I have 2, first a fairly basic H&K (Benelli) 121M. I did have tin wall tubes installed and it has been ported. Spare barrel carries a Tijicon Reflex sight
Next is a much modded Remington 1100. It were a straight rifled Hasting barrel to improve patterns, 10+1 Choate mag extension, and Speedfeed II stock that holds 4 more rounds.
Of course for a really serious problems there is the 1100 with the XRail holding 23 rounds...
