I still think that by the 51st century any decent style-loving noble will want a gauss pistol, or an autopistol/advanced combat pistol for style. Revolvers would be seen as passe' by then.:devil:
Yeah, maybe...but in a universe that seems to emphasize a lot of tradition with regards to swords and the skill to use them I don't think the revolver is a stretch when worn as part of some formal get up. For everyday use a more practical combat pistol is more reasonable but for going out to a black tie affair, court appearances, or ceremonial duties a revolver might be suitable.
Besides, a noble might reasonably be accompanied by a retainer or two, which would be armed to the teeth if the situation required it, so the weapons carried by the noble would be superfluous.
