I don't know - I'm not buying that's even a gun at all, just yet. Things look funny on camera sometimes, but this is all wrong in a number of ways.
1. You can see the first two knuckles of the hand (which seems to be folded into a fist, or at least have the fingers curled) - which means that if there was a gun in that hand, you should be able to also see some of the slide, and the "barrel" ought to be way farther to the left than it is in the picture.
2. It looks awkward as hell for a two-handed grip - I just tried, and I'm not physically able to reach the palm of my left hand with my right, when standing in that position, with the left elbow extended.
3. The thing projecting below the hand is clearly bent, which makes me think it's more likely to be a loop of fabric or a strap of some sort.
4. That's a lot of empty space between the inside of the elbow, the body, and what looks like it ought to be hip/upper leg area (or a shirt or something wrapped around the hips). If I had to guess, I'd say it was a woman.
