Tough and Reliable Construction

Self-illuminating Tritium with Long Life

The sights offer bright aiming references in low or dark situations. Thanks to the tritium-phosphor lamps. Tritium is a self-illuminating element that has a half-life of 12 years. Which in simpler terms means that the posts will continue to glow for the coming 12 years with a very minimal difference in brightness. 

Adding to this feature, Trijicon also covers the tritium-phosphor lamps with a 12 year warranty. The self-illuminating design eliminates the need for any batteries and keeps the sights lightweight. 

Quick and Enhanced Target Acquisition

The big yellow/orange dot on the front sight makes target acquisition extremely fast. Which is an exceptionally helpful feature for high-stress situations. Trijicon HD sights are one of the brightest night sights available on the market today. 

These sights are exceptional for close range engagements due to their brightness and notch/blade size. 

Single-handed Slide Manipulation

The rear sight in this set has been hooked slightly to help with single-handed slide racking. While this feature may not be essential for most users. But nobody knows what’s going to come up in an SHTF situation. 

Single-handed racking helps handle medical emergencies or any other important tasks at hand while keeping you in the fight. 


Like every coin has two sides, almost every product has a few downsides. The Trijicon HD night sights don’t have any significant cons. But rather miniscule considerations to help you with deciding the best uses.

More Expensive than Most Other Sights

Quality often comes at a price. When you’re out looking for a night sight that is trusted by LEO’s, military, and pro tactical shooters. Price is not always a concern. However, if you’re on a tight budget. The Trijicon HD night sight may seem a tad expensive.

Eventually, it’s your need and preference that’ll decide if this is a con. 

Not Best for Longer Range

These sights feature a thick front sight blade that covers a large portion of the rear U-notch. While this is a great feature for quick target acquisition. This will cover your target to a significant extent over longer distances respective to handguns.  

If your purposes include covering longer ranges, you should go for the Trijicon HD XR version. 

Requires Dedicated Installation

Trijicon recommends getting these sights installed by a gunsmith. Which will further depend upon your level of expertise. However, installing these sights will require a proper sight tool and due care. 

Additionally, the rear sight has no windage/elevation adjustments. A slight drawback If you’re looking for them.

Best Uses of Trijicon HD Night Sights

Night sights were designed to be used, well… in the night. But that doesn’t render them useless during the day. The Trijicon HD night sights feature tritium-phosphor lamps that are easily visible in the day and offer astounding visibility and clarity in low light/dark situations.

The first and most obvious use of these sights is defense. It can be home defense, self-defense, or active duty. Especially when the distance of engagement is under 40 yards. 

The big front dot and the rear sights with black outline and a U-shaped notch deliver quick reference points for instantly and accurately slamming copper into a hostile. 

Since handguns are fairly common for EDC self-defense and home defense uses. You can equip your pistol with these sights and a good flashlight. Additionally, the non-dependence of batteries and a half-life of 12 years make these sights ready at any moment.

These HD sights have an anti-glare surface and can be used as leverage to rack the slide single-handedly. Making them suitable to be mounted on handguns intended for SHTF uses. 

As far as competitions are concerned, these sights will work great within the appropriate range as mentioned above. On a side note, these sights are also great for people with weak eyesight.
