When you need a no-hassle, fail-proof Glock Night Sight, look no further than XS Sight Systems Defensive Express Standard Dot Tritium Sights. XS Tritium night sights are the easiest to use sights on the market for quick acquisition of the target. The XS sight systems are among the fastest and most accurate sights on the market for those of us who need to work in low-light situations.
Those who've tried the Big Dot Tritium night sights and found the Big Dot to be a little larger than they felt comfortable with will find this one just right. The standard-sized front dot is about half the size of the Big Dot, making the front sight roughly the same size as those of the competition's Glock Night Sights. Once you've tried XS sight systems, you're not likely to go back to any other sight.
Sight alignment in low-light is a simple matter of dotting an "i." Pull up, line up with your target, and put the dot on the target while it's on top of the line on the rear sight and you're on. No fussing with proper position and guessing if you're on or not. A bonus for those who conceal carry: The rear portion of these sights is fairly low profile and won't bite you when holstered at the waist like some other high-bladed sight systems.
XS sight system Tritium night sights won't let you down when installed as directed. There are no batteries to burn out, and its glow won't stop because it's produced by the Tritium isotope, not a phosphorescent paint or a fiber optic component. They're not too bright so that you won't have issues with their glow obscuring your view in some lighting situations.
