Big Window Without Losing The Dot
The primary features of the Trijicon SRO is the window size.
Since many shooters try ways to improve pistol red dot tracking plus practice to get good, and some just struggle.
The Trijicon SRO is here to fix that problem!
For the most part, shooters generally miss the dot because they are just "a hair" off center, then the dot disappear off the edge of the frame.
With practice, shooters can get good at picking up the sight fast with the SRO, but still requires practice.
The SRO's large viewing window has no problems finding the red dot reticle right off the draw, on a presentation without any extra training.
Follow up Shots
Harder recoil guns and muzzle flip can make the dot disappear during fast follow-up shots.
With proper technique the shooter can maintain good grip, trigger control and get back on target consistently having the dot reappear right in front the shooter's eye even for crosseye dominant shooters.
With the larger window, the chances of losing the dot is significantly less than small optics.
Same RMR Mounting Base
The Trijicon SRO has the same RMR mounting platform.
So if your handgun slide has a cut for an RMR, then you can mount the SRO without any problem. The same adapter plates and use for the RMR are gonna look perfectly with the SRO.
In addition, you can mount the SRO on various mounts for rifle applications.
Dot Size Options
Referenced From Trijicon
Based on my testing, the 5 MOA is the way to go for pistol applications because it's just big enough for your eyes to pick up and big enough to reduce starburst for anyone with astigmatism.
The 1 MOA dot is better for rifle applications as an offset red dot.
We have an article on the site that goes in-depth comparing 3 MOA and 6 MOA red dot, please click here to learn more.

Ejection Port Overhang
One thing to be aware of is the SRO optic could cause ejection malfunction.
Because the front of the optic overhangs the ejection chamber will cause the pistol to malfunction.
The optic weight 1.6 oz with battery installed. The weight feels the same as an RMR.
It feels comfortable when you pick it up, and it will not be a weight burden.
The Trijicon SRO lasts about 3- years with 1 CR2032 battery. What's new about it is that this optic is its top battery loading design without removing the sight like the RMR.
Top Battery Access Without Removing The Sight
One of the biggest features besides the enlarged window is the top battery loading design like the Leupold Delta Point, so you never have to remove the sight again to swap battery.
I often hated replacing the battery because I had to find my tools to remove the sight first. This new design completely eliminated that problem, and no re-zero is required.
Trijicon SRO Parallax?
The SRO is a parallax free optic at far distance, there are still a slight parallax when the target plane is at close range distance.
The shooter will benefit from the advantages of using the reflex sight, regardless of your body position if you can put that red dot in transpose it over your target.
Lock Out Mode & Brightness Setting
There also new illumination options including 2-night vision modes. But there’s also a couple of new modes of operation, the first one is "Locked Out".
It means is that the SRO’s going to use its auto-brightness mode, it will detect the ambient light and sets the dot an appropriate level.
In a lockout mode, you can tell it to do the auto adjust only until you unlock it. You can also use the "Lock In" mode if you would prefer to have your SRO set at say brightness level 6 and you don’t want to mess with auto brightness and you don’t want to risk the dot being adjusted by accidentally bump into the buttons.
You can lock that setting in so that you know it's going to be a brightness level 6. Just like the RMR, the 2 brightness settings and these new modes of operation are going to be controlled by these Bay very easy to use buttons on the side of the unit.
Trijicon SRO VS. Others Comparison
Essentially it's just like an RMR but with a bigger window and it sits slightly taller so you don't miss the dot on the top of the lens frame.
- Less time finding the dot
- Good sight alignment with most pistol grip including Glock
- Easier while shooting on the move
- Reacquire the dot after every shot
The sight held the zero and I gotta tell you this feels better than the RMR and DeltaPoint.
Final Verdict - Buy Or NO?
- Enlarged window for easier dot tracking
- Same RMR mount footprint
- Top battery access without sight removal to replace battery
- 5 MOA option is the best for dot clarity
- Solid build quality
- Large lens window overhang could jam on some pistol over the ejection port
- Elevation and windage adjustments don't give positive click feedback
- Lens hood not rated for duty use like the RMR
There are so many new open reflex red dots out there on the market, and the Trijicon SRO is definitely a must have for competition shooters and range plinkers.
If you have to pick a large window pistol optic, the Trijicon SRO is IT!
As far as duty usage goes, the SRO is not suited for conceal carry or duty use because the lens isn't made to withstand heavy impact as the RMR.
