Frequently Asked Questions
Will these sights fit both the Glock 42 and Glock 43?
Yes. The Meprolight Tru-Dot sights in this listing are specifically designed to fit the Glock 42 (.380 ACP) and Glock 43 (9mm) — two of Glock's most popular single-stack concealed carry pistols. They are not interchangeable with full-size or compact Glock models such as the G17 or G19, so always confirm your model before ordering.
How bright are tritium sights in complete darkness, and how long do they last?
Tritium is a radioactive gas that emits a continuous, battery-free glow visible in low-light and no-light conditions. Meprolight's Hyper-Bright tritium formula is formulated to be among the brightest in the industry. Tritium has a half-life of approximately 12 years, meaning the glow will gradually dim over time — most manufacturers, including Meprolight, back their tritium vials with a 12-year warranty against defects.
Do I need a gunsmith to install these sights on my Glock 43 or 42?
Glock sights are pressed into the slide and require a sight pusher tool or bench vise block for proper installation. While experienced hobbyists with the right tools can install them at home, professional installation by a gunsmith is recommended to avoid damaging the sight or slide. Most gun shops, including Goodland Guns, can assist with installation for a nominal fee.
