1. Handguns lack the appropriate lifting properties to make them successful wings.
2. Given that you modeled the guns after the standard M1911, how are you expected to reload those guns after the magazine is emptied, since the base of the handle is attached to her upper back?*
I suppose you could just pull the slide back and expose the ejector port to try to jimmy a fresh bullet into the exposed chamber. Unless, the part attached to her back is the mag sleeve and the guns are not actually a part of her?
