What is tritium and is it safe?

 

Simply put, tritium is one of the most powerful technologies TRUGLO utilizes to make sights bright. It does not need batteries or need to be charged with light. It provides a constant glow for years. This makes it a great technology for emergency equipment like illuminated exit signs, watch hands, and handgun sights.

Tritium is a radioactive isotope of hydrogen. It gradually breaks down and decays into helium. As it decays, a small about of energy is gives off. The tritium vials found in gun “night sights” and wrist watches contain a small amount of tritium gas and phosphorus or other photo-sensitive materials. As the tritium breaks down and gives off energy. This energy (ionizing radiation) excites the phosphorus and causes it to glow. This creates a constant and steady glow for years.

The rated half life of tritium is approximately 12 years. This means that after twelve years, handgun sights will be approximately half as bright are when there were first sent to the dealer.

Tritium gas occurs naturally in the atmosphere. It is generally considered to be harmless, except in very high concentrations. The amount of tritium used in in wrist watches and handgun sights falls well below the amount considered to be harmful.

If a tritium vial ever breaks or leaks (which is rare), there is no required clean-up or precautionary handling procedure. Tritium is a pressurized buoyant gas that quickly dissipates and returns to the atmosphere.
Facilities that work with tritium and install tritium vials are heavily regulated by the United States Nuclear Regulatory Commission (USNRC) to ensure that maximum tritium quantities in a facility are within safe limits and that all tritium-related products are installed and maintained in a safe manner.

Replacement Battery Cap

A replacement battery cap is available for $7.95, including postage. Please be sure to specify which model scope, or Red Dot sight you own and if you require a black, or camouflage cap. Contact TRUGLO customer service and this can be taken care of over the phone with a credit card.

Sights for S&W® M&P Shield California Compliant Models

Our Smith and Wessson M&P series sights are designed as a direct replacements for factory M&P sights. (Full size, compact, Shield, etc.)

The California compliant M&P shield models feature a loaded chamber indicator (LCI). This LCI partially obscures the sight picture of the factory sights. TRUGLO sights are based on the height of the factory sights (to fit standard holsters, etc.) and experience the same issue.

There is not currently a California specific sight model to circumvent the issue of the LCI partially obscuring the front sight.

 

 

Replacement Flip-up Lens Caps

Replacement flip-up lens caps for Scopes and Red Dot sights are available for $7.95 for a single cap and $10.95 for the set, front/rear, including postage. Be sure to specify which model red dot sight you are ordering these for when contacting TRUGLO customer service. If you have a 2X red dot with 42mm oblective, ,or 40mm red dot, please indicate when ordering.

Sig® P320 X-Series Sight Set Compatibility

Unfortunately our handgun sight sets are not compatible with any of the Sig Sauer P320 X-Series pistols. This includes the X5, X5 Legion, X-Carry, and X-Compact. This is due to these firearms utilizing a rear sight optic plate where the rear sight is attached to the optic plate, i.e. no rear sight dovetail.

 

However TRUGLO offers a Fiber-Optic Pro front sight only compatible with the Sig Sauer P320 X5 (includes X5 Legion).

Replacement Windage and Elevation Cap

Replacement windage and elevation caps are available for $7.95 for the set, including shipping,. Please contact TRUGLO Customer Service and be sure to specify which model scope or sight you own and if you require black or camouflage caps.

Why is my shotgun front sight bead not aligned?

Depending on where the threads begin on the barrel and the sight, there may be an alignment issue when the sight is snugged into place. When there is a final alignment issue, a gunsmith can use various material(s) to backfill the original hole, to get the sight to align and secure. It is not advised to attempt this if you are not familiar with this technique as the material used can be difficult to remove.

 

TRUGLO recommends all sight installations to be performed by a professional gunsmith with sight specific installation tools.
