KJW G23 trouble
I have a KJW Glock 23 Gas Blow Back pistol. I had it for about a month or so, and it was only used in one game with less than 100 rounds put through it. About a week after it was used, I loaded and fired it, however after the third shot it made a "Click" noise and would not re-cock. The part that strikes the gas valve on the magazine does not seem to be resetting properly, and I think I may need to replace the entire trigger assembly. The 30 day manufacturers warranty has expired, and there is no other warranty on it. I did as much research as I could, and I cannot find any way to fix it myself. I would prefer to be able to fix it or have someone fix it without needing to mail it out.
The GBB was purchased from a shop locally which carries no warranty on the product, as it is a paintball shop, and the employees there don't know how to repair airsoft guns. |

Either:
1). Your disconnector (Part #45) is not working properly. Check to see if it's seated properly and makes contact with the valve knocker. You can tell if it's function by holding the disconnect lever (Part #45) when you manually ready the hammer to a fire ready position. If the Valve knocker pulls back while you are hold the lever down, it's working if not then it might be the problem. 2). The pins holding everything (the hammer assembly) are not holding everything in place and maybe dislodged. Re-seat them. 3). Check if everything is still not broken or worn in your hammer assembly. The valve knocker is one of those parts that are prone to fail because of their function. 4). Your knocker spring (part # 53-A) is causing the Valve knocker (the part that strikes the magazine) to be unseated properly. If it's not on right, It can cause the valve knocker to misalign in conjunction with the other hammer parts. And thus can cause the problem described above. I can't diagnose the problem without seeing it. send her to me

Thanks for the quick reply! How would I go about re-seating the spring without disassembling the trigger assembly? I'd like to avoid taking apart the lower half of the gun, if possible.

The spring is located inside of the hammer assembly. I'm afraid you will have to disassemble the hammer mechanism to access is properly.
Remove the slide and manually cock the hammer. Hold down the lever beside the hammer while you cock it. That's your disconnect lever. It should set your valve knocker into the fire ready position. If this doesn't happen, then you've found the problem. The fix is open up your gun and see if the valve knocker is making contact with the nub on the lever. if it doesn't, then just make sure that it does. Does the gun fully cycle with your hammer up? If it does then the hammer IS recocking.

Everything else functions perfectly. I have manually cocked it, however when manually cocked the valve knocker doesn't reset the way it does when cocked with the slide. Just after the gun stopped working, the trigger seemed to be jammed up and it kept getting stuck, but un-jammed again shortly after. I have no idea about how to disassemble the lower portions of the gun, or how to put it back together again, regardless of how much research I have done on how to do it. I guess i'm not very mechanically inclined.
Edit: When the lever is held down when cocking, the valve knocker is set into the proper firing position. Last edited by spd116; May 18th, 2012 at 20:07.. |

Also, the gun does not fire at all. It will just "Click" and release a small amount of gas. The weapon will not cycle, and will not fire a BB.

Are holding your Disconnect lever down when you manually cock it? If don't hold it down, the valve knocker wont move. But if you do it should set the knocker in the ready to fire position.
photo copy.JPG Also, if your trigger get's stuck, then there is something blocking the trigger bar from returning the trigger. Most likely it's the the contact point. Again, I can't help much if I can't see it. Here's an disassembly Disassemble KJW G23 Receiver - YouTube ITs most like that the other spring Part 53b is not hooked on properly.

The trigger is no longer getting stuck. And when I manually cock it while holding the disconnect lever down, it sets the valve knocker into the position it is supposed to be in. All the pieces I can see through the clear frame look to be where they are supposed to be, but I cannot see under the hammer assembly. And thanks for the video - It will most likely come in handy soon.

yes it wont fire because the knocker is not hitting the valve because its resting battery and thus wont cycle properly.
You need to open your gun and make sure that everything is seated properly.

Okay. Thanks for the help, but I doubt I'll be able to put it back together or not lose anything when taking it apart.

Ok. Now you can rule out that there is nothing wrong with the hammer assembly. The problem is the in the contact point between the lever and the slide. The slide needs to push down on the lever in order to engage it.
Rack the slide and then check to see if the knocker is in the fire ready position.

The replies are fast enough for me. And yes, the valve knocker is set into the correct position when cocking with the slide; The lever is being pushed down by the slide. My theory lies with the knocker spring being unseated or damaged - It seems like it just doesn't have enough force to open the magazine's gas valve. (It isn't the magazine, the amount of gas in it or the gas being used - I have tried three different magazines, some containing lower amounts of gas than others, and different brands of gas.)

Well if that's the case, just buy a new hammer spring. a 150% strength should give you the strike you need and keep it in place. Buy a new valve knocker while your at.
I would still open her up though. Just see what the cause of it is.

I'd like to open it up, but I don't think I'd be able to. I suck at these things... Takes me forever to do, and I always lose those little important pieces along the way.
