Frequently Asked Questions
Will this rear night sight work with my aftermarket front sight?
This is a Glock OEM rear sight sized at 6.5mm, which matches the standard factory sight height used across most full-size and compact Glock models. It will pair correctly with any front sight designed to match standard Glock sight height. If you're using a suppressor-height or adjustable front sight, verify that the heights are compatible before purchasing to ensure a co-witnessed sight picture.
Does this sight fit the Glock 42 or Glock 43?
No — this 6.5mm rear night sight is not compatible with the Glock 42 or Glock 43. Those subcompact single-stack models use a different, narrower dovetail and sight dimensions. Glock offers separate sight options specifically designed for the G42 and G43 platforms. If you own one of those models, be sure to select the correct variant before ordering.
How long do tritium night sights last, and will they need to be replaced?
Tritium is a radioactive isotope with a half-life of approximately 12 years, meaning your night sights will gradually dim over time. Most manufacturers, including Glock, rate their tritium sights for a usable lifespan of roughly 10–12 years under normal conditions. After that point, the glow may become noticeably dimmer, and replacement is recommended to maintain reliable low-light performance.
