Breech block not closing

Olle · 05-09-2012, 12:07 PM

Got a problem that I hope is easily fixed: My "mixmaster" Luger won't go into battery when I load it or shoot it. It ejects, cycles and feeds fine (using UMC 115 grain) and the barrel extension goes all the way back, but the breech block stops about 1/8" open. Once i push the toggle down, it will shoot just fine but will do the same thing again. It seems like it just doesn't have enough "oomph" to go all the way.

This last fraction of an inch seems to be a weak spot in the design, the final closing appears to be more a matter of inertia than spring force so I'm thinking that it's dragging somewhere. A bullet will drop into the chamber without any problems and it will close fine without being loaded, so I'm thinking that the problem could be either in the mag or the ammo. It's just losing momentum somehow. Any ideas?
