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 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 case of left action. Monoids, groups, rings, and algebras can be viewed as categories with a single object. The construction of the opposite category generalizes the opposite group, opposite ring, etc. Let formula_1 be a group under the operation formula_2. The opposite group of formula_1, denoted formula_4, has the same underlying set as formula_1, and its group operation formula_6 is defined by formula_7. If formula_1 is abelian, then
