You left out the one detail I am looking for Ron. The toggle wouldn't even open the way this Luger is moving...
The problem is that the toggle is opening without the toggle knobs striking the frame ramps or EARS... Unless this happens the toggle should remain locked closed upon firing... If this were not so... our dear friend and mastercraftsman THOR would probably have lost a finger when he attempted the firing pin drop on a live cartridge in only the upper assembly...
The mere thought of that test makes me nervous...
DON'T TRY THIS AT HOME KIDS!
This Luger is really emulating the loading process rather than shooting... and the simulation of firing was probably an afterthought by the graphic artist...
