MAB PA-15 pistol MAB PA-15 pistol The MAB PA-15 ("Pistolet Automatique 15", also known as the "P-15" or "P.15 Standard") was designed by the Manufacture d'armes de Bayonne. The model number, 15, refers to the magazine capacity. When introduced, this was the first pistol holding a greater number of rounds than the 13-round Browning Hi-Power. The PA-15 was introduced in 1966 along with a short-lived 8-round version with a single stack magazine, the P-8. The PA-15 was designed for commercial sale, primarily for export as French laws severely restricted the possession of "military-caliber" arms (which included the ubiquitous 9mm). The pistols were proofed
Opposite group it is equal to its opposite group. Also, every group formula_1 (not necessarily abelian) is naturally isomorphic to its opposite group: An isomorphism formula_10 is given by formula_11. More generally, any antiautomorphism formula_12 gives rise to a corresponding isomorphism formula_13 via formula_14, since Let formula_16 be an object in some category, and formula_17 be a right action. Then formula_18 is a left action defined by formula_19, or formula_20. Opposite group In group theory, a branch of mathematics, an opposite group is a way to construct a group from another group that allows one to define right action as a special
