Alright, I filled in as much as I could, but the gun in the small of her back and the double-action-only on her left hip are still pretty ambiguous to me. I have no idea why anyone would go through the trouble of tricking out the M1911 with that much crap, though... -_-
Looks like a USP compact under her left arm due to the sights and the grip, but the internal hammer looks like its off a glock. I guess its conceivable that you could have a custom made USP compact with an internal hammer, given that its so small anyways.
The shotgun on her back is NOT a model 97, as its a side by side double barrel. Its probably a model 1900 remington due to the shape of the stock and the lack of engraving.
The gun on the small of her back is possibly another revolver given how the grip protrudes so far from the hammer.
