Great sight - AmeriGlo Glock Classic Style Tritium Rear Sights

I purchased the Ameriglo Agent set for my Gen 3 Glock-19. They are fantastic sights! You can acquire the front sight ridiculously fast with the U-notch rear. But out past 25 yards, I found that my accuracy suffered. (I’m 59 so your mileage may vary). My Glock 23 has the square notch rear and I am far more accurate with that set. (Ameriglo Bold). So I opted to change my Agent rear sight to the more traditional square notch. Ameriglo confirmed that this was the proper sight for the .180x.140 front. This 875r is perfect and as an added bonus, it is shorter (front to back) so it is no protrusion out of my IWB holster. I couldn’t be happier with Ameriglo and their products.
