...won't see 1000 rounds...."
Bad idea and bad preparation. There's way more good defensive shotguns out there than good defensive shotgunners.
The shotgun is not A Magic Amulet, shielding one from evil by its mere presence. WE have to become effective to make our shotguns effective.
Go shoot yours. Clays, starlings, landfill rats,steel plates, whatever. Run that round count up until it's a body part and not just a tool you're holding.
Install some wear marks and see how well it responds and how lightning fast it destroys that which you want so.
Mindset, skillset, then toolset.
BTW, most top instructors urge us to put at least 200 rounds (The Ayoob Test) through a prospective defensive tool before posting it as such.
