AmeriGlo CAP GRN Tritium Night Sight Set for Glock 20/21

The AmeriGlo CAP (Classic Ameriglo Profile) sight set with green tritium lamps provides a traditional three-dot sight picture optimized for Glock 20 and 21 models. Swiss-made tritium inserts glow continuously in low light without batteries or external charging, maintaining visibility for 12+ years. The green front and rear dots deliver fast target acquisition in all lighting conditions.

Machined from steel with a matte black finish, these sights install directly into factory Glock dovetails using a sight pusher tool (front requires staking). The CAP profile matches Glock factory sight height for consistent point of impact with standard loads. White outlines surround the rear tritium lamps for enhanced daylight visibility. Compatible with Glock 20 and 21 (all generations).
