The MGD PM-9 was a French open bolt submachine gun, designed in the late 1940s or early 1950s by Louis Debuit and manufactured in small numbers by French firm Merlin and Gerin in the 1950s.^[1] The PM9 was an unusual design in three different ways: it employed off-axis delayed blowback, it had a clock-style spiral mainspring similar to that of the Lewis gun, rather than the cylindrically-coiled spring used in the vast majority of self-loading firearms and, most unconventionally of all, used a rotating flywheel as a delaying mass in conjunction with the bolt.^[2] It was furnished with a folding magazine, and some also had folding buttstocks, and this together with its original operating mechanism results in a highly compact weapon, but there is no known record of it being purchased or deployed by any military or police force.^[2]
