Now, keep in mind, depending on the situation, a PC may be able to keep opposing the opponent's skill check to remove the Aspect (kicking the gun away, for instance). *And* the PC may be able to follow up that Disarm maneuver with a Social Attack to get the opponent to surrender, and with a Fate Point, tag that Disarmed Aspect for a bonus. Heck, with a Fate Point, they may be able to trigger a Compel.
But this doesn't change the answer which folks have already given.
