Good combat shotguns aren't rare. Any of the Big Four will do well in trained, cool hands. The Italian guns are probably close, also.
I prefer the 870. But with similar training and familiarity with the others, I'd expect similar results, tho I may have to replace or fix some of the others more often. Moot point, even the alloy framed ones will handle an amazing number of rounds if maintained.
Neglect and abuse kill most shotguns, not use.
Dfaris, my old prison had all the spare parts for an inventory of over 30 870s fitting into a shell box except for a stock and forearm. We had a couple firing pins,bead sights, a mag spring or two and a spare bolt.
