Re: Shotguns for home defense... need reccomendations. A shorter barrel = a wider pattern. Even 00, or #4 buck is too large for 'urban/indoor' use. #6 birdshot can have a pretty nasty effect without the danger of 'getting' your neighbor. If I remember correctly 00 buck is approximately the same size as a .22. I once accidentally fired a .22 indoors(yeah, I know, stupid, Stupid, STUPID!), it went through THREE walls and kept going! You must deal with a VERY determined class of felons. Maybe you have some personal experience. But my thinking is that unless said felon is to 'high' to fear ANYTHING, or a paid hit man intent on achieving a goal, the sound of a pump shotgun being readied will most likely have them exiting the premises post haste. If the shotgun is for home protection, I advise keeping it loaded and within reach of your bed at all times. An unloaded gun is nothing more than a blunt instrument. If there are children in the house, there should not be a gun there. The two are mutually exclusive until the children are old enough to be trained in the use of firearms. Just my opinion. YMMV.
