kp-07 co2 1911 venting issue!
 

I just bought a kjw kp07 co2. I fired 1 full mag with without a problem but now any subsequent co2 cartridges that I put in the mag vent fully. I pull the trigger, hammer strikes the valve, slide comes back about a half inch, and all the gas vents! It is brand new. I took it out of the box, disassembled and lubed it but now it is venting! Any thoughts on a fix?

Sounds like your nozzle has either cracked, OR the outer barrel is jamming itself against the slide (this is a common problem with KJW's Hi-Capa clones.)
