It uses a rotary action that allows for maximum concealment.
Forgotten Weapons checks out the French Rotary Action MGD PM9 Submachine Gun.
Ever hear of a rotary action? Well this French submachine gun has an action unlike any other. The rotary mainspring is like a clock spring. It allows the weapon to be much smaller. The whole package folds up into a small size originally invented for French Police to be concealable.
This small sized 9mm submachine gun actually uses left over 32 round capacity German MP 38/40 magazines from World War Two. Now that is wise to use all of those surplus magazines available at that time in post war France.
