Couple problems happening here

These particles are a yellow / brass color as the deterent coating gets burned off, and are very small spheres or flattened spheres. To the average shooter they do appear to be "brass" particles, but instead are simply unburnt pwder particles and are quite normal when firing ammo loaded with some types of ball powder. I see this all the time when firing my Sigs with Winchester ammo...

Excellent info. It's not that I don't believe you or don't want to take your word for it, but these brass looking shavings are also shiny like they are on the casings. There are also large bits/chunks/strips of this shiny brass colored material laying here and there around the different parts of the gun. Is this powdery residue you're speaking of shiny as well? It shines when light is put to it.

Note how the left side of the cut is vertically aligned, and the right side of the cut has a step.

Does the barrel witness mark line up, and is the front sight perfectly vertical to the receiver and frame?

Now that you mentioned it, I see a lack of symmetry in the area you're talking about as well as a misaligned witness mark. Here's a photo.
