KJW Sig Sauer P226 not accepting gas

[MySwan]

My friend's P226 by KJW was dropped from a pistol lanyard about 4 feet high and slightly bumped a carpet floor barrel first. Now whenever he puts any of his mags in the gun it will not fire. I need to know what's wrong so I don't need to buy him a new gun or new slide.

have you tried opening it up and looking inside?

[MySwan]

Yes I have and I have compared with my GBB (Tokyo Maurui Tactical Master M9) and his brothers Timberwolf. I can't seem to find anything out of place between them but when a mag is gassed and loaded the P226 just won't shoot. @Rentax

The valve knocker spring might be broken.

If you can, take some high quality, well lit pictures of the replica (inside the slide, the frame, all other components that are easily visible), that'll help enormously with trouble shooting.

Everything looks fine there. The issue might be in the parts between the slide and frame.

A picture like this, only focused better would also help.


Can you take the slide off, remove the mag and dry fire the gun? Check to see if the hammer is moving (silver part sticking out into the magwell, on the back of the grip). If that's moving, then check the valve knocker.
Make sure the mag is gassed up and then press on the knocker button. If it's working correctly, it'll vent gas out the top. Being hard to press is normal, but you should be able to do it with your hands, no tools needed.
If the knocker isn't venting, then it could be a sign of the mag being over gassed, which is causing the gun to not function, or the knocker is broken.

There's also a chance the mag catch is busted and causing the mag to not seat correctly. I couldn't really see a catch in the picture you posted, so that's another thing to check.

Retractable lanyard, this wouldn't have happened.

Short of looking at it in person, I'm out of ideas. Sorry

While the pistol is disassembled, look down the Mag well, pull the trigger, does a small square metal object push out from the back wall and then reset? The item in question is the hammer that hits the gas valve on the mag. Often times these break, you should check to make sure that is working and in tact.
