Ok heres what happend. I bought two used Marui shotties (spas and m3 shorty). Both were shooting fine at first, but after their first field test both had the same type of problem. the pumpgrip would just slide down instead of cocking the spring. there was no resistance. besides that u could not pull the pumpgrip all the way back up to its original position.
after removing the shell and shaking the gun quite a bit, bullets would fall out and the gun would work again...

so far so good, yesterday both guns jammed right from the start, showing the exact same problem as stated above and now I couldnt get them to work again.

I have a really bad feeling about this, but maybe not all hope is gone. Is there anyone who had the same problem?
I can go and take pictures or try to explain more precisely whats happening if u can tell me what i need to look for.

PLZ HELP!
