Is adding the MXT extension tube to a 1301 legal, it adds two rounds which would make the capacity 6+1, does the +1 count as a round or is it just what you can fit in the tube which would be 6. Want to add a flash light and it seems like the MXT extension is the easiest way to get there. 
 

Thanks,

Marty

 

You are limited to 6 in the tube.  The one in the chamber doesn't count. 

Thank you

Now I’m getting myself even more confused.

The Beretta 1301 Tactical is a gas-operated, semi-automatic 12 gauge chambered for 2¾- and 3-inch shells. It has a tubular magazine with a 5+1 capacity using 2¾-inch shells (or 4+1 with 3-inch shells).

with the extension tube and 2 3/4 inch shells I’m over the 6 round limit, with 3 inch shells I’m not.

what shell size is taken into consideration when determine magazine size in nj?

My god, all I want to do is put a light on it.  

If it can hold and function with more than 6x  2 3/4" rounds in the tube, it's not legal.

Since the 1301 Tactical is a 5+1 already, you could get the +1 extension, not the +2.

Was there a plug In the tube to limit the capacity before you put the extension on. 

If the whole purpose is to mount a light, then have you looked at the Steiner Mk7 Battle Beretta 1301 LED Tactical Shotgun Light? It looks like it replaces the end cap.

Yes, there was a plug that limited it to two rounds. Took it out.

I will look for it.

Thanks, this on looks promising.  

Just my luck, Midway lists it as discontinued, and not available anywhere I can find.  

Put the longest extension on that you want, then epoxy a wooden dowel in the end to limit the capacity to (6) 2.75" shells (not quite 7), then (6) 3" shells should fit.
