Built upon decades of military innovation and service, Meprolight’s® high-grade tritium has remained the benchmark by which tritium illuminance has been measured. The Mepro Tru-Dot® family of shotgun sights are the standard by which all tritium pistol sights are measured. Meprolight® utilizes a specially formulated manufacturing process giving you an industry-first brightness from broad daylight to no light and everything in-between. They have been used and trusted for decades. The trust earned has made this family of tritium day/night sights the top choice by OEM manufacturers.


Mepro Tru-Dot® fixed shotgun sights feature an extremely bright 3 white dot for fast accurate target acquisition in the daytime. Both rear and front tritium sources will appear green during lowlight and no light scenarios providing the upmost confidence for you to make hits when it counts.

Premium Swiss-made tritium vials in the front and rear sights allow for low light and no light conditions. Mepro Tru-Dot® sight sets are engineered as a direct upgrade to your factory sights and are designed to fit all holsters.


The Mepro Tru-Dot® family is drop-proof, shock-proof, and built for endless abuse or anything you can throw at it. Their ultralight steel construction features a snag-free design making it easy to quickly draw your weapon. Knowing this gives confidence in any environment you may find yourself.


Mepro Tru-Dot® sights require no batteries. They are always on, always ready, 24 hours a day, 7 days a week, 365 days a year. Tritium illuminance is guaranteed for 12 years. They are maintenance-free and can be installed directly with no modifications to your factory slide.
