[Marauder]

My favorite is the Remington 870 slide-action. You can buy mag extensions to up to 10 rounds, counting one in the hole. I sawed mine off to 18" (min. legal barrel length), and added a pistol-grip buttstock. Min legal overall length is 26" overall, so it's well within the limit.

Leave the chamber empty; if you find a burglar busily loading up your stuff, you will have fun watching him load up his pants when you rack the slide. But don't laugh too hard - he may be armed as well, so be ready to introduce him to his Maker.

You don't need the chamber empty to cycle the loader.

The sound of a round being chambered in a M1911 .45 auto is good too.
