I've added two of the three firearms from the above link to the Custom Knighthood Order equipment purchase menu with tweak 3f, but I haven't figured out how to add the pistol, as the option to choose from a list of pistols isn't present in the conversation menu. Does anyone know how to add a pistol dialogue option to the CKO equipment choices?
