Frequently Asked Questions
Are these sights a direct drop-in fit for the FN FNX-9?
Yes, the TruGlo TFX Pro sight set is specifically designed and machined to fit the FN FNX-9 pistol. No gunsmithing or modification to the slide is required for most installations, though a sight pusher tool is recommended for clean, damage-free installation.
How long does the tritium illumination last?
Tritium is a self-luminous radioactive isotope with a half-life of approximately 12 years. In practical terms, you can expect strong nighttime glow for roughly 10–12 years before the illumination noticeably dims, making TFX Pro sights a long-term investment for your FNX-9.
Can these sights withstand ultrasonic cleaning and solvent exposure?
Absolutely. The TFX Pro's illuminating elements are fully encapsulated in a virtually indestructible capsule that is impervious to oils, chemicals, cleaning solvents, and even ultrasonic cleaning processes — so your regular maintenance routine won't damage the sight's performance or longevity.
