The Meprolight Tru-Dot 1911 Auto (Fixed Wide Tenon) is a green/green tritium night sight set built to upgrade the standard irons on Colt 1911 Government and Commander models. Instead of relying on ambient light to find your dots, tritium does the work for you, glowing steadily so all three reference points line up the same way whether you're at the range on a bright afternoon or clearing a dark hallway. The front dot runs a touch brighter than the rears, which naturally pulls your eye to the front sight where it belongs for a clean, fast aim.
Meprolight has been supplying tritium sights to military and law enforcement for decades, and the Tru-Dot line is known for being some of the brightest tritium sights out there. The self-illuminated design means no batteries, no switches, and nothing to charge. You get a maintenance-free glow that holds up in all weather and lighting. The rear notch and front post are built tough and finished to resist scratches and corrosion, so they hold up to years of holster wear and hard use.
This particular set uses the .125" wide tenon front sight, which is the stake-on style found on Colt Series 80 and 90 guns. The wide tenon gives more surface area than the older narrow tenon setup, making for a more secure hold when installed correctly. The rear is cut for the standard Colt dovetail and drifts in for windage. Staking the front sight properly calls for the right tool to avoid stressing the tritium vial, so most folks have a gunsmith handle the install unless they're set up for 1911 sight work.
Backed by Meprolight's 12-year usable illumination warranty, this set is a straightforward way to add real low-light capability to a carry or nightstand 1911 without turning it into a project gun.
It's cut for Colt 1911 Government and Commander models using the .125" wide tenon front and the standard Colt rear dovetail, which covers Series 80 and 90 guns. Older Series 70 pistols use a narrow tenon and won't accept the wide tenon front without gunsmith work. If you're running a clone or a different brand of 1911, measure your tenon and check your rear cut before ordering.
No. The Tru-Dot sights use tritium, which glows on its own with no batteries, switches, or charging. That steady self-illumination works in all weather and light conditions, and Meprolight backs the usable glow with a 12-year warranty.
The rear sight drifts into the dovetail for windage, which is manageable at home with a sight pusher or brass punch. The front is a stake-on wide tenon, and staking it correctly takes the proper tool to avoid stressing the tritium vial. Most people have a gunsmith handle the front unless they're already set up for 1911 sight work.
The front dot is designed to run slightly brighter than the rears. That subtle difference naturally draws your eye to the front sight for faster target acquisition, while all three dots still line up into one clean reference in the dark.
