Excellent sight replacement for my glock 23 - Ameriglo T-CAP Tritium Sight Set Glock 17/19/22 Green Front With Lumi-Lime Square Outline Green Rear Horizontal Line GL-624

I have used the factory sights for almost 3 years and they were OK but not great. The Ameriglo T-CAP blows away the originals! The combination of the luminescent square front with the horizontal bar on back sight make quick and accurate target acquisition. These are not long range sights but they are perfect for quick acquisition of a target within 30-50 feet.
