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).

Skew binary number system Skew binary number system The skew binary number system is a non-standard positional numeral system in which the "n"th digit contributes a value of formula_1 times the digit (digits are indexed from 0) instead of formula_2 times as they do in binary. Each digit has a value of 0, 1, or 2. Notice that a number can have many skew binary representations. For example, a decimal number 15 can be written as 1000, 201 and 122. Each number can be written uniquely in skew binary canonical form where there is only at most one instance of the digit 2, which
