BeardyFalcon Posted April 26, 2021 Posted April 26, 2021 Hey guys! On the last trainig I was facing an issue with my M92 GBB form KJW. First 6-7 BB's were OK but then it stops shooting normally. It shoots once, then it doesn't load the next BB (Slide doesn't move fully) and the hammer is not cocked. But when I try to shoot again, it loads the BB and it shoots afterwards only once again. The M92 is with a CO2 mag. I have tried also a classic GG mag but no success. Same issue. It has been also cleaned, oiled with a silicon oil but that didn't helped too. Any ideas guys on this issue? I can show you later how it shoots by uploading a short video.
BeardyFalcon Posted April 30, 2021 Author Posted April 30, 2021 Here is a link for the video. It is not publicly visible vid. I don't know what is wrong with it ? Do you think I should change something? It was not cold and the mag is a CO2 version.
EDcase Posted April 30, 2021 Posted April 30, 2021 That's a tough one. It obviously looks like its running out of gas but I presume you used a full Co2 cartridge. Does the slide feel smooth when pulled back slowly? (anything catching?) Look for areas of metal wear to see if things are causing friction. If you have some silicone grease, put some on the gas vent of the magazine to help with the seal.
Daveoc33 Posted April 30, 2021 Posted April 30, 2021 +1 for friction on the slide. Or it could be a problem with the valve knocker - perhaps not resetting properly. If it's flapping around then the sping has got loose.

Well, it was indeed a new CO2 cartridge in the mag. When I'm pulling the slide, it goes smoothly in my hand with no problem. On 30/04/2021 at 15:03, Daveoc33 said: +1 for friction on the slide.

I have 2 mags so it doesn't look like issue with valves neither. As well as I have tried also 2 GG mags - same results. I will make more pictures of the pistol on Sunday as I'm going out today and getting back on Sat night.
EDcase Posted May 7, 2021 Posted May 7, 2021 Only thing I can think of is faulty/dirty output valve. (the one at the top which is hit by the pistol striker) Take it out and clean, inspect and oil it. (You'll need a valve tool but they're cheap) Other than that I can't think of anything. Maybe send to a tech?
BeardyFalcon Posted May 7, 2021 Author Posted May 7, 2021 I see that only the hammer is getting stuck a little when I'm loading the gun but that doesn't seem to be the problem as it shoots like 10 BB's with no issue and then it starts shooting weirdly.
BeardyFalcon Posted May 10, 2021 Author Posted May 10, 2021 Ok, I ordered brand new CO2 mag to try it out. I will post a short video later so we can basically see where the issue might be. I should get it on Thursday so awaits a video on that day.
