Ha!
Nah, the AT-4 is still backwards. You can tell because the yellow band is near the muzzle. The .45 is still going to take the guy's thumb. I wouldn't put my thumb behind the slide of a 9mm, let alone a .45.
He is clearly not about to fire. He is posing, maybe pulling back the hammer (assuming that model has an external hammer?). Thumbs can move, so I've heard, so maybe he would move his thumb before aiming. Also, I can't believe I'm involving myself in this discussion...
