My 835 came factory ported. It helps with muzzle rise on 3 1/2"mag loads with 1 1/4 oz loads of steel shot or 1 3/8 oz lead turkey loads. It does not seem very effective on 2 3/4" shells. At least I don't notice any difference with other shotguns. If your not hunting turkey it probably wont change much. The best recoil reducer I have found is a flex tech stock. Beneli and Thompson Center have them as an option from the factory. Cuts recoil 40% according to the adds. I will say they come very close to meeting their claim.
You can't fix stupid....however ignorance can be cured through education!
