Hey guys I am relatively new to the forums and I have just run into a problem with my MP9.  So what happens is everytime I cock the bolt back and load a mag, the gun will simply not fire. I can get it to work for short bursts but after those bursts I try and pull the trigger again and it does not work at all. I fill my mags for a good 15 seconds with brand new green gas. I am fairly confident that it is not the disconnector because when i cock it back without the mag in it can click, although i have to pull the bolt back as far as possible and let it go as hard as I can let it.

Please help! :(

Most likely your bolt is not returning all the way forward. You'll need to get your hands on a newer recoil spring.

Or just stretch the spring.   I had the same issue and it was a 10 second fix.
