I'm looking to get a shotgun primarily for HD and could use some suggestions. I don't expect to use it for hunting (not at this time although in the future some bird/waterfoul hunting is possible). The primary use would be HD. I'd prefer something more compact and easy to maneuver in tight confines like hallways, etc. What should I look for? Brand? What are those pistol grip shotguns like? Should I not even waste my time with those? I'd prefer something reasonably priced but I'm not looking for anything cheaply made so I'm open to spending more for something reliable and comfortable. And again, I'm not looking for anything ginormous like Jed Clampett would wield but rather, something smaller and more tactical. Thanks folks!
