Here is a slightly different view of the movie luger. Part 1 appears to be coming out of the frame and looks like a hook. Part 2 is sticking out beneath the barrel and part 1 it hooked into it. Sorry I don't have a clearer image. Maybe I'll have to get it on DVD and see if it is better...

Johnny, I'm beginning to think that what you describe above, is an optical illusion. With the barreled receiver out of battery, your #2 "attachment to barrel" would be even longer when in battery and therefore push against part #1. What I see, is the front flat of the frame, where the serial number is stamped, as item #2 and item #1 as a metal object reflecting light behind it on the same plane as the 2 white dots to its right.

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...
