to even just a little love, but I can attest-- we Benelli M1 owners have got to access that recoil tube and spring and do as the Man remarkable says; it'll help keep your gun working hard for thousands of rounds-- which mine has experienced-- I have had tremendous luck with my M1 Super 90 after working it hard for 12 seasons, letting it get beat up in duck boats, muddy fields, ice, you name it. Thanks again, remarkable! Bill
