I bought a Glock 17 slide off of eBay and these were the sights that were installed. Looks as if these are the Ameriglo Protector sights (https://ameriglo.com/collections/glock/protector). I no longer need them since I changed to the Trijicon HD. I do not know how old they are, but they still glow. On the side of the front sight it says AmeriGlo H3 17.
Please PM me with an questions. Asking $40.
