Frequently Asked Questions
Will these sights fit both the Glock 42 and Glock 43?
Yes. The Meprolight Tru-Dot Night Sights are specifically designed to fit both the Glock 42 and Glock 43 pistols. These compact, single-stack models share compatible sight dimensions, making this a direct replacement for the factory-installed sights on either firearm. Always confirm your model before installation.
How do tritium night sights work, and do they require any charging or batteries?
Tritium is a naturally radioactive isotope of hydrogen that emits a low-level glow through a process called radioluminescence — no batteries, UV charging, or external light source is ever required. The Tru-Dot's tritium vials are sealed in shatterproof borosilicate glass and glow continuously 24/7 for the lifetime of the sight, typically around 12 years before noticeable dimming occurs.
Are these night sights difficult to install on a Glock 42 or 43?
Meprolight Tru-Dot sights are designed as direct replacements for OEM Glock sights and can be installed with a standard Glock sight pusher tool. While minor fitting adjustments may be needed, most gunsmiths or experienced pistol owners can complete the installation quickly. Professional installation is recommended to ensure correct torque and zero retention.
