TM G34 Upgrades?
 

Hey, people.

I was recently having an issue at a game with my Tokyo Marui G34 not feeding properly. I was using WE mags, and every few shots I would get a burst of gas but no BB. I took the gun apart and everything looks fine, the slide cycles perfectly. A friend suggested that WE mag valves are too stiff for the TM, and as a result the valves would let off enough gas to cycle the slide, but not enough to feed a BB properly.

Said friend suggested that I just needed to change the hammer spring to something a bit stronger, and everything would be fine. Doesn't seem too difficult. Should I change the valve knocker, hammer, or hammer sear as well?

Please let me know what you think would get my G34 working at full tilt again.

Thanks!

Yes, if you want to reliable use the gun in warmer weather, or reliable use WE mags at all, replace the hammer spring with a 150% one.

We mag gas routes are also a different shape than the TM ones. WE will work in a TM without changing them but the TM routes provide a better seal.
