LE/civilian.
My agency issues bare basic 870s (mine's an express) along with our take home rides. No racks installed, and no mods to guns allowed. As I'm a short dude with a barrel chest and t-rex arms, the 14" LOP is a no-go, so it just sits in the trunk.
If I want a guage, I take my rifle-sighted M1S90 w/ Urbino stock, but lately it's been just the AR, mostly due to hauling the long gun(s) in and out of the house each shift. Been wanting a SF foreend, but new ones are no longer available.
I've been following the 1301 thread with great interest.
My other thought is to buy a Mossberg Shockwave, SBS it, and add Magpul furniture/light/XSBD for a work gun.
I have a good stock of Federal LE OO/slugs, but I want to pattern some #1B .
