I need a new set of night sights on my g19 gen2. It has the factor night sights on it still from the factory. This will be my EDC so i'm looking for the best sight i can for defense. I also love to shoot this gun at the range, so i want to have a good range picture as well. Right now i'm looking at these. Trijicon HD's http://www.trijicon.com/na_en/products/product1.php?id=HDNS Ameriglo CAP's or some version of the CAP with either a pro operator rear or black rear. http://www.ameriglo.net/catalog/sights/pistol-sights/glock/night-sights/complete-sets/u-rap XS Big dot http://www.xssights.com/index.php?nID=sights&cID=Sights&pID=sights&sID=handgun This sight system has also caught my attention. Speed sights Tritium night sight. http://shop.speedsights.com/glock Any input from people who have used any of the sight mentioned would be really helpful. I have read a lot about the Trijicon,Ameriglo, and XS but not much is out there about the speed sights. Thanks for the input.
