I'm running my KSC G19 on propane at the moment and it won't stop spitting gas. I have upgraded it with a metal slide and the appropriate recoil spring. It is being fired upright, not gangster style... It will fire okay(but with very weak recoil) for about 10 rnds. After, it will start spitting gas from the ejection port and sometimes from the barrel. The blowback is very weak and it sometimes doesn't cycle properly to disengage the gas and the thing ends up venting completely. I've tried oiling it but it will still continue to vent. The most recent thing I've done is oil and grease the rails and hammer assembly. Could over oiling have caused this? I'm also suspicious about the mag itself and possibly the gas valve. It is sometimes a bit sticky and I sometimes hear some rubber squeaking when the valve is pressed. Anyone have these problems before?
