So, Joey @Stihlbro mentioned he has been studying his 620P. I think studying is the most important thing a guy can do to understand the specifics and intricate details of any subject.

That said, I have been studying wakizashi as well. Specifically how the piston and case feeds the transfers.

I have been pondering this piston modification.

I think it will allow more charge to flow unrestricted to the transfers. Plus offer the benefit of a lighter piston and increase volume for fresh charge.

Can you explain how this will allow better flow? I can't see it from the pic.

It is hard to see and understand in 2 dimensional photographs.

The best I can explain it is - you can fit more stuff through a bigger hole. Think of a fire hose and a garden hose, both have 60psi of water behind the nozzle. The fire hose is larger, so it will move more water volume in a given ammount of time.

Garden hose would shoot it farther though, it's a give and take.

But I think this mod would be beneficial
