Frequently Asked Questions
Which Sig Sauer pistols are compatible with these Trijicon night sights?
These night sights are designed to fit Sig Sauer pistols chambered in 9mm and .357 SIG — however, they explicitly exclude the P938 model. If you own a P226, P229, or similar full- or compact-size Sig in those calibers, these sights are an excellent direct-replacement upgrade. Always verify your exact model and generation before ordering to ensure a proper fit.
How long do Trijicon tritium night sights stay bright?
Trijicon tritium lamps have a rated self-illumination life of approximately 12 years from the date of manufacture. After that period the tritium glow will gradually diminish, though the sights remain fully functional as standard iron sights in daylight. The enhanced daylight dot visibility means you'll get excellent performance around the clock throughout their lifespan.
Do I need a gunsmith to install these night sights?
Trijicon night sights are designed as direct replacements for factory Sig Sauer iron sights, but proper installation typically requires a sight pusher tool or a qualified gunsmith to avoid damaging the sight dovetail or the slide. Professional installation is recommended to ensure correct alignment, secure fitment, and to protect your investment in both the pistol and the sights.
