Pistol Trouble

bullets

Just got my First GBB's today.
KJW M9 and KJW P226.
What a difference betweens two pistols from
the same manufacture. The M9 is crap
compared to the P226 but it does provide
a tiny tiny bit of a kick.

So Got my 134a Abby green gas.
The P226 fire flawlessly.
The M9 has pissed me off!
The Mags look the same but are incompatible.

The M9 I load the mag with Gas, load the BB's ensure
they are stacked right. It Fires fine for about 6 rounds,
then fires every 2nd pull of the trigger for a BB or two then
finally completes the action, recocks itself and just fires nothing.
When it get lower on Gas but still enough to work the action
the nozzle/plastic pistol start jamming.

Worse still when the Mag is empty most of the time the slide
does not hold back and the M9 will happily fire away and keep cycling.

The Magazine feels a bit loose when fully home. When it stops fireing
the BB's if I take the mag out and replace it it fires one then stops.

I sprayed Silicone Oil EVERYWHERE. the Seals the rubber bits, springs,
may, nozzles, the Barrel. Did not have any effect.

Where did you buy them from? I don't think I've ever heard anyone have trouble with the KJW m9 before.

Sure you didn't accidentally get sent the Bell?

Got it from eirsoft,
Yep tis the KJ one, I got pics posted on the photo thread.

Dont know enough about pistols to determine if its the mag
or the body of pistol thats causing the problem.

The P226 fires like a dream but theres no kick at all off it.
Got that from Airsoft Direct. The M9 has a lovely wee kick off of it!
when it does fire.

Bullets, if you send it back to me, I'll either attempt to fix it, or give you a refund - whichever you prefer.

Cheers, If I cant figure out whats up with it I may send it up
to ya as a last resort to see if you can spot anything.

Hopefully a few people here may chime in with a few suggestions
or get me to try different things.

I could also try and aquire another mag just to see if
its the mag or something else. I will examine it more carefully
in the morning when I have good natual light.

I would have gladly paid that price for a replica that did feck all
so I am not worried about money etc but it would be nice to get the
thing working.

Have this gun. Try putting upward pressure on the mag while firing.

This helps a little bit. Fires out about 10 but after that every 2nd trigger
pull results in nothing being fired.

If I fire VERY slowly I get less "empty fires" if I can use that phrase.
As soon as I double tap or its the end of it.

Once thing to note too is the the P226 appears to fire the BB's a lot
faster. The M9 fires slower.

When Filling the mags, I fill them for about 5 seconds,
then go back and try fill for another 2-3 seconds.

sorry to hear about the bother you're having bullets, I received my m1911 the other day from Tony as yet I haven't managed to test fire as I haven't been to b+q yet for propane as yet..

The gun is only semi cycling. Clean the piston, can you do that?

Sorry for my ignorence in the ways of airsoft guys.
I have everthing that I can dis-assemble without tools
and taking out screws etc clean and lubed with silicone spray.

Correct me if I am wrong. I am assuming the piston is the plastic
nozzle with the plastic edge that strips the BB from the Mag and
shoves it to the front of the chamber ??? Thats clean and oiled.
The plastic piece that does strip the BB touches the rubber piece at the
top of the mag where the gas exits dunno if this is normal or not.

If ye guys got a check list of all the things I should go through
let me know. I dont know how to fully take it down yet and am
not sure I want to yet. Will do some googling tomorrow.

The piston(what i call the piston) is in where the gas transfers from the mag to the slide. If dirt or liquid gets in there it can cause problems. There is a plate on the base of the slide. Unscrew it and the piston will fall out in your hand(WARNING! COMPRESSED SPRINGS,MAY FLY ACCROSS THE ROOM!).

BTW, how many mags do you have. Try somebody elses and see if there is a difference.

Only have the mag that came with it. I tried unscrewing the screw on the plate where the nozzle/piston is. just behind the rectangular opening where the gas enters the slide but could not get the plate off without risking damage to it. It would not come off.

Upon examination I noticed the odd time when moving this back and fourth that it locked. I have a pic of it locked below. There was a plastic
nozzle and behing a bit of rubber that it rubbed off of and compressed.
Dont know why it did this but Massive amounts of spraying later caused it to lock less. Also the mag does not sit 100% flush with where
the BB gets pushed from the chamber to the Barrel. The mag is a litttle loose.
I may try some PVC tape on the sides of the mag to remedy this.

