TruGlo TFX Pro Tritium/Fiber Optic Sights Glock 42/43

TruGlo TFX Pro Handgun Sights for Glock Slimline Models

The TFX Pro represents the pinnacle of day/night sight technology for compact, carry-oriented pistols. This is a sight system engineered for shooters who refuse to compromise on reliability, visibility, or accuracy.

How It Works

TruGlo's hermetically-sealed design combines tritium and fiber optic elements in a virtually indestructible capsule. Tritium provides passive illumination in low-light conditions without batteries. Fiber optic elements gather ambient light for exceptional daytime brightness. Together, they ensure a bright, visible sight picture 24/7.

Key Features

• Contrasting orange ring on the front sight accelerates target acquisition and helps your eye focus rapidly on the front sight
• U-notch rear sight design provides quick, accurate sight alignment
• Aggressively angled rear sight edge enables emergency one-handed operation—critical in defensive scenarios
• Chemical and shock-resistant capsule protects illuminating elements from impact and harsh environments
• CNC-machined steel construction with rust-proof Fortress finish for durability
• Snag-free design suitable for carry and tactical use

Fit and Function

These sights are specifically engineered for Glock Slimline models including the 42, 43, 43X, and 48. Installation is straightforward for those with basic gunsmithing skills, or have a qualified armorer handle the work.

The Bottom Line

If you carry a compact Glock and demand sights that perform in any light condition, the TFX Pro delivers the reliability and visibility professionals expect.
