Mfr: TRIJICON – -( Nighttime and low light shooting tests prove sights equipped with these glowing dots are easier to see and more accurate than instinctive shooting with standard black sights. Rugged, heavy duty, Traser®, luminous, 3-Dot tritium lamps provide their own long-lasting energy source. Lamps are mounted in silicone-sealed, metal cylinders to give maximum protection from breakage or leakage. Polished sapphire, crystal windows give a bright, crisp and perfectly round aiming dot in low light. Inlaid white rings around each sapphire make the sights appear as standard white dots in daylight. Very narrow blades do not have the white ring and will look more like a plain black blade in daylight. Most can be installed in factory dovetail or sight base. Glock® models require use of special Trijicon installation tools to prevent sight damage.

The First Choice Of Major Handgun Manufacturers
Featuring glowing tritium-filled lamps for a distinctive shooting
picture in any light, Trijicon Bright & Tough™ Night Sights bring the
advantages of self-illuminating technology to sidearm users.
These three-dot iron sights increase night-fire shooting accuracy
by as much as five times over conventional sights – with the same
speed as instinctive shooting – and without the need for batteries.
In addition, they feature a white ring around the glowing dots for
unsurpassed daylight visibility.

Highly effective in close-quarters, Trijicon Night Sights are widely
used in military applications, home defense, as well as standard
issue with hundreds of police departments and federal agencies.

What is Tritium?:
Tritium is a radioactive isotope of hydrogen. It is an odorless, tasteless, colorless gas that reacts with the human body in the same manner as natural hydrogen. Beta rays from the tritium hit phosphors to create the glow you see. Tritium has a half-life of 12.5 years, which means that in that time the lamp will be half as bright as it originally was.

Is tritium harmful?
According to documentation by health physicists in statements on file at the U.S. Nuclear Regulatory Commission (NRC), it would take the simultaneous rupture of 10,000 of these small glass capsules in a small room 10 foot by 10 foot to potentially constitute a radiation health hazard. For this reason, customers need not be concerned about the potential risk of the night sight system. Furthermore, our front sight is 0.018 curies and the two rear sight dots are 0.018 curies each. A complete sighting system is 0.054 curies. This is less than many tritium watches, which have up to 0.200 curies or roughly four times as much radioactivity. In addition, the weapon is not as close to the body, and in less constant use than a watch.

Trijicon Night Sights are the best pistol sights on the market. I have them for my Glock 19.
