Hi David, actually, the drums are, on a large percentage, not even usable right out of the box! They don't fit but just a few Lugers, they fail almost immediately with jams in the mag and in the gun...and almost immediately break as well!!! As far as I know, every one from first to last is the same, although they did seem to improve their assembly procedure a little as they went, but, all are basically the same parts, springs, etc.... When we're done with them, you really can barely tell it from an original? Just a little lighter gauge steel, and maybe a little softer steel as well... It takes a ton of work to make them function correctly..... But, we're doing it, one by one.... I have mainsprings already made for 50 units!
... once I reach that point... then it decision time... as quantity material order is the only feasible choice for the future.... (big numbers for old GT!...
)... best to all, til....lat'r....GT.....
