Looking for advice on disarm

So in my most recent session I had a combat with clockwork soldiers. I had the monster disarm a player they got a critical success, they then picked up the weapon and I had them stow it.

The players defeated the combat and got the weapon back but I was thinking on it and I wasn't certain there was any way for the player to get the weapon back without killing the enemy.

I personally didn't like this but I haven't been able to come up with a solution.

As such does anyone have any ideas on how to handle this situation?
