Frequently Asked Questions
Which Sig Sauer pistols are compatible with the #8/#8 sight configuration?
The #8/#8 front and rear sight size is compatible with many popular Sig Sauer P-Series pistols, including the P226, P227, P229, and several other full-size and compact models that use the standard #8 sight cut. Always verify your specific pistol's sight size against TruGlo's fitment guide or consult a gunsmith before ordering to ensure proper fit.
How long does the tritium in TFO sights last, and do they need to be charged?
Tritium is a self-luminous radioactive isotope that does not require any external light source or "charging" to glow — it illuminates automatically in darkness through a continuous chemical process. TruGlo's tritium vials are rated for approximately 12 years of reliable glow before the luminosity gradually begins to dim, making these sights a long-term investment for your firearm.
Can I install TruGlo Brite-Site TFO sights myself, or do I need a gunsmith?
Installation typically requires a sight pusher tool or a brass punch and hammer to remove and seat the dovetail-mounted sights. While experienced shooters comfortable with basic gunsmithing can often complete the install at home, it is recommended to have a qualified gunsmith perform the installation to avoid damaging the slide or the new sights — especially important given the precision tritium vials inside the housings.
