Porting on Defensive/Tactical Shotguns - juice worth the squeeze?

Consensus among most shotgun shooters is that ports contribute very little to recoil reduction. Experts say that shotgun shells lack sufficient pressure to propel gases to velocity levels needed for the "jet effect". I have a ported barrel on a duck gun. I see it as a marketing gimmick. If a barrel had ports on the very end, i can see how they might reduce muzzle rise.

Many years ago, Lyman sold a gizmo called a Cutts Compensator, which accepted long choke tubes. The contraption had maybe 10 slits on each side. It did work as advertized and was popular with skeet shooters during the 1930s and 40s and lesser so iup through the early 50s. The thing was extremely loud. If you notice that some Thompsons have a knob on the end, you're looking at a version of the Cutts. I've fired shotguns and one Thompson with a Cutts. Now days a Cutts on a shotgn devalues it. For the last 50 years many have called them dog dicks.
