KWA P226 PTP Mag issue

[sfours]

So I've received my PTP, test fired it, took it to a game, and I'm seeming to only get about 15-17 bb's per gas fill. The magazine holds 25, so I find this weird. I've removed the slide and lubed the rails, lubed the valve, and tried again with the same results. Wondering if anyone has any ideas on a possible solution?

Thanks in advance

Had a chance to test-fire a new M9 PTP... seems to have the same problem.
I didn't get a chance to experiment, but there is a trick that might work. I used this with a WE Luger that the owner was having similar issues with. Squirt a small amount (one-half to one second) worth of propane into the mag. Very gently, depress the valve with the mag held upright (and away from your face) until the mag starts to vent. The mag should grow cold. The instant it empties, release the valve, invert and fill the mag before it has a chance to warm up.
I've also used this trick with butane torches and lighters that were reluctant to fill. Another trick is to put the mag/torch/lighter in the freezer for five or ten minutes. As long as the receptical for the gas is colder than the source can, it should fill. The greater the temperature differential, the better it works.

I actually got it to work. Not sure what exactly fixed the mag but only thing that I have done differently was I left it with a full charge of gas over night. I'm thinking it may have reseated a seal that had a small leak.
Every other time I'd leave it with just enough gas for 1 or 2 shots. It may not have had enough gas to seat the seals properly. I also noted a large blow off of gas while test firing the night before I left it fully charged.

Thanks though, I think that may have worked with some of the butane lighters I threw out before.
