I guess in a world with all sorts of enhanced people running around, even subcompact pistol made to be as small and concealable as possible, needs magnum level firepower.
IRL, this weapon suffers from heavy trigger pull and of course, excessive recoil due to the .357 Magnum cartridge, but I guess thats not really a problem for enhanced coordinators. Using .357 Magnum also has the benefit of being able to load a weaker and lighter .38 Special rounds.
