I am still in the time out box for my UD-M42 and I am thinking about converting a Suomi Drum to fire with the UD-M42. I have zero experience in this area, but know the UD-M42 has the same magazine slot that the Thompson has. Since UD-M42 mags work in a thompson, and the M1 Thompson works with a "T" bar welded onto a Drum,
Then a similar set up for the UD-M42 should work.
Has anyone done this before? If so please post photos and measurements if you can. I have seen suomi drums adapted to Smith And Wesson 76s so this should be in the art of the possible.
Thanks in advance
