Gas filling question
Posted 09 April 2009 - 12:35 AM
I just purchased my first GBB. The KWA M9 PTP is a fantastic gun, but I need to know how I can tell when the mag is filled with gas. I'm using propane in case anyone is wondering. Are there any tips you guys can give me to make sure I'm getting a fully filled mag?
PS-Its my goal to own 1 of every PTP model that they make. Thats how impressed I am with the M9 PTP.

Really? I tried filling my mag for 4 seconds and I barely got 10 shots out of it. The first 5 were at full power with a very noticeable drop in power on the 6th -10th shots. The last shot wouldn't even cycle the slide.
From my tests, I've got to fill my mag for 80 seconds, with 10 seconds between each 20 second fill. This is the only way I'm getting a full mag of shooting at full power. I just bought the can of propane so I know its almost full.
As far as the mag hissing, it doesn't make a sound when filling. When I remove the adaptor from the mags fill valve it does spit. Unfortunately, it does this after every 20 second fill, even the first. I thought when I heard this, after the first 20 second fill, that the spit meant it was full. But after only 20 seconds of filling the mag, I'm only getting 15 shots. The last 3 are very low velocity and the 15th shot won't cycle the slide.

is the hissing effect the same when using green gas?

1) I made sure that I was properly aligning the propane adapter to the nozzle in the magazine. With an angle between them they will not fill as effectively (I've found).
2) I loosened the adaptor on the propane tank a little bit. When I first got the gun and went to fill it up, I screwed the adaptor all the way on, as far as I could, and the mag just wouldn't fill up. So, I decided to try loosening the adaptor to give it a little more room to travel, and my mags filled great.
Give those a try. Hope they help!
