Slide not locking forwards when loaded

[Adam3088]

Having some issues with my g19, when an empty mag is put in, everything does what it should. But when the mag has bb's in it the slide will only move 3/4 of the way forward and stop, looking inside it seems that the bb is only being moved about half way between mag and hop, just sort of falls off the side of the little ramp bit, which jams it.

 

Anyone got any ideas? Can post pics if it helps.

Worked it out, lump gone from the loading/gas nozzle. Just need to find somewhere in the UK which sells them now!

Firesupport should have what you need.

Unless I'm being a dumbass it's not there. Any idea if other brands other then kwa are compatible with KSC glocks?

Not too sure tbh, you could try Elite Shooting Center, they do a lot with pistol bits, upgrades, replacement parts etc iirc?

They don't do glocks.

Unless other manufacturers are compatible it seems like you cant get them from the UK, balls.

 

Only one I can find is from 'airsoftglobal' http://www.airsoftglobal.com/shop/index.php?main_page=product_info&cPath=634_1053&products_id=18822

 

Never heard of them before..

Firesupport show 3 KWA Glock ones in stock, thought they were similar internally but could be mistaken.

Can you link please? KWA and KSC are essentially the same thing.

 

Tried searching but cant find them!

 

 

Edit: Cancel that, found them

 

They just call them 'nozzle' I was trying every variety of gas/loading nozzle but not just the one word.

[straffham]

Yes its same part no as your link (22):

Can't link direct from my phone sorry!

[straffham]

Ah, you've got it lol!

[Adam3088]

Ah, you've got it lol!

 

Thanks anyway!

So the new loading nozzle fixed the first issue, now I've got another one.

 

One of my magazines just doesn't seem to fire very well, either doesn't cycle fully or after a few shots vents all the gas.

 

Could this be the valve is getting stuck? Is there a way to fix this without buying a new valve?

[jcheeseright]

Empty the magazine of all gas, put a couple of drops of lightweight silicone oil into the knocker valve and then push it in and out a shitload of times til it feels smooth. If that doesn't work, you could try taking the valve out and giving it a good clean.

[Adam3088]

Better! Fired much more consistently, it did still vent after a while though. Mag was extremely cold afterwards but I presume this is just a side effect.

 

Another problem that I seem to get is that it misses shots, mag is loaded correctly without gaps but every few shots it will stop loading bb's into the hop up even though it keeps firing. Cocking the slide back again forces the next shot into the chamber so I'm not sure why it's not doing this as part of the cycle!

[jcheeseright]

is it still doing it after the valve was cleaned? that normally happens as a result of 'light striking' when the valve isn't depressed enough to let enough gas out to cycle the pistol fully.

[Adam3088]

Gave it a spray of oil and kept pressing the knocker valve, doesn't feel stiff at all.

 

Could it be the striker is worn as well? Although I suppose that wouldn't cause it to vent.

[jcheeseright]

could do, if it's releasing so little gas in the initial hit that the slide doesn't reset the hammer it'll just keep venting til it's empty.

[Adam3088]

Well, that issue seems to have gone away now! Perhaps the silicon oil has worked it's way in a bit more over the last couple of days as I just emptied both magazines and other then the slide failing to lock back on one (meh) both fired fine.

 

Only other problem I'm having now is the gas-in valves are leaking, any idea what size o-ring is needed for these? Tried the oil trick without luck, seems like new rings is the only way.

[Airsoft-Ed]

Are you sure it's the valve that's the issue and not just the base plate O ring?

Try dunking it under water to see where the leak's coming from.

[straffham]

Is it the same make mag as your others? If not it could be tolerences are out which is causing the misfeeds (and maybe the damage to the loading nozzle)?
