KWA USP Full Size (NS2) venting gas when fired

[Beefstew]

Hello, I just bought a brand new KWA USP last week and after a few hours of shooting in the range, it suddenly started to vent gas everytime I pull the trigger. I noticed too that after that problem started, the mags became cold to touch. This is my first time owning a GBB, especially a KWA pistol so I'm worried and also disappointed.

Any help would be appreciated.

could just be cold weather tho
and yes mags will get could after you shoot its cooldown from gas expansion
