Snowjob,
I understand where you and 355 are coming from, but I think any realistic threat that you'll need to shoot at someone farther than 10 yards or need more firepower is extremely slim. Additionally, in the senario where you would need an M4 (riots, SHTF, etc), most likely you would have the extra couple seconds to grab it out of your safe, versus having to have it next to your bed.
The advantage of the shotgun is so great for 99.9% of realistic senarios, IMHO.
