If you need a slug gun for shotgun only zones, pick a 20 gauge or a 12 set up for reduced recoil and use a rifled barrel or rifle choke for real accuracy with slugs. I prefer a gas operated semi or a heavier pump because they soak up recoil better than lightweight guns, and a good recoil pad plus reduced power loads keeps your shoulder happy. Zero the gun at the distances you expect to shoot and practice from the positions you hunt so you know your point of impact, you’ll get effective hits without feeling like you were punched
