I haven't watched Japanimation in quite some time, but this thread has reminded me of a particularly good mini-series: Gunsmith Cats. There are only three episodes (not counting the comics) but the plot is quite good.
Synopsis: The corrupt Chicago ATF division chief works with the champagine-socialist mayoral candidate to import black-market milsurp Russian firearms and ammo via Lake Michigan, and then enact a gun ban in order to raise the prices for their products on the streets.
The heroines are a gunsmith (who carries a CZ-75) and an explosives expert who work with a sleazy Elliott Ness wannabe cop to kill the Russian arms/drugs dealer and expose the whole works.
Another more proper series is 'Cowboy Bebop': After the Earth is destroyed, and other planets/moons/asteroids are colonized, the police are stretched far too thin over the solar system to keep the peace on every planet so they give out huge bounties to spur on private law enforcement. The main characters are bounty hunters who are well versed in handgun combat and martial arts and they scour the galaxy looking for bounty heads (drug dealers, terrorists, smugglers, pirates, mafia-types). Pretty fun and pretty funny up until the last episode.
