My vote is for the mossberg 835. Basically a beefier 500. Aluminum receiver saves a little weight, safety is ergonomic and ambidextrous, user replaceable ejector (870 is riveted), gloves don’t get pinched while you load it as the shell elevator stays out of the way, lots of barrel options as it shares the mag tube with the 590a1. You can run the bird barrel and stock tube cap in the field and swap to a cylinder bore barrel and choate extension for bedside duty in under a minute.
