I have a standard XDS (not OSP) and will shortly be picking up a Hellcat OSP. Reason I am posting this here is 1. There does not seem to be a Hellcat forum here and 2. I believe SA would use the same footprint for OSP sights on the XDS as the Hellcat. I remember the Hellcat was originally supposed to fit the Shield RMSC prism and another one that I forget but now there are a lot of other sights that might work, like the Sig Romeo O, the Crimson Trace and I have read good things about the Holosun 507c but nobody seems to have them in stock. If anyone has tried a prismatic red dot on the XDS or Hellcat I would like to know your impression about fit/ dot definition in different light conditions, etc.
Thanks, Shortgun.
