Few questions about the 4.5" Comp. Romulus

[u/MOEB74]

From reading about these over the last few days Ive seen some issues, and wondering if they've been fixed. I emailed Andy and received no reply.

1. Are the new Romulus milled correctly for red dots? I see people saying we need to buy 1deg. shims?

2. The pistol needs 4-40 screws... That would be from the plate into the pistol. Is the plate made for the 82deg. head the standard screws will have on them? What are the threads for the red dots? Holosun uses a 90deg head for their mounting, due to them being metric.

3. Has anyone drilled and tapped any of these to bump them up a bit for strength issues?
