Meprolight Tru-Dot Tritium Green Sight Set for S&W Sigma - Steel Blue

The Meprolight Tru-Dot Tritium Green Sight Set for S&W Sigma delivers reliable low-light aiming when traditional sights fail. Built with self-illuminating tritium gas tubes in both front and rear blades, this handgun sight set gives you a bright green 3-dot sight picture in darkness, fog, smoke, or other low-visibility conditions—no batteries to replace, no switches to toggle. The front sight remains green for contrast against the green rear blade, giving you the sight alignment you need when it matters most.

Meprolight's tritium technology is trusted by NATO forces, U.S. military units, and Israeli defense personnel for exactly this reason: it works when conventional sights leave you shooting blind. The sight set is also immune to weather, gun solvents, and oils, so you don't have to worry about damage from your normal cleaning routine or field conditions. Designed specifically for the S&W Sigma platform, this steel blue sight set replaces your factory sights with a complete front and rear solution.

Whether you carry the Sigma for personal protection, duty use, or sport shooting, low-light accuracy matters. Tru-Dot sights shift the odds back in your favor, giving you usable sight picture in conditions where most shooters are guessing. This is the kind of upgrade that proves its value the moment you need it—or the peace of mind knowing it will work if you do.

Frequently Asked Questions

Will these Meprolight sights work on my S&W Sigma?

Yes. This sight set is engineered to fit the S&W Sigma platform and includes both front and rear sights ready for installation on your handgun.

Do I need batteries or a power source for the tritium sights?

No. Tritium is self-luminous and requires no batteries, switches, or charging. The sights remain functional as long as the tritium gas tubes are intact, making them ideal for carry or home defense where you cannot rely on external power.

How bright are the sights in complete darkness?

Tritium sights deliver a usable green glow in darkness and low-light conditions where iron sights become nearly invisible. The brightness decreases over the tritium's lifespan but remains visible for years of service.

What comes in the box?

The set includes both front and rear sights sized and configured for the S&W Sigma. Everything needed to replace your factory sights is included.
