Help needed FNX 45

[ThisKillaDT]

I have been having some problems with my beloved FNX 45.

 

its not the cyber gun version, I think it is vfc, apologies if I am incorrect, had it a long time.

 

last game was running lovely then psssst, like its not venting or being struck correctly. 

 

Every trigger pull results in 10% of a normal sound of a trigger pull.

 

the gas isn’t coming through strong enough to shoot.

 

so I bought a cyber gun fnx 45 as spares in black, fancied a change and swapped the slides over, internal swaps also. 

 

The cyber gun one works great but my tan one doesn’t shoot any more.

 

anyone have a clue as to what could be the cause. I have stripped and checked it visually and can’t notice anything. Tried 6 different mags in it and always the same result.

 

any help would be appreciated
