Stevens 320 20ga mag tube extension?

[PaulW]

Picked up the security version, is there a +2 mag extension I could use on this? Google says Winchester 1300, and 870 ones will work. Does anyone have a definitive answer?

Nobody?

Can't say for certain, but since the Stevens 320 is a carbon copy of the Winchester 1300 I'd feel safe in saying the one for it would probably fit.

The barrel nut just has such a coarse thread, I'm just not sure if it will be the same?

See the comments/reviews tab, looks like it's a perfect fit for the Stevens 320's so I'd say it's a safe bet that any for a Winchester 1300 would work.
