Description
TruGlo built the Tritium Pro line to take everything people liked about their original tritium night sights and add the refinements that made the TFX Pro series so popular. The result is a front and rear set that reads as clean white dots in daylight and switches over to bright green glow once the sun goes down. The tritium inserts run on their own with no batteries and no need to charge them under a light. When the room goes dark, they are already lit.
What Makes the Tritium Pro Set Work
The front sight carries a white FocusLock ring around the tritium vial, which does a nice job of drawing your eye straight to the dot and speeding up focus. Out back you get a U-notch rear that frames the front sight cleanly, plus an angled forward edge that gives you a ledge to rack the slide one-handed against a belt or boot heel if you ever need to. Both sights are CNC-machined steel wearing TruGlo's Fortress finish, a permanent protective coating that shrugs off oils, solvents, and cleaning chemicals.
Fitment for Your Taurus Mil/Slim
This set (part number TG231T2W) is cut for the Taurus Millennium G2 series, PT111 G2, PT140 G2, and the 709 Slim and 740 Slim. TruGlo notes the G2C and G3 share the same sight cut as the G2, so these physically fit those slides as well, though the G3C is not covered. One thing worth knowing: Taurus has occasionally swapped rear sight heights at the factory to tune point of impact, so on rare guns your zero may land a touch high or low. If that happens, TruGlo stocks alternate-height rears they can swap in.
Getting Them Installed Right
The compact design keeps your factory sight radius and slides into most standard holsters without drama. Owners consistently report the rear is a tight press fit, so a quality sight pusher is the way to go, and a dab of thread locker on the front screw keeps everything put. Both front and rear screws come in the package, and the set is backed by a 12-year manufacturer warranty.

Frequently Asked Questions
Will these TruGlo Tritium Pro sights fit my Taurus G2C or G3?
Yes for the G2C and G3, which share the same sight cut as the Millennium G2 this set is designed around. The one exception is the G3C, which these do not fit. Keep in mind Taurus has occasionally changed rear sight heights at the factory, so a rare gun may print slightly high or low, in which case TruGlo can swap in an alternate-height rear.
Do the Tritium Pro night sights need batteries or charging?
No. The green glow comes from sealed Swiss tritium vials that light up on their own around the clock. There are no batteries to replace and nothing to charge under a light, so they are ready the moment things go dark.
How hard is it to install this TruGlo sight set?
The front sight typically drops in easily, but owners consistently find the rear is a tight dovetail fit that really wants a proper sight pusher rather than a punch and hammer. Both mounting screws are included, and a small dab of thread locker on the front screw helps keep everything locked in. If you do not have the tools, most gunsmiths handle this quickly.
How bright are the front and rear dots during the day?
During daylight they read as clean white dots, with the white FocusLock ring around the front vial pulling your eye onto target fast. The front dot is the standout in bright light, while the rear tritium is more subtle until the light drops. Once it gets dark, all three dots glow bright green for a full sight picture.
