If you look at both pictures you can see that the parts in question are moving with the gun. In the second picture, the one with the numbers, you will see two areas that are lighter than the surrounding area, just below the trigger guard. In the first picture, those two areas are still in the frame, but further down as the gun has moved and the two parts are still in their in front of the gun. I guess I'll have to make an animated GIF to show that they are on the gun...
