Ahhhh yes. The golden pumps of pumps... the sear of shotguns, the venerable 870. I would say, as long as there isnt any mechanical defects (failure to fire, rack, slide, or otherwise hold a pattern/shoot), I would go with it. I still have my 3 since 1992. Been in the mud, salt water, marshes/swamps, uplands and forests, and they ALL still run strong.
