Since the Rogue Trader core rulebook nor any of the published errata have any rulings on how a weapon gains the Customised quality (Core Rulebook, Pg. 115), how have your games dealt with giving your weapons a custom job?

As hoped, they started seeking him out for additional work, no matter how suicidal - so far included Yu'Vath constructs and Slaugth. Close encounters with the Rak'Gol will be up next...
