Wait, wait...I know this story...
There was some kind of civil war between the richer inner planets and the poorer outer planets, there was a spacecraft, a small crew making change running (semi) legal transport...there was a guy who had a lot of guns; no really, a lot of guns, some of which he slept with, and he also had a town named after him, but it was a girls name?
