Does anyone know how to downgrade a KWC CO2 M1911A1?
It's running at 400 fps at the moment, but I need it below 350 for my site.
Any idea if/where I can get "low-flow" valves for the magazines?

trim down the float valve spring.

Forgot I had this here.
Apparently, RA tech make an adjustable valve that can be fitted in the blowback assembly (I think it's like an NPAS). I'm waiting for delivery.
