- Green front and rear tritium dots for fast, intuitive target acquisition

Who This Is For
These sights are purpose-built for S&W M&P owners who carry for personal defense, duty use, or home protection — anyone who needs a dependable, no-maintenance sighting solution that performs just as well in a dark hallway as it does on a sunlit range. They're equally at home on a nightstand pistol or a daily carry gun, giving both experienced shooters and first-time handgun owners a meaningful upgrade over factory sights without requiring gunsmithing expertise.

Frequently Asked Questions
How long will the tritium in these sights continue to glow?
Tritium is a mildly radioactive gas that naturally loses luminosity over time through radioactive decay. TruGlo Brite-Site tritium sights are rated for approximately 12 years of reliable glow, after which brightness gradually diminishes. Even past that point the sights still function as standard three-dot sights during daylight conditions.
Will these sights fit all variants of the S&W M&P pistol?
The TG231MP is designed to fit the standard S&W M&P lineup including full-size and compact models that use the factory M&P sight cut. They are not guaranteed to fit the M&P Shield, M&P 2.0, or M&P 380 EZ without verifying the sight dovetail dimensions — consult TruGlo's fitment guide or contact us at Goodland Guns to confirm compatibility with your specific variant before ordering.
Do I need a gunsmith to install these night sights?
While many experienced shooters install dovetail sights at home using a sight pusher tool, handgun night sight installation can require specific tooling and a precise fit to avoid damaging the sight vials. If you're not comfortable with the process, we recommend having a qualified gunsmith perform the installation to ensure the sights are properly seated and zeroed for accurate shooting.
