Beretta A400 EXTREME Unico( mag ext.)

Gents
Interested to know how many 2 3/4" and 3.5 shells can you put to the A400 Extreme.
Also needs some info on how to remove the B-Lock mag cap on this particular model, possibly to add a mag extension.
According to Briley which sells mag extension for the A 400, is just to remove the B-Lock system to access the threads. but how?
Kindly share your experience and knowhow on this, unfortunately I dont have the gun yet, but wants to make sure that in can be done.
Thanks

I'm sorry but I don't see the correlation of your post to my inquiries. Thanks

Sorry about that, I had watched the video but I think pasted the next video link by mistake. Does this link make more sense

No worries , I saw those videos, but nobody mentioned the factory mag capacity and can't find a vid about installation for Briley mag ext, especially the A 400 comes with a B-Lock system.

My a-400 xcel came out of the box 1+2 for total of 3. Now I'm sure there might be a plug in there but I have never checked since it is what I hunt with and Ontario we have a 3 shell limit.

A400 extreme can fit (3) 3 1/2 shells without the plug. And yes they do make extended tube mags for them.
