Doesn’t come with romeo1 pro shroud or top plate for slide - SIG SAUER XSeries 3.9in Slide Assemblies

I was disappointed to spend over $500 on a slide, red dot, and high-sights, only to miss out on the stamped metal shroud for the Romeo1 Pro. I looked on Sig and they MSRP for $56. That’s insane for a piece of stamped metal. I recently purchased a compact P320 from a dealer and it came with everything that this one is missing and only paid $900... for a full gun. Also, my slides was blemished down to bare metal in two places. Most likely Sig’s fault.
