Trijicon Sro Review


Optical sights are configured to enable shooters precisely acquire their target, whether in the range or the hunting fields. However, there are some features and activities, on the optical sights that can compromise its functionalities, such as the constant dropping of the weapon, lack of parallax, and a sight’s heavyweight.

Optical sight hunting is not exactly a walk in the park because some of the reviews posted by users can be pretty discouraging yet the sight’s work great. Trijicon SRO has been ranked as a recreational optical sight or a sight that is convenient for use with a competition gun by some enthusiasts. But according to Trijicon the sight comes out as one to be used by professionals and has borrowed some of the RMR’s best features.

Enthusiasts appreciate that sight has incorporated a wide field of view, complete with a clear dot, but they have concerns about its durability stating that they would prefer the RMR over the SRO as it features a robust build. Well, according to the manufacturer, Trijicon Sro, was forged from RMR’s 7075, T-6 aircraft grade aluminum, meant to protect the lenses and the equipped electronics, a feature that makes it durable at least when compared to other red dots in the market.

Given the controversy between the users and the manufacturer, we decided to dig into the features of the Trijicon Sro and establish whether it is a professional optical sight or just another basic unit, read on.

Trijicon Sro Review and Breakdown

Trijicon sro has been specially configured for use with pistols, the unit can also easily be mounted on the red dot ready pistols, and is additionally compatible with the RMR mounts. The Hood protecting the glass and the other electronics is made of durable aluminum housing, and you can, therefore, expect the glass to remain highly functional even when the weapon suffers impact.

The 7075-T-6 aluminum housing is sturdy and will, therefore, not transfer the impact to the glass, and while in the field you can expect the sight to give you all the juice needed to accurately acquire your target given the incorporation of the 3-year battery life. And to make it more versatile and functional Trijicon Sro has been made compatible with the suppressor height iron sights.

We are however not convinced that the relevant settings are easy to adjust because most of the modern sights come equipped with buttons, so all you have to do is either use a switch or the press buttons. But for the Sro, you have to find an equipment like maybe a coin to perform some of the basic adjustments.

And when it comes to the brightness modes, users can alternate between the manual and the automatic LED brightness modes. The large objective lens helps provide a wide and unobstructed field of view, while the intense red dot is not only easy to track but also easy to recover. The sight works best in applications where speed and quick dot recover are of the essence.

What we liked;

  • The aluminum body protects the lens thus remains functional for extended periods
  • Trijicon Sro is equipped with a durable battery
  • The incorporated objective lens diameter is wide enough for enhanced visuals
  • Works exceptional well when used with the pistol
  • The clear crisp dot encourages quick dot recovery
  • The sight is compatible with the suppressor heights iron sights

What we didn’t like;

  • Limited application “best used with pistols”
  • Adjusting the settings during use is hectic thus eats up a lot of time

Trijicon Sro Features

Optical performance

Trijicon Sro’s optical performance is quite impressive, and we begin with the fact that it has been equipped with a large objective lens diameter. The latter means that users can expect to be provided with clear images even when engaging targets in low light conditions; even better is that they can use the higher magnifications for longer, as the already available light diminishes. The large objective lens diameter makes the unit highly functional when looking for a sweet spot faster.

The unit additionally offers a rather clear and crisp dot, which is not only fine-tuned but has been coupled with the clear lenses at the front part. The above consequently offers a clear sight picture, complete with a crisp dot. Still, on optical performance, the unit comes equipped with up to 8 brightness settings; two that are for night vision and one that is super bright.

Trijicon Sro is submersible up to 10 feet deep, a feature that qualifies it for professional applications.


According to Trijicon, the Trijicon Sro was specifically made for use with pistols, but you must note that it will comfortably fit on the different red dot ready brands in the markets. And as regards use, the unit is incredibly efficient when used for target shooting, and in competition, the above is because of the equipped Button “Lock-In” mode designed to secure the user-chosen brightness setting.

Hunters can also benefit from the unit’s effective red dot thanks to the incorporated Button “Lock Out Mode” which is ideal for hunting and for use with the carry handgun.
