GPO, German Precision Optics has that type of scope, the Spectra 6x 1-6x24i.
I have no vested interest in GPO or dealers, just something I found.
Illuminated dot German number 4, 4" eye relief, lighter weight at 1.1 pounds. I am only quoting from their specs but it checks all the boxes for me. I prefer a 1" tube versus a 30mm, but current offerings don't exist. Trijicon, which my gunsmith recommends with the post, green triangle reticle is in only a 30mm tube.
I have no idea of the ruggedness of GPO in real world use on big bores. A good warranty, but that means nothing until I have put several hundred .40+ caliber loads downrange. I will research reviews.
@michael458 testing has revealed a LOT of valuable information on which scopes work (Nikon African or Slug hunter) and the rest of nice scopes that break.
Camera Land in NY has these on their website. I have never seen or handled one but am quite interested.
