Probably was one of the Bounty Hunter Trilogy books, The Mandalorian Armor/Slave Ship/Hard Merchandise. Been a long time since i've read those.
I've read quite a few of them. Despite the dorkiness of them some of them are very good, especially by Timothy Zahn & Michael Stackpole.
Have you checked out the short story anthologies? Tales of the Bounty Hunters, Tales from Mos Eisley Cantina or Tales from Jabba's Palace?
Fun little pieces with some minor tie-in to some of the other books, particularly the Bounty Hunter Wars.
