I posted several photos and stated that these sights were Spartan Operator Sights.
I was contacted by an anonymous, but in the know, party and told that I had made a mistake and I wanted to correct it publicly. These are not Spartan Operator Sights.
They are Ameriglo's submission to the FBI contract which the Glock 17M was chosen to be their new duty gun. You can check the Gov solicitation (pdf link at bottom of link) page 13, C4.14 shows the requirements for sights.
The clear distinction between these sights and the Spartan Operator Sights is the U-notch of the rear sight as well as the size of the front sight.
I think I'll be running these on my EDC Glock 19 soon.
