I had other things to say. But the real thing is, the expertise that a person who really knows their stuff is impossible to imagine if you havent seen it.. I was thinking,if a thompson submachinegun had any of the troiubles my brand new Japanese Thompsons have, the'd go right to steve, nationally known, and he'd un screw them No American would attempt to fix a Thompson that had the problems these new guns from japan have.
I kind of think the new ones are a scam. Having inspected them, I suspect the low number is because they haven't any expertise necessary to unscrew the problems. SO you make 700, and 700 people are greatful to have them. And they are all kinds of messed up.....and I end up buying two.
The one that won't mount a magizine, I'll have steve look at it.
I spent a day with calipers trying to get good measurements of USGI mags and guns vs Japanese.
I think Steve can make a wedge and hit a mag with a hammer and do a conversion.
The issue remains Cerwyn is right you are loading a bomb, into a bomb.
