Airsoft Canada - View Single Post - KJW G27 low fps and puff of gas from behind

I have a KJW G27 upgraded with Guarder Recoil spring and rod, knocker spring.
I have low fps compared with my other pistols and the first shots always a puff of gas come out from the back.

I tried to swap the mag valve with one of a WE mag but nothing change. This valve works well in my WE G19 but in my G27 not.
It seems that my G27 has low knocker strenght but I inspected more times the trigger knocker parts and everything seems ok.
What can I do?
