It depends. For example, if he picked up his father's gunblade:





he wouldn't have had time to test it since the incident in the throne room and it is different from the one Zenos used previously. And then there is Fandaniel's dialog which indicates it is a weapon he doubted Zenos would have selected and he knows Zenos dumped the gunblade in favor of a katana.

And the Final Fantasy series does like giving it's main villains longswords with red blades; Ardyn Izunia being the most recent example.
