My preferred semi auto fighting gun would probably look something like this:
Tromix 12” internally threaded for chokes or the tromix integrally suppressed S12
-when it comes to SBS guns the saiga has a huge advantage in that it loses none of it round capacity. What other 8” shotgun have you seen with a capacity of 20(+1)? Or even 8(+1) my preferred mag capacity.
-the suppressed tromix was a one off gun I believe. I tried to find pics but the ones Tony had are no longer up. Reports were that it was quite enough to be fired (00 buckshot) indoors with out hearing protection. I lust after that S12 and would love to own one.
Stock of one’s choice, on a SBS I like a folder of some variety. I have yet to settle on what stock is my favorite though.
Tri-rail fore grip
Sure fire light
Tango Down VFG
HK sights w/ tritium insert front post
JTE Mag well (mags drop free and are straight insertion as opposed to rock and lock, reloads are much faster)

8 round sure fire magazines. 8 rounds IMHO is the best balance between capacity and size. I should note that I might well be won over by the forth coming MD double stack mags. Time will tell.
Extended mag release
Tabbed and notched safety lever (or possibly left side sliding safety)
Last round bolt hold open and bolt release. (when these become widely available they will really enhance the S12)

Gunfixer gas plug or lever that allows gas setting to be changed by hand
Tromix firing pin
