Holosun 508T – Best Overall

Img Referenced @inforce01

The Holosun HE508T is a solid Titanium made red dot optic for the Glock, which is about 30% tougher forged 7075 T6 aluminum optic

This means it’s significantly stronger than the old school Trijicon RMR.

Besides the beefy outer body construction, the optic also has the longest battery life up to 100,000 hours using a single CR2032 battery, which is 5.5X more than the Trijicon RMR.

In addition, the solar panel provides the optic with fail-safe battery source so it will always remain on.

But there is more…

The optic also feature Holosun’s Shake Awake technology, which activates the optic when it senses motion, and it turns off when remaining static. This feature saves battery juice even more and turns on based on the last setting recall.

Best for conceal carry because it’s the most durable optic, which also the width doesn’t stick out too much.

Holosun 407C – Most Affordable

Holosun 407c on glock 19

The Holosun 407C is the first micro size red dot from Holosun. The optic is solid and durable, and it shares the same mounting footprint as the Trijicon RMR. For all RMR users, you don’t need to worry about Compatibility issues.

If the mount or the handgun slide can accept an RMR, then you can use the HS407C. The 407C is the base model, and it is the most affordable option (under $280)

It features the MOTAC techology, and core features that got HS407C so popular. If you’re looking for an all in one package for a super durable miniature red dot without spending big money, the HS407C is the product you will not regret buying.

Holosun 507K – For Conceal Carry

The HE507K is the dedicated model for conceal carry users. The optic is slightly smaller than 407C as far as width, and its great for sub-compact and full size pistols. Is this really necessary to buy?

When you already have higher end red dots… it’s up to you. What’s unique with the 507K is the new side battery access design, so the user doesnt have to remove the sight to replace the battery everytime.

Weighing only 1 oz, which is about 50% lighter than the HE407C. For conceal carry people, shaving down any weight is a plus. The overall size reduction is one key buying decision for some optic users, and it really doesnt make much difference, in fact, a bigger optic is better for picking up the reticle faster and easier.

As far as durability goes, the optic is as strong as an HE407C or Trijicon RMR, made with 7075 T6 aluminum with the same amount of mil spec level quality. The optic is still new on the market, and let’s see how this thing performs.

If you had to pick a red dot for a carry gun, I would personally recommend going with the HS407C or HS508T instead as they have been proven to last for many years, and people trust it.

Other Trijicon RMR Alternatives

The Trijicon SRO is an upgraded model of the RMR. Yes it’s still a Trijicon product, but SRO’s enlarged lens window has solved the small window dot tracking issue, which people love about this new optic very much.

The Trijicon SRO has many new features, but the most important thing you need to know is that this optic has the same mounting footprints as the Trijicon RMR, so you don’t need to worry about any Compatibility issue.

New Holosun Reticle Patterns Trijicon RMR Doesn’t Offer

Referenced SuperSetCA (Watch Reviews Here)

Many micro red dot sights on the market in the past and now offer the traditional center dot reticle from 1 MOA to 6 MOA.

The Holosun 508T now offers a 2 MOA center dot reticle (green or red) with a 32 MOA ring for faster target acquisition and long range hold over points.

Trijicon RMR or even the SRO still don’t offer that, which we expect to see in the future.

The benefit of having the chance to alter between 2 MOA to 32 MOA ring reticle on the 50T is so the shooter can pick the ideal reticle for the job at hand.


How Many G’s Can Holosun HS508T Hold?

Holosun 508T the top pick on our list, and it’s built to survive 5000G force. To put things into perspective, a 50 BMG is about 1500G, and the 508T can hold zero almost 4X more regardless of the recoil.

If you’re shooting anything lower than a 50 BMG, you never have to worry about optic losing zero due to repeated recoil.


Titanium Housing Stronger Than 7075 T6?

7075 T6 aluminum belongs to the aluminum alloys classification, and the grade 5 titanium belongs to the titanium alloys.

Titanium is stronger than 7075 T6 as far as hardness and tensile strength, almost 2X more.

Titanium has a very high melting point up to 3000 degrees F, which makes a good optic for mounting on handguns and AK gas tube that gets super hot.

According to Holosun’s official website, the Grade 5 titanium produces unparalleled strength and durability, and it’s 5X the fatigue strength of 7075 T6 aluminum & lighter weight.


Basic Optic Operation – Which One Is Better?

Trijicon RMR and Holosun micro red dot have the same mounting footprint, and it can go on many different guns. As far as basic operation, both are equally simple to use and feel similar.

The overall feel of the RMR and Holosun felt the same, and tweaking the brightness adjustment & MOA rotation, they feel very familiar.

What’s cool about the 508T is its ability to auto shut off when it remains static. Trijicon RMR doesn’t have that type of technology, and no matter which one you pick, both optics work well and there is no reason to own one but not the other.
