We MEU 1911 problem
 

Hey there, so yeah. I just finished sanding and polishing my MEU, it now looks amazing but it wont shoot anymore, when I fill up a mag, cock it and shoot, the gas just escapes out the barrel slowly, sometimes it will half cock the hammer back but thats it, any idea what could be the problem?

thanks

how far did you disassemble it to polish it?

I disassembled it completely, only thing I didn't dissassemble was the piston/nozzle assembly

bump

I had a similar problem with a ksc g19. It had something to do with the knocker staying against the valve on the mag. Did you stretch or deform the spring that holds back ther knocker by any chance?

Get someone who knows what they're doing to put it back together correctly for you?

I bet the sanding dust is keeping the hammer pressed on the valve! Maybe..... I hope. Good luck Ronan!!

it could be just somthing small like a broken o ring
