M1 Super 90 question

[trackstar55]

I have a Benelli M1 Super 90 with the pistol grip stock and 18.5" barrel. I just acquired a +2 extension for it. Is it legal to install it or do I have to have the standard stock on it?

I am more of a rifle man and know nothing of the ATF's view on shotguns.

Another reason I ask is that I am going to the INDY gun show this week and if I plan on selling it, I don't want to be walking around with a non-compliant ATF setup. I dont want to be pulled into a side room and given the water boarding treatment by some undercover agent.

I am thinking the gun would be worth more with the +2 installed vs. selling it separately. Maybe I should just hold onto the +2 in case I get the M1 bug again someday.

I am going to the gun show tomorrow and need an answer please?

I guess my M51219X is a post ban then.

Gundoc,
Do you have a similiar breakdown for the M3?
