What are you thinking of using, and where are you going to get gas more powerful than green gas / propane? CO2 might be an option, but how will you fill mags with that?

[The Saint]

CO2 is not an option, please don't even suggest that. Normal airsoft gas pistol mags are not rated for CO2.

Burger, just to dress Chunch's repeated concern, is the mag locking in positively?

In order for the mag to vent massive amount of gas, there has to be one of two problem. One, the valve has to be malfunctioning in someway and closing improperly. It doesn't sound like that's it right now. Two, the internal striker/hammer is not resetting properly/promptly during the slide's cycle.

I'll dismatle the handle completly and investigate the hammer system. however if that does not resolve the issue, i will be taking the former owners advice and using predator gas

Yeah, I wasn't quite sure about that, hence the "might" in my reply.

But even though I don't know squat about the internals of GBB guns, I tend to think that it's either the mag or the striker. That would make sense. However, often things don't seem to make sense when something isn't working right.

It's too bad you don't have another mag to test the gun with, Greasel. That would at least eliminate the mag as the culprit.

Well, at least you're honest about it...

[Crunchmeister]

Yeah, I'm an airsoft noob and quite inexperienced with the techical side of the guns, but I tend to learn things quickly on my own. I've been doing repairs and maintenance on CO2 pellet / BB pistols for myself and friends for 20 years or so (although not consistently). I taught myself how to do that too. However, I realize that there's a big difference in GBB airsoft and pellet gun internals. That's why I haven't had the balls to rip apart the internals of my M9 to install the 190% trigger spring I've had kicking around here for almost 2 months.

But troubleshooting is troubleshooting. You observe the problem and find possible causes, then try to either confirm or eliminate them as the source of the problem. And since the gun seems to be in perfect order (from what the OP says) in all other areas, I would focus on the mag and striker first before moving on to other parts. Also, since he's having the identical symptoms that I had using the TM mag in my M9 (and I know it's because the mag sits 2mm too low), then it would seem like it's a reasonable place to start.

[Greasel_burger]

mags are not the issue, i'm sure of this since ive tested the spare.

leaves either the pistol (and that would have to leak pretty badly) or the trigger. and since the mags empty fast, i'm thinking trigger

[The Saint]

What do you mean by the trigger?

[Styrak]

The trigger has nothing to do with it, it would be the gas hammer, if anything.

[Greasel_burger]

my bad, i was refering to the entire system of the trigger, hammer and handle

[Crunchmeister]

Ok, I didn't realize you had 2 mags. If it does the same with both, it's definitely the gun.

I'm not sure where the part is in particular on the exploded diagram, but check that striker / gas hammer (whatever it's called) first. There should be some kind of spring return on it, so that when it hits the valve and opens it, it returns to not keep the mag valve open. It's quite possible that this part is not returning easily enough (too much spring tension, broken or missing spring, or somehow just striking too hard, causing far too much gas to be released.

But it sounds like you're on the right track now with troubleshooting.
