I'm still having this issue with my P232. It seems like it's not releasing enough gas to cycle fully, so with each trigger pull, it only does one of the two actions controlled by the rocket valve.
If there's a BB in the chamber it will fire the BB and the slide will only kick back weakly 5mm or so. If there's no BB in the chamber, then it will cycle back, but not enough to trip the trigger release, and so will keep blowing back until another BB is chambered and fire that with no blowback.
Basically it shoots every two trigger pulls. One pull chambers a BB and might fire it, the next fires it for sure but doesn't chamber another, the next chambers, etc.
Like this (someone else's video, similar problem):
YouTube - KSC P230
It ends up working reliably only if manually charged every shot to ensure a round it in the chamber.
I thought using higher pressure gas (propane) might alleviate some of the problem, but it still does the same thing but now when empty, it blows back crisply enough to release from the trigger so that it isn't continually cycling. It doesn't solve the 'two trigger pulls' function though.
I noticed that my 232's firing pin doesn't stay down until unclipped by the slide movement like my KSC Glock, and am wondering if this is the problem. Can someone else confirm for me that when fired, the KSC P230/232 firing pin retracts by itself even if the slide doesn't blowback (ie, dry fired)? I can't think of anything else that could cause this problem at the moment. It seems like the blowback chamber and rocket valve are in good condition and functioning as designed.
