Trijicon® Suppressor/Optic Height Sights - Glock Large Frames GL204-C-600689

Large-frame Glock models deserve the same suppressor-ready sight solution that compact and standard-frame Glocks have been running for years - and the Trijicon Suppressor Height Sights Glock GL204-C-600689 delivers exactly that for the big-bore and large-frame Glock configurations that shooters run suppressed. These are purpose-built Trijicon Suppressor Height Sights Glock for models 20, 21, 29, 30, 36, 40, and 41, including S and SF variants — the full range of large-frame Glock configurations in a single sight set.

The best Glock suppressor height sights give you a clear sight picture over a suppressor body without any compromise in sight alignment or sight picture quality. Standard-height sights on a suppressed Glock disappear behind the suppressor body in a way that makes proper sight alignment impossible - forcing awkward workarounds that are not acceptable for a defensive or duty pistol. The elevated profile on the GL204-C-600689 restores a natural, aligned three-dot sight picture whether the suppressor is attached or not.

The suppressor height sights Glock three-dot tritium system increases night-fire shooting accuracy by up to five times over conventional sights at the same instinctive shooting speed - without any batteries or activation required. Tritium-phosphor lamps glow continuously in complete darkness through passive tritium decay, keeping the three-dot sight picture visible and fast in the low-light conditions that defensive shooting regularly demands. Green lamps are warranted for 12 years from the date of manufacture.

Each lamp is capped with a sapphire jewel to ensure even light distribution and protect against solvents and punctures. Silicone rubber cushioning absorbs shock through heavy recoil. Aluminum cylinders protect the tritium lamps from harsh cleaning solvents and hard impacts through regular carry and use.
