Welcome to the forum! try TM uzi hi cap mag internals in the MP40 mags, they fit very easy, even the base plate fits, you just need to add a piece of tube inside for the bbs to feed through as the mp40 mag casing is longer, I doubt thompson hi caps will work,

A tommy mag will work, you have to cut out 1 or 2 mm from the flanks, add a tube for BB and fit it in the mag.
Very interesting, any chance of putting up a pic of the mag in pieces, in the weapon section. ![]()
