Any shotgunners out there?

[cycloneshooter]

I am looking to put together a lightweight, short barreled, 20ga turkey, coyote, home defense type firearm.
I was pretty set on a Remington 1100 with a 21 inch vent rib barrel, but just learned those barrels have fixed chokes.
Looking for something with screw in choke tubes in order to stick a super full or turkey choke in.

Anybody know what the shortest length 20ga adjustable choke barrels available are?

I like semi auto, I like Remington, but I am open to any other ideas as well.

Barrels can have chokes installed on them at companies like Brileys, Carlson, Trulock, etc. If you plan on using steel shot, then I would advise aftermarket chokes.