Anyway I tried firing a while ago and it managed to fire 40 or so BB;s
without a misfire. Hopefully its Just that and problem solved.
Will do a bit more fireing later on to test it out.

Thanks for the help all. I hope that fixed things if not ya will probably
here me moaning and whining in frustration later or in a few days.

I'm guessing this should not stick out against spring pressure every so often
and that sometimes its catching on something and staying out:

iceage

just wondering is it a bit of a gas issue as well.. these babys are all metal and have metal slides and so on. Have you used propane yet? From what I've read up on it tends to have a bit more punch in it to cycle metal slides and so on.;)

The Green gas I am using is just propane mixed with silicone oil.
But I am going to try pure propane tonight while giving the mag etc
a spray of silicone oil. Will let you know how I get on!

[EDIT] Whoooooo iceage ya may be onto somthing
Pure Propane with Silcone oil Feels WAY better
and just empty's a mag without any issues!!!
(and it fires now at the same speed as my P226
which is weird as the P226 has a heavier slide)

But.....it only lasts for a full mag
when I insert new bbs the gas runs out
after 2-3

This happened to me. 1. The back of that chamber is a rubber disc which is on a knob(Be mature) at the back. If this comes off it will misfunction and jam it foward.
2.If there is stuff in there when you fire it freezes, jamming the pisont foward.

The piston is on a spring so it allows the bb up and then pushes foward. If it jams or moves to slow, you get the above symtoms.

To get that playe off you have to pop it off with a small flat screwdriver as there is a catcha at the back. This may not be necessary. Take a strip of j'cloth about 1cm wide. Push the piston foward a,d push the strip in. Remove it, and repeat until it comes out clean. When this is done put the smallest squirt of silicone in. Now manually push it back and forth to spread it. Hopefully will work.

Cheers, Did not need to take the plate off in the end.
I tried with a flat headed screw driver but stopped as nothing
seemed to be coming off and I did not want to force it.

With the Propane only (smell less pleasant) its fireing way better.
So it may have been a combination of those two things.

glad to hear that helped:D it kinda answered a quetion of my own, prpane seems to be all the rage at the min, and seems to be ideal for all metal models, although i've heard from other sources it can damage you piece:eek:

I wonder could shiva maybe give us some clues as to whether theres any truth to that? i.e blowing seals an stuff! or is it the silicone that is the solution to these horror stories..by the way I don't have liquid silicone, only a can of pingo silicone-spray will that do as a general lubricant and will a dash of it into the top of a propane bottle(when I get one):)

I got my liquid silicone from Airsoft innovations the same place
the makes the propane adapter. I have not used it yet.
A friend got me the Lidl spray and I got another silicone spray from Airsoft
direct which seem to be working well.

Propane will damage your gun if its not strong enough to take green gas (HFC 22). It might not blow up spectacularly the first time you use it, but if the seals, nozzles and slides aren't designed to withstand the higher pressure, eventually they'll just give up and fail.

Most guns nowadays can take both HFC22 and HFC 134 ( the regular, non-green, blow back gas). It is usually recommended that the weaker HFC134 is used with Japanese manufactured guns (Tokyo Marui for example) and the stronger HF22 be used with Taiwanese models, for reasons of pellet velocity limitations (Japan has a lower velocity limit than Ireland - .8 Joule I think. Thats why Classic Army and ICS guns are usually slightly nearer the 1 j mark) and because Taiwanese models are now often equipped with metal slides rather than plastic (which is universal for Japanese guns, because of Japanese replica laws - again, the reason CA and ICS are usually full metal), meaning that they can take the higher pressure and may not even cycle with lower-pressured gases.

Now that you've read this far, if you use propane to power your green gas powered gun, and it explodes, killing all life for a radius of 5 miles, I'm not responsible...the above information is just what I've read. I may be completely wrong, so use it at your own risk.

iceage

no worries Shiva, like any instructions that come with volatile substances i.e. fire, explosion, or generally a bad day!! we all agree that we use at our own risk!:)

o1s1n

Airsoft guns can not shoot above something like .98 of a joule in Japan. So it's more or less the same as here.

The reason they have to use lower powered gas is due to there being issues with replicas made out of steel in Japan. Therefore Marui stick to plastics. Plastics don't like high powered gas.
