My most obvious anti-gun is like a ninja magneto. She can alter bullet flight paths where even someone who shoots 100% accurate would miss and there's nothing they could do about it besides hope she's not focusing on their bullets. with her reaction times able to keep up with bullets as easily as softballs, you're in major doo doo if that's all you rely on. Then if she gets close enough she could fling people around who has any metal on them, such as armor, or shoot objects like a railgun. She can magnetize anything, but would need to touch it.
