Her symbol looked robotic to me, like or robot leg or a piston.

I wouldn't be surprised if she had internal weaponry, but we until episode 8 we never saw nora carrying her rather large grenade launger, so she maybe be meant to have an external weapon but I'm betting it would look highly robotic or ave he same glowing circuit-like symbols Penny has on her clothes.
