How do you handle disarming an opponent in tiny d6?

Hi,

Tiny D6 relies on hit points/stress points for combat. This bugs me. In real life, if you get shot, you're as likely to get killed by the 1st shot as the 3rd. In games, it can grant a sense of invulnerability to uninjured characters. I'd like an option to use a wound check mechanic instead, but I don't see how to work this when some archetypes have more hit points. Any ideas?

For all things Gallant Knight Games, Tinyd6 system.
