m226/p226 wont cycle properly

[majorairsofter]

hi so my kwa m226 ptp has a problem.

When i gas my mag and fill it up with bbs then pop it into the gun and then rack the slide. The gun will fire at a slightly lower velocity then regular so the next shot makes a odd noise. The slide will move less than a cm that happens for mutiple shots i have to use the double action, and keep shooting many times until i get weak shots. That actualy blow back the slide enough to put a bb in the chamber and to get the hammer back this happens a few times until i am about 3/5 th out of gas. Then the next 2/5 th of gas is the really strong nice blowback, and then i run out of gas or bbs like 10 good shots or so.

so any help would be appreciate i can post a video up if you guys need it

I would tend to think that's the symptoms of a weak hammer spring or screwed up valve striker (can't do it at higher pressure but when the pressure drops it's fine).

That is not the first I have heard of the KSC/KWA P226 issues. Weak/worn hammer spring try getting a new one or seek a testing transplant from a functioning GBB.

Still thinking it is a hammer spring issue.

You've checked that you haven't got a cracked nozzle right? (not the tip of the nozzle...more the top side of the body)

Some are obvious...they looks cracked in half. Some are hard to spot unless you take it out and flex it.

okay well i have no idea how to access the hammer spring other wise i can change that and its not the loading nozzle i checked

I think you may be right with the striker valve idea it seems to work when there is less propane = less pressure right. Where can i find a replacement?

This happened because I barely filled it up and it worked right away, but then when i filled it up full it did not work like in the video.
