Are you able to comment on how the magazine tube is blocked and what the capacity is?

Thanks!

The JM Pro holds 4rds of 2 3/4". It is blocked with a white plastic bushing that is roughly 2" in length. There is another plastic bushing on the other end of the tube that is crimped in place.

And what do you think the best way to remove that plastic stopper? Hypothetically speaking of course.

hypothetically you'll need a different mag tube spring to ensure proper feeding of the gun...

Well, this is a competition gun. Quad loading is a breeze with this gun!

Thanks for the detailed reply, may be easier to screw on a different tube to get the maximum legal capacity rather than try to modify the existing one.

An extension from a 930 with wave washer works. It does change the balance slightly after blocking it to the legal limit.

What extension length is that? +2 I’m guessing?

I would also love to know what extension you're using and from where you got it! I noticed Wolverine Supplies carries multiple magazine tube extension options for 930s but I would like to know exactly which one will allow for just under six 3 inch shells (ie. five 3" shotshells) to be loaded so I can stay legal.
