Frequently Asked Questions
Which SIG Sauer P-Series pistols are compatible with these Meprolight night sights?
These Meprolight Tru-Dot sights are designed to fit SIG Sauer P-Series pistols chambered in 9mm and .357 SIG, including popular models such as the P226, P229, and related variants. Always verify your specific model and generation against Meprolight's fitment chart or contact Goodland Guns before purchasing to ensure compatibility with your exact pistol.
How long do the tritium inserts last, and can they be replaced?
Tritium is a mildly radioactive gas that naturally decays over time. Meprolight's tritium vials typically maintain optimal brightness for approximately 12 years from the date of manufacture. After that period, the sights will still function as standard iron sights in daylight, but the self-illumination will dim significantly. Tritium replacement generally requires sending the sights back to the manufacturer or a certified service center.
Do these sights require any special tools or gunsmithing to install?
Meprolight Tru-Dot sights are designed as direct replacements for factory SIG P-Series sights and can typically be installed using a standard sight pusher tool. Minor fitting or adjustment may be required depending on your specific pistol's tolerances. If you are not experienced with sight installation, having a qualified gunsmith perform the swap is recommended to avoid damaging the sights or the slide.
