Victoria Reclassification of LA Shotguns

Victorians with LA shotguns are apparently going to get a letter next week informing of the reclassification from A to B of 5 round Shotguns and a list of their registered firearms to check off.
My standard Adler is registered as having a 4 round magazine, I guess they used the 3 1/2 " shell capacity.
Should I use this opportunity to bump it up to a 5 round capacity or just leave the dogs sleeping?
I mean it is technically correct.
What capacity are others Adlers registered as?

Yes its all true I have just been on the Vic Police website and the date set out for this change was yesterday the 1st of October. There seems to be some other changes to the general Licensing of firearms as well.
