Now yes while your example is 100% correct for a normal human who would have to plan, take steps and collect the materials to perform said action and it wouldn't be in their hands but the person in question were talking about is someone who can generate, control and direct electrical current and energy in general.

The parallel currents on both sides of her arm run up and end at her finger tips creating a muzzle for the gun and as long as the coin itself is metal say a token its entirely possible. And because this person can do this it stands to reason this person would also be resistant to the kick back adding in the fact that she was braced against the flooring. If you control fire would you still get burned?
