Hey JMD~I'll let others chime-in on this, but my understanding is that for a defensive gun (not wildlife) you're better off with 00 Buck vs. slugs. Pretty sure it's what LE/military use, anyone with first-hand experience care to chime in? I've certainly read accounts of 590s in combat, if memory serves..no slugs used. As for chokes, maybe it's your experience level with shotguns...but unlike rifles, you change the effectiveness/range/pattern using choke tubes, whether you hunt or not. You don't need/want them with slug use, but as soon as there are multiple projectiles with every pull of the trigger, the barrel's choke plays into the end result. Yours is most likely NO choke (=CYL, or cylinder bore) so knowing how that patterns plays into it's effectiveness. True, the smaller the shot size...the more a tighter choke impacts the patterns. Still, choke tubes are something to consider if you're wanting that level of control. Hunters know (or should) to pattern their guns before hunting. It's the only way to guess how many pellets of a given size are likely to hit a target OF a given size at a given distance. Leave that to chance, and you're rolling the dice. I proved this to someone a year or so back, we set-up a gatorade bottle at about 30' away, CYL bore shotgun, 20" barrel, 00 Buck. 3 shots/zero hits. lol Just too open a pattern, even at that distance. Granted, small target...but you get my meaning. I'd missed a few groundhogs using 00 buck at about that distance, decided to pattern the gun. After the gatorade bottle test, out came a pc. of cardboard to see what was happening. I switched to #4 shot.
A wallhanger/conversation piece~lots of merit in that I suppose, but not being fairly proficient with it sort of limits how effective a defensive tool it might be if required. I can barely go a week without feeling the recoil of a shotgun, or rearranging various household items. (if not shooting clays that is

)
