Default MAC-10 SWG Jamming Help

Hopefully someone has some advice.
I have a SWD/Cobray MAC-10 A1A Full Auto I bought new.
In great shape using new Zytel 32rd Mags and new 115gr 9MM ammo from
Federal or other bulk manufacturer. After full cleaning, still cannot go more
than 8-10 rounds before jamming. The spend case will not extract fully
before the bolt returns forward and jams.
Any ideas ?
Is the ammo too weak to reliably cycle the rounds ?
Are the bolt springs too strong ?
While not the most advanced SMG, I should be able to get more than a few
rounds through it.
Any help / advice is most appreciated.

Bought it new? Full auto?

Welcome to FTF. How about you go on over to the Introductions thread and tell us a little about yourself. It's good to see another PDX'er here.
