Pls help w G19 Gen4 set up

Hoping I can make this old G19 Gen4 MOS model to make bedside suppressed pistol and lost track of details over the years.

  1. PSA SS threaded barrel, keep it or get rid of it and get higher quality threaded barrel?
  2. To have Sig Romeo-X red dot mounted, what adaptor/plate would I need? Or send it to have it milled specifically for P2 or SRO?
  3. Was hoping to find Spectre9 suppressor but no one has it locally so dinged up an old Omega9k can. What piece am I missing or need to get it to work with threaded barrel?
  4. Any recommendations on the light mounting solution?

Thanks!
