My M9 PTP has been giving me a lot of troubles lately and I have been working on it hoping to get somewhere, but nothing. It will get about 6 or 7 shots off and then nothing. The blowback is slow and weak. It has very low power and doesn't have the nice clack sound anymore, it's more of a pop. I have replaced the hop up bucking, cylinder, cylinder return spirings, piston ring, and blowback housing. So none of those are the problems (hopefully). I've also noticed that when you pull back the slide it feels rough and like there's more friction than normal. The recoil spring also seems really tight of the rod and also has some friction. If it helps, it has been fed propane its entire life. I know very well how to take care of gbbs so it's been cleaned, lubed, and properly cared for. But I'm out of ideas on what's happening here. Any ideas guys?

Try cleaning your gun's rails, then use a lightweight 20 wt silicon oil. You can find this at any RC hobby store. Maybe it is your magazine-- make sure it is gassed up fully, and maybe it's the pressure in your can of propane. Try a new can of green gas and see if it yields different results. If you can't access green gas, buy a new can of propane- it could just be the pressure. Be sure to lube your propane, and fill your magazine on 5 second intervals with 3 seconds lapse. Try that, if still nothing, maybe get an RMA and sent it out to KWA...

Rails are cleaned, I used the liquid, not sprayed silicon, I have no access to GG, have a new can of propane, and I have 2 brand new mags. The gun is 3ish years old so no warranty. I have a lot of experience with gbbs, I just have no idea whats happening here.

Are you sure you are using an M9 PTP and not a different/ older model of the M9? Perhaps you're using M9 PTP mags in a non M9 PTP gun... (you've got the M9 Standard, M9 HVY, M9BR, or the M9V?)

If it's not that, my diagnosis is that it's either the valve knocker hitting the gas valve on the magazine, or the jet nozzle-- maybe it's cracked or you may need a new jet nozzle inside.

Try a drop of silicone on the gas release valve on the mag and see if that helps.

I know it's the PTP. I'll take it apart tomorrow and look at the jet nozzle. Are the jet nozzles the same on all NS2s? I have an extra one from my M11A1, I'll just put that in the M9 if it fits.

The jet nozzle is the same for all the pistols. Not sure about SMGs though.... Here's the link:

Old jet nozzle seemed fine, nevertheless I got a new one from the Pro Shop. No improvement whatsoever on performance. I'm completely stumped. I've done everything other than completely replacing all the guts. Scraping it and getting a new one is out of the question, this was my first gbb and first KWA so it must be saved.

P.S. Record warm days where I live so I decided to shoot it. Still the same problems but I noticed the slide gets cold and a lot of condensation on the slide. Mean anything?

I've never experienced condensation from firing the M9. If the slide gets cold, that means the gas is escaping from the jet nozzle (part 320) completely, or the seal is not fitting correctly... if buying a new jet nozzle doesn't sound like it will solve the problem, I would just suggest getting an RMA number and sending it in to KWA for repair.
