Hi all!

So, this is my first post... but.. I'll try to make it worth while.

Problem
I've noticed an issue with using green gas and/or propane in hot climates. When pulling the trigger, a puff of gas is released with the slide traversing a quarter of its full travel. This will continue until the magazine's gas & gas reservoir has cooled sufficiently.

Solution
I've replaced both the hammer spring and recoil spring to fully depress the magazine's gas release valve. This won't let additional gas flow through in colder environments, it will just allow the gun to function properly in every environment(hot or cold). After taking apart the M226 that was on display at Evike, I found that a compatible spring(s) would be the Tokyo Marui MEU .45 150% spring. It has a very similar outer and inner diameter on both the recoil and hammer spring. The main difference is the length of the spring. Here's a link to the spring: http://www.airsoftpo...oducts_id=31046

Enjoy!

I have a question, my m226 is very odd and weird because when i try to shoot it on my backyard it will work and not work sometimes... and most of the time when i take it to games and it's like 80 or more outside it wont work.. it will either not do anything or all i will get is a puff once i pull the triger...

so my question is, if i buy this recoil and hammer spring the problem might be fixed? i bought a 160 dollar gun hoping i could use it on the field :(

How old is your gun?  If it is within warranty I strongly suggest that you send it in for repair.

Did you ever clean and relube the gun when you got it new?

What gas are you using?

Ever use excessive amounts of silicone oil that could have gotten on the bucking?

Are you experiencing a jam?

Did it ever work or is this something that's been happening recently?

I am not happy in reviving this post from 7 months ago, but I hope to get some pity out of what I am asking, especially considering that this is the only thread that offers some kind of DIY fix..

Has anyone tried this solution? Has any fix been confirmed to remove the puffing?

Thanks in advance,

As promised, here is the complete video guide on how to upgrade the springs in the KWA or KSC p226 PTP

https://www.youtube....h?v=9-V1DpLw-2w

Remember: KWA and KSC products, while very similar, cannot be officially stated as identical. My guide should work perfectly on both versions of the P226. The pistol on my video is a KSC.

Also note that the major cause of puffing is caused by the overfill of the magazine. Since I learnt the correct way of loading gas in GBB mags, my P226 has never failed. Ever.

First off, I own a KSC and not a KWA so I must emphasise that, officially, this post is just some border line opinion from some who does not own the exact, precise, identical product you do.

This said, I believe that set should work appropriately. Remember that the stronger recoil spring might cause your gun not stay with the slide in the recessed position after firing the last BB. Also note that stronger springs for recoil might translate into less felt recoil because the slide encounters more resistance when being pushed back against its recessed position.

So if you want you can try and install the striker spring only and leave the recoil one original. You can experiment, of course.

Remember these are the opinions of a KSC owner which seems similar to a KWA but it is not, as the staff here has made very clear.

I would wait for all the KWA users here (so many of them, ready to help you) to chime on the matter and then use their opinions for a more weighted support.

My 2 cents,
