Home clearing and CQB with a bullpup configuration rifle or shotgun is a glorious pleasure. It's amazing. You can open doors and move stuff around with one hand, all while keeping your weapon pointed at where you're looking and working.
I love it. But...
FOR ME PERSONALLY...
For home-defense, I would stick with the most simple, rugged (not to mention, CHEAP) solution:
A full length pump-action shotgun with an 18.5" barrel and magazine tube extension.
> I would get one that is chambered for 3-inch shotshell (usually identifiable by "magnum" or simply 3" / 3-inch engraved on the receiver or in the model name.
> I would load it with 2 and 3/4 inch 00 buck for maximum ammo capacity and to cut down some of the recoil.
> I would store it in the home with a full magazine but with no shell in the chamber.
> If you're new to pump-action shotguns, I would spend 60 seconds in constant dry-fire and pump-cycling every day for 2 straight weeks. Practice moving all around the house while clicking on an empty chamber and RACKING that pump action as fast as you can after every hollow 'click.'
Do this while sweeping the shotgun from side to side, while pointing it down, while pointing it up, and from several different body positions.
> If you build solid pump-action muscle memory, you can mitigate almost all the drawbacks of using a pump over a semi-auto. (In my youth, I could shoot my pump shotgun almost as fast as any semi-auto! Especially when target acquisition was necessary for both shooters).
OPTIONAL:
> Consider getting more cushiony rubber or gel butt-pad. Most detach and attach with only two simply phillips-head screws.
> Consider cutting 1" of wood off your buttstock and re-attaching the butt-pad, if yours does have a wooden stock. (This makes the shotgun more maneuverable in the home).
> Consider adding a butt-stock shell wallet to your shotgun. (7 rounds is plenty for home defense, but you'll never regret having 5 more). (I like butt-stock wallets over sling bandoliers because they keep the weight back at your shoulder: especially helpful in a front-heavy shotgun that uses a plastic/polymer stock/forearm.)
MODELS:
The two most common classic pump models (and the ones most produced / least expensive) will be the Remington 870, Winchester SXP, or the Mossberg 500. But the Benelli Nova is one sweet, gorgeous shotgun as well.
So: if you've been in the market for a shotgun, I hope this helps you.
