Trijicon SRO Reflex Sight Review
Long-time red dot sight front runner Trijicon has taken a slight departure from its flagship reflex sight, the RMR Type 2.
The Trijicon SRO is a purpose drive red dot sight focused on design optimized for pistol applications. The SRO is not meant as a replacement or even an evolution of its cousin, the RMR Type 2.
The goal with the SRO is speed. So, if you need speed and want the performance from Trijicon, then this reflex sight might be the optic for you.
Bottom Line Up Front
The Trijicon SRO, is likely to become a favorite for many shooters for one main reason. The viewing window size makes the initial acquisition of the red dot reticle super easy. The red dot seems never to leave the optics window making for faster follow-up shots during rapid-fire situations.
Trijicon has also made it easy to love this sight by keeping the exact footprint mounting requirements as the RMR. Since the RMR footprint is standard among red dot sight and optics, finding a mounting solution for many applications is easy.
Now we know that everyone has repeated several times, including Trijicon, that the SRO is not for duty use. Still, there is nothing about the optic that disqualifies it for such applications.
Food for thought there, if we are to use the ruggedness standard that only the RMR Type 2 can achieve, then that would mean that no other optic is fit for duty use.
So if you are a competition shooter, hardcore plinker, hunter, or all-around gun enthusiast, you will find that the Trijicon SRO is an excellent optic for pistol, shotgun, carbine, and rifle applications.
Top Features of the Trijicon SRO Reflex Sight
The SRO is constructed from 7075-T6 forged aluminum alloy. The T6 tempering of the 7075 aluminum doubles the tensile strength of the untempered 7075. Ultimately this makes for a rugged sight chassis that is still lightweight. The optic weighs only 1.6oz, making it virtually unnoticeable even on a pistol.
The optic sports a large Field of View (FOV) with a sight window measuring .98 x.89 inches. The outer surface of the sight is finished in matte black. The overall length of the sight is 2.2 inches, with a height of 1.4 inches. Most shooters will not find the sights additional real-estate above the slide to be a problem.
According to Trijicon, the SRO is submersible to a depth of 10ft. This waterproof statement is consistent with an IPX8 rating, although Trijicon did not specify the duration of submersion. You should have no problems operating this reflex sight under high moisture conditions at the range or in the field.
The Trijicon SRO is available in three different reticle size options, all utilizing a red illuminating LED.
1 MOA red dot model SRO1.
2.5 MOA red dot model SRO2.
5 MOA red dot model SRO3.
The front lens of the optic is extremely clear, making for a crisp reticle dot and a sharp target image — all of this in a large viewing window, one of the best features of the SRO.
The SRO includes a manual and auto-brightness reticle mode. In the manual mode, there are eight brightness settings. The two lowest settings are night-vision compatible. There is also a setting called super bright mode.
A single CR2032 Lithium coin battery powers the SRO reflex sight. The battery life is listed at three years. Additionally, the battery is top-loaded, so you won’t have to dismount the optic to change the battery.
The operation of the sight is simple and easy with two side-mounted buttons for on/off and brightness settings. The placement of the buttons makes adjustments easy and fast.
The SRO features a lock-out mode that places the sight in auto-brightness mode. You can also use the lock-in mode to keep it on your preferred brightness setting.
To make elevation or windage adjustments, simply adjust the tool-less adjustment screws with a coin or end of a spent casing. Each click of the windage or elevation adjustment equals 1 MOA allowing for precision to mid-ranges. There is noticeable tactile feedback when adjusting the sight for quick and easy zeroing.
There is a total of 150 MOA adjustments for both the elevation and the windage. With 150 MOA, there is plenty of room for adjustment, no matter the mounting situation and application.

Pros vs. Cons of the Trijicon SRO
One of the biggest pros of the SRO red dot sight is the large FOV. This stand-out feature allows for some of our fastest dot acquisitions.
We always appreciate a top-loading battery along with long battery life.
The SRO delivers on both counts here.
The optic has a very sharp viewing experience along with crisp dots, available in three reticle dot size models to meet any application from close quarters to mid-range applications.
If your pistol has irons forward rear sight aperture, you will not likely be able to mount the SRO.
The price. The SRO is at the top of the list regarding price. Although with Trijicon, you can rest assured that you are getting a quality product.
Since the SRO sits forward from the mounting base, it is not recommended that you mount the sight on a pistol or firearm where it will overhang the chamber breach. This limiting factor may force some firearm owners to choose a different red dot sight for a pistol.If you need a side-by-side comparison of MRDS, read our 5 Best Pistol Red Dot Sight Review plus buyers' guide.

Trijicon SRO VS RMR
Again we would like to point out that the SRO is not a replacement for the RMR. The RMR has its place in the market and out n the field that is solidly rooted through years of application. But the SRO shines when it comes to the speed in acquiring the red dot reticle.
Durability: The RMR exterior design, makes it in our opinion, and that of countless others the most rugged reflex sight in the market. Don’t get us wrong the SRO is plenty tough but would be more at home for completion shooting or hunting.
FOV: Unlike the RMR, the SRO has a huge FOV making the acquisition of the dot extremely easy for both the initial shot and each subsequent shot. The dot seems like it never leaves the window!
Size: The SRO has a Larger viewing area than the RMR but they both share the same mounting footprint.
Weight: Along with the increased size of the SRO comes an increase in weight. The SRO is .4oz heavier that the Trijicon RMR.
Battery Location: The SRO is the winner here as the battery well is located at the top, while the RMR requires you to remove the sight to change the battery.
Battery Life: The RMR has a four-year battery life over the SRO’s three-year battery life.

Common Questions about the SRO reflex sight.
Q. Does the SRO use the same RMR plates for the GLOCK MOS?
Yes, the Trijicon SRO has the same footprint as the RMR and uses the same mounting plate and mounting kit #AC32085. The mounting kit is also needed for the Springfield OSP Models as well.
Q. Can I mount the Trijicon SRO on a shotgun?
The SRO is designed to withstand repeated recoil force and would function without any problem on a shotgun, rifle, or carbine. You will need to use a RMR mount appropriate for the specific shooting platform.
Q. Which MOA size reticle is better for a pistol?
This is a question that reddotsightreviews.com has addressed many times. Dot size is going to be a personal preference. Generally speaking, shooters opt for a larger reticle for close-range applications while some shooters prefer a smaller reticle size for precision at further distances. The 2.5 MOA reticle is a good in the middle option.
Q. Do I need to install the sealing plate like on the RMR?
No, unlike the RMR, the SRO is sealed on the bottom as its battery well is located on the top of the optic.
Q. Do I have to dismount the SRO like the RMR to replace the battery?
The SRO battery well is located on the top, unlike the RMR so you will not have to dismount the optic to replace the battery.
