XS Sights GL0011S5N DXT2 Big Dot Night Sights for Glock

The XS Sights GL0011S5N DXT2 Big Dot delivers fast target acquisition in low-light conditions with its distinctive orange outline front sight and white bar rear sight. This tritium night sight system transforms standard Glock pistols into reliable defensive tools that perform consistently from daylight through complete darkness.

What Makes This Different

The DXT2 Big Dot system uses an oversized front sight dot that catches the eye 2.3 times faster than standard three-dot configurations. While traditional night sights require precise alignment of multiple dots, this design simplifies the sight picture to a single focal point. The tritium inserts maintain brightness for 12 years without batteries or external charging, providing consistent illumination when electronic sights fail.

Key Features

• Big Dot front sight with green tritium and orange photoluminescent outline
• Shallow V-notch rear sight with green tritium and white outline
• CNC-machined steel construction with corrosion-resistant finish
• Drop-in installation fits factory Glock dovetails without modification
• 0.140" front sight width optimized for defensive shooting

Field testing demonstrates the DXT2's effectiveness across multiple shooting scenarios. Law enforcement agencies report 40% faster first-shot times during low-light qualifications compared to factory sights. The system excels in home defense situations where quick target identification matters most. Competition shooters appreciate the consistent sight picture that eliminates guesswork during rapid target transitions.
