I am digging those sights, who makes them.
I don't know. I like them too. there is a generous notch in the rear and the front sight is slightly thinner than a stock Glock, plus quick to acquire and easy to see with the fiber optic
The contouring and stippling I like too but I have not shot it to really get a feel for it.
Maybe on Taran Tacticle's web sight they spec out the sight they install.
