I have a little dilemma in my hands and i was wondering if you folks can shine some light on it.

The GBB is a Army Glock 17 has a full metal slide and is running on propane.

The gun is fairly new and after firing a total of about 8-9 mags it started to dump all the gas on the pull of the trigger, the slide would state stationary while the gas would escape though the barrel in a cloud of gas:?. I had mad a mistake by lubing only with the light weight oil supplied with the propane adapter for the first 9 mags.

after talking to CNDstalker i went out and brought some 10wt silicone shock oil. I stripped the gun, wiped off the old oil and appiled the new in needed areas like the frame rail, trigger mech and the hammer mech as told and working that in as well (possibility that hammer is malfunctioning). After doing that i fired a mag and it was great but i noticed the power in the kick was weaker in feel then before and near the end the mag had dumped the gas again.

Then a day after a leak starts up at the fill valve.

could all these problems be caused by a bad mag? or something else. The mag was treated well and was lubed. It is also fairly new as well.

problems in short
-sluggish blowback
-gas dump

any help is appreciated. :?
