Frequently Asked Questions
Will these sights fit both the Glock 42 and Glock 43?
Yes. The Truglo TFX sights with part number TG13GL3A are specifically designed to fit both the Glock 42 and Glock 43 platforms. They are a direct drop-in replacement for the factory sights and require no frame modification. A standard sight pusher tool or professional gunsmith installation is recommended for best results.
How long does the tritium illumination last?
Tritium is a mildly radioactive gas that naturally decays over time. In TFX sights, the tritium vials provide reliable self-illumination for approximately 12 years before the glow begins to noticeably diminish. During daylight hours, the fiber-optic element takes over, making these sights exceptionally bright in virtually all ambient light conditions.
Are TFX sights better than standard fiber-optic or plain tritium sights?
TFX sights offer the best of both worlds. Standard fiber-optic sights are excellent in daylight but offer no illumination in the dark. Plain tritium sights glow at night but can appear dim in bright outdoor conditions. TFX sights combine both technologies so the sight is always at peak visibility — fiber-optic brightness in the day and tritium glow at night — making them a superior choice for everyday carry and defensive use.
