I've ended up with a beater Mossy 835 Ulti Mag VR 24" barrel that I want to use as a Home defense gun. I see where Mossberg doesn't make a barrel under 24" for this gun because it's predominantly a turkey gun. It has a full BB lead and steel choke in it. What shot is able to be fired through it, and what's the likelihood of someone cutting it down to 19" or so. what happens if the choke tube is cut out of it. I don't know much about shotguns but I live in a really small place with not much clearance in doorways and hallways.
