As has been mentioned....... the Kel-Tec KS7 Bullpup shotgun would fill the need very well.
It's more compact then any standard shotgun and unlike the Mossberg and Remington Shockwave type guns, the KS7 has a buttstock and recoil pad that allows fast, accurate shooting.
Carried on a sling it can be swung into action very fast.
26 inches long and an 18 1/2 inch barrel, which makes it legal everywhere.
Weighs 5.9 pounds unloaded.
Holds 7 2 3/4 inch shells or 6 3 inch Magnum shells.
Shoots slugs, buckshot, and birdshot very well.
The odd looking carry handle/sight actually works very well and there's no need to turn an electronic sight on or pop up iron sights.
If wanted you can buy a factory rail like the one for the KSG and mount any sight system.
The KS7 is the KSG, improved, and with the much simpler single magazine tube.
Any new gun bugs have been corrected and they WORK.
