Most Helpful Girl
It completely depends on her personality and past. If she's a drama queen, has a bad past with guys, if she seems crazy, etc... then I'd be worried.
However, just because someone says the like guns, it's not a red flag. Maybe she grew up appreciating target shooting? Maybe she collects them? Maybe she likes to hunt? Maybe she's just trying to sound like a "guys girl"?
A normal person who likes guns, isn't going to kill you for cheating. A crazy girl might kill you for cheating... even if she doesn't have a gun. She might just stab you to death.
The real red flag is the girl's character; drama queen/crazy/not mature/daddy issues/very materialistic, etc...2THIS IS NOT RELEVANT ANYMORE
