The TruGlo TG231MP1W Tritium Pro night sights bring Swiss-quality tritium illumination to S&W M&P platforms, delivering reliable low-light visibility without batteries or external charging. Built for shooters who need fast sight acquisition in darkness or dim conditions—whether on the range, in defensive training, or in the field—these sights combine proven tritium brightness with features designed for speed and one-handed operation.
What sets the Tritium Pro line apart is the engineering behind the brightness. TruGlo sources Swiss tritium for maximum luminosity and pairs it with a FOCUS-LOCK ring on the front sight, engineered to help your eye settle on the sight picture faster in low light. The rear sight features an angled edge, a practical detail that lets you rack the slide or operate the gun one-handed if needed. The U-notch design keeps the sight picture clean and quick, cutting out the learning curve if you're upgrading from standard iron sights.
These sights are assembled in the USA and finished with FORTRESS FINISH, a protective coating that resists corrosion and wear. The snag-resistant profile fits standard holsters without modification, so you won't need to reholster or swap gear. And because tritium requires no light exposure or batteries, you get constant visibility in any lighting condition—a genuine advantage over photoluminescent-only systems.

Frequently Asked Questions
What S&W pistols do these sights fit?
The TruGlo TG231MP1W sights fit S&W M&P models including SHIELD and .22 caliber versions, but not .22 Compact or C.O.R.E. models. They also fit S&W SD9 and SD40 platforms, except for VE versions. Check your exact model against the compatibility list before ordering.
Do these night sights require batteries or charging?
No. These sights use Swiss tritium, which is self-illuminating and requires no batteries, external light source, or recharging. They glow continuously in darkness and low-light conditions.
Will these sights fit my holster?
Yes. The snag-resistant design is compatible with standard holsters and does not require any holster modifications.
What's the difference between the front and rear sight tritium?
The front sight features green tritium with a white outline for contrast and rapid focus, while the rear sight is green tritium alone. The white outline on the front helps your eye lock onto the front sight picture quickly in low light.
