Hello ASC Gun doctors, I have a KJW M9 Beretta problem. This is a Gas Blow Back, that is run by propane. So I'll try and describe it with words.

So basically when a loaded gun is present and I pull the trigger, the gun will not shoot. But if I repeat the firing process such as pulling the trigger, sometimes I will hear nicks of gas, on rare occassions it will even do a full cycle or enough to blow the slide back but not lock in place.

The gun is greased and oil in the correct spots, the magazine shoots fine in other M9's. The gun does have some slight wear and tear, and the trigger spring is broken. But nothing that should harm the firing mechanism.

I've attached a video for reference.

YouTube- KJW Beretta M9 Valve Problems.

So above is the breakdown of the m9, Part 38 does not connect with the m9 magazine. When I remove the slide and look inside where their is a gap between the mag well and magazine, you can see the valve knocker(Part 38) And the pin on the magazine, and it looks like the magazine isn't long enough. But these magazines used to work flawlessly. I've counted every part and double checked the look, everything looks A okay.
