Shell Ejection Port Jam
The Trijicon's overhang lens frame can get in the way of shell ejection. Depend on where the ejection pattern angle is, and how fast the slide is cycling. There is a chance that the overhang can jam the slide.
It doesn't happen a lot, but Yes, it can be one of Trijicon SRO problems.
Trijicon SRO Lens Frame Isn't Duty Grade
The Trijicon SRO's thin lens frame isn't the same as the original RMR with that beefy rounded corners to absorb heavy point impact.
The Trijicon SRO is a range and competition optic built with the same 7075 T6 aluminum body as the RMR. It's great for many shooting applications.
Brightness Lock Out Mode
Trijicon SRO features auto dimming feature to save battery. The optic features Lock Out mode, Lock In mode and User setting mode that most users don't spend much time investigating how it actually works.
Trijicon SRO's default mode is the automatic mode, which means the optic AUTOMATICALLY adjusts to ambient light. This is where many SRO users get frustrated when the reticle always dims after use.
The newer Trijicon RMR HD fixes the issue by using a forward sensor that automatically adjust the brightness based on the lighting conditions from the target.
The Manual Brightness Lock In Mode allows the user to set a brightness setting from 1 to 8, then hold either button for 3 seconds to lock the setting. The dot will blink to indicate you did it right.
The Lock Out Mode is basically automatic mode with manual adjustment with a 16.5 hour reset timer.

A drop in battery voltage can cause the Trijicon SRO to shut off, though this typically indicates an issue with the battery itself. Simply just swap out the battery and you are good to go.
One positive feature the Trijicon SRO offers is the top loading battery access, so the user doesn't have to demount the optic or re-zero.
While most people think the reticle has problem displaying a crisp dot. The problem is actually people's vision. Most people have astigmatism, but they don't know it.
Most red dot sight will have this problem especially when using a 1 MOA or 3 MOA or 6 MOA. If you have astigmatism, the Trijicon SRO's dot will definitely look blurry and smeared because the smaller the dot the more emitter starburst there is.
Trijicon SRO offers a 5 MOA dot model, which is a better choice for pistol red dot shooters as well as using it as an offset optic on a carbine or shotgun.
Another issue could be dirty lens emitter
Open Emitter Issue
Most open emitter red dot sight design attracts dirt. Sometimes it can fog up the emitter like this, or if mud or water get in there:
If the user drops the gun with the Trijicon SRO in mud, snow, or a sand pit and debris enters the optic, they must clean the lens before the reticle can clearly project.
This is where enclosed emitter red dot sights are getting more popular. Optics like Holosun 509T, Aimpoint ACRO, the new Trijicon RCR and others are coming up with better projects to prevent this problem.
