My m9 broke (AGAIN!!!)

[Patrick750]

So I pretty much gotta lemon from KWA. I'm no going to fix it AGAIN but I do want to know what's wrong with it. so this is what's happening
-pull trigger, slide goes back, nothing happens, bb's pile up in chamber and spill out %40
-pull trigger, slide goes back, bb's stay in but hammer goes back and forth so fast it's a blur%40
-works fine %20

I JUST got new mags for it. I treat my pistol quite well and always make sure i have lubed gas. What's wrong with it? It seems that the faster i shoot it the more problems emerge but if i shoot only a few shots slowly then it works fine. The one good thing out of this is that I now have room for a new KWA mk11

Try turning down the hop-up. Mine started jamming when I had it all the way up (to use .40 bbs for no good reason). Anyway, its worth a shot.

Okay so I had it all the way up for some reason and it turned it down and it was more consistent. Thanks, but I still don't trust it.
