Recoil should be low with the right spring set-up.
It's not lost much weight because the metal is very thin, it's 250g VS 252g on a standard one according to that image I found. The front section with the concentric bands is solid metal, ie way more metal up front than on other pistons.

I'm having second thoughts about using the Ox spring, I think it could be a bit brutal.
