So as most people know the KJW 1911 is horrid in gas efficiency. So personally Ive opted to use CO2 mags.

Ive shimmed the gas routers, and attempted to replace the piston head with a nineball DYNA but seemed like it did not help at all (Yes I tried both Orings), for some reason the stock piston head actually works better.

It seems to be functioning decently but I still don't find the blowback quite satisfactory, and it seems to lose its kick rather quickly.

I was thinking to replace the BBU with a lightweight one, but was wondering could those lightweight bbu's withstand CO2?
