Nothing there I would consider paying even an extra 100 bucks for except the larger magazine. I’ve had my 500 for 30 years, put it through a lot use and abuse and there not mark on the trigger guard or anywhere else. It shoots just as hard and accurate as a 590.
Indeed, but you likely have not roped out of a hovering Helo, parachuted and crawled through swamp, jungle desert or woodland doing combat rolls and IMT, dove into it on concrete rubble or used it to break windows or doors or wear a bayonet or ....etc.
But I hear you.
You would be amazed at what issue weapons and gear go through.
