Ok I have a KWA M93R and it worked fine for a month… or less and then the trigger stoped working (not always just some times) and I have narrowed it down to the hammer sometimes jams… idk how (thats why im asking) but when im shooting with out a mag the hammer will always work but then when I put a mag in the hammer some of the time wont drop when I pull the trigger. I can get the hammer to drop by pushing on it will just a little stick or somthing but nearly no force is required to get the gun to fire after the hammer jams (some time shaking the gun is enugh) I am using propain and silicon that came with the ASI propain addaptor. O and taking the mag out doesnt drop the hammer after a hammer jam.
