Frequently Asked Questions
Will these sights fit my Glock 43X or Glock 48?
The XS F8 Night Sights in this listing are specifically designed and sized for the Glock 42 and Glock 43. While the 43X and 48 share a similar frame profile, their sight dimensions may differ. XS Sights offers model-specific variants for those platforms, so be sure to verify compatibility before ordering.
How long will the tritium inserts remain visible?
Tritium is a radioactive gas that naturally decays over time. XS Sights tritium inserts are rated to provide useful glow for approximately 12 years under normal conditions. After this period, the sights will still function as standard iron sights in daylight, but the low-light glow will gradually diminish.
Do I need a gunsmith to install these sights on my Glock 42 or 43?
Installation requires removing the factory sights, which are typically press-fit into the slide. Most experienced DIY shooters can install them at home using a sight pusher tool, but if you're not comfortable working on your firearm, professional installation by a qualified gunsmith is recommended to avoid damaging the slide or new sights.
