Model A has a manual safety on the left side of the frame as well as a Browning-style grip safety at the rear of the frame. This feature ensures that the firing mechanism does not operate unless the grip lock is depressed against the palm of the operator's hand, thereby eliminating chances of accidental firing of the weapon.
The slide is marked: Pistolet Automatique MAB Brevette Modele A. This translates from French as: Automatic Pistol MAB Patented Model A.
MAB Model B
The Model B appeared on the market in August 1932. It had even smaller dimensions than the preceding models and in appearance is similar to the Walther Modell 9.
The receiver has a similar shape as the Model A, but the barrel is fix mounted, and the slide is open at the top.
Production of the MAB B ended in 1949. There are no reports about numbers produced, but there were many.
