KJW P226
 

having taken my P226 apart to investigate a gas leak i cant fit a part back in...

Parts 8 and 9...

I dont know which area of the reciver they go into (thanks to the bad angle of the manual)

If you do know, please mark it on this image

Put the loading nozzle (#12) back into the blowback engine cage (#3). Then, follow this picture.

The the spring guide (#8) will want to stick out of the #3, be sure you use a small screw driver to push it into the cage while you're putting the cage back into the frame. Otherwise, the #8 will prevent you from getting #3 back into the frame properly.

THANK YOU :D:D:

seems so simple now!

While we are here, the reason i took it apart was that after 2 shots, i lost pressue and the slide would not cycle. what would cause this? ive used two different mags with summer gas...

Check your loading nozzle and the bits inside the loading nozzle for damage. Could be something as small as a hairline crack.

This might be a silly question, but what gas are you using in it. That sounds exactly like what happens to my KJW M9 when I use duster gas instead of propane.

Summer aka, green gas.

Do you think changing it would make a difference?

No. Green gas and propane are the same thing. I was asking just by the odd chance that you were perhaps running duster gas (HFC 134A) instead, because your gun is made to run on green gas / propane. I tried 134 gas in my KJW M9 just to see what it would do, and it seemed to do the same as you described.

Perhaps it's the outlet valve on the magazine (part 76) that's the problem. Is it moving smoothly in and out when the mag is empty?

past works fine. taking apart again to check all the seals.

Only damage ive found so far is this:

the little bit of silver is shorn off metal.

This is a second hander so i was expecting problems...

It's not really cold where you're testing the gun, is it? And you're loading enough gas into the mag? Not using an almost empty can or anything? Is part #30 intact? What does the gun do when you fire it, does it do a whimpy little "burp" fire?

Gun test is indoors about 18-20*c

part 30 is intact.

Two proper shots with the action cycling (quite loud thank to the metal slide), then the third shot at alot less power. then nothing. all gas expended with those shots.

Can is brand new

Wait, all gas expanded within 3 shots? It must be venting gas like crazy then. Are you sure parts 11-15 are intact?

Ok... so the gun was bought used. I'm just curious about the mag now.

I was told that TM M9 mags worked with KJW M9s, so I bought one. The thing fits and seats perfectly, but does the exact same thing as yours. I get 2 normal shots with full blowback, 3rd shot has almost no power, ad the gas just vents out. This may not be the case, but perhaps it's not the gun, but an incompatible mag? For kicks, take a pic of the fill valve on the mag and post just so we can see. TM and KJ have different fill valves. Maybe that's the problem.

Just throwing out ideas here

mags are KJW, they have the stamp for it on the bottom.

I'm going to try using blu tac to fill any areas that i think leak and see what happens... at least that way i can see which part leaks so i can repair it.


Certain that these parts are intact: 11 to 15 removed, checked and replaced without complaint. This was after the problems. At the moment i'm looking at the hop unit since there is visable damage there.

Yes, all gas used in three shots. exactly in the way Crunchmeister described it

On my M9 with the TM mag, if I press the base of the TM mag up into the gun and hold it there while I shoot, I tend to be able to get about 15 shots or so before the gas vents off. I've already determined that's because the KJW mag is about 2mm taller than the TM, so I think the valve and firing pin probably don't mate up right. I know it's a mag issue for me.

Of course, I can't say for sure it's your mag, but from my meager understanding of how GBB guns work and your symptoms, that's what it leads me to believe.

contacted the person i got it off, and apparently he had the same issue since the start.

i'm going to use more powerfull gas and see if this improves
