I received my KWA M9 PTP through a friend of mine as a hand me down and I should note that it's seen a lot of action with the use of propane over the past year. I do keep it well maintained and lubricated as often as I can and haven't had much problems. Now, I am starting to notice some issues with it. Just a week ago, I was shooting perfectly with it and the only issue was that I lost my fill valve o-rings for my mags, forcing me to stop playing until I got new o-rings. When I finally got my o-rings, I lubricated and placed them where they belonged, along with lubricating all of my mags since it has been a while. Now that I'm using green gas to test out my mags, I notice that my M9 PTP feels well under powered an and begin to think that the o-rings might have been a problem and not allow enough gas to go inside the mag. I try to use propane as well and realize that I was running into the same issue, but seemed that would run out of gas before the approximate 24 bb count and would strangely freeze up my gun. This has never happened before with propane. I also would like to mention that there's not enough power anymore to push the top slide back and lock it. Going back to green gas, I tried the magazine with my M93R and it worked properly as it should have, locked back, and I felt the hard kick that it should have, unlike my M9 PTP. I'm starting to realize that this may now be an issue of the gun itself, rather than the mag and would like some advice on possible problems and what I would need to do to resolve those issues. My last option would be to send it in to KWA for repairs as I want to do my best taking on the challenge myself.
