Trijicon Bright & Tough Suppressor Sights for Glock 20/21

Trijicon Bright & Tough Suppressor Night Sights

These are serious iron sights designed for shooters who demand performance when the sun goes down. Trijicon's Bright & Tough night sights use self-illuminating tritium lamps to increase night-fire shooting accuracy by as much as five times over conventional sights—and they do it with the same speed as instinctive shooting, without requiring batteries or external power.

Design and Construction

The three-dot sight picture is housed in a robust metal body, cushioned within silicone rubber for shock resistance. This design philosophy reflects decades of real-world testing:

• Sapphire jewel caps on each lamp distribute light evenly and protect against solvents and puncture damage
• Aluminum cylinders provide additional protection for the tritium lamps
• Silicone rubber cushions isolate the lamps from shock and heavy recoil
• Green tritium lamps are warranted for 12 years from manufacture

Suppressor-Height Configuration

These sights are specifically designed to co-witness with suppressors and optics mounted on large-frame Glock pistols. The elevated sight plane ensures your sights remain visible and usable when a suppressor is mounted on your barrel.

• Front Sight Width: 0.144"
• Front Sight Height: 0.403"

Why Choose These Sights

If you shoot your Glock in low light or at night, these sights represent a significant upgrade in capability. They're built to withstand the rigors of serious shooting and backed by Trijicon's reputation for quality and durability.
