Actually between 1937 and through the end of WW2, the central approval committee for Red Army small arms conducted a number of tests, including a bodyweight test. Throughout WW2, Lev Andropov, a 205 kilo (450 pound) man who was a disabled veteran of the First World War would sit on all designs while eating his lunch. If the weapon did not break, it was approved for that stage of testing.
