Will this work on a Sig P226 Legion? Expert Answer

Yes, the P226 Legion models E26R-9-LEGION-R2, 226R-9-LEGION-R2, E26R-9-LEGION-SAO-R2, 226R-9-LEGION-SAO-R2, are all compatible with our Romeo1 Pro, Romeo2, DPP, and RMR (Including the Trijicon SRO).

Can the SRO be mounted on a Sig Sauer MK-25 Ca version with loaded chamber indicator? If so, how about with Trijicon suppressor height sights? Expert Answer

The only way the SRO can be mounted on that handgun is to either get a custom adapter made that would replace the rear sight or you would need to get a bridge mount like the UM3 mount. Please email us at techsales@opticsplanet.com so we can confirm your exact handgun model, to see if there are any adapters we offer.

See everything by Matt S., Gear Expert, September 5, 2019
Really great product from Trijicon to cover a different application. I run a RMR on my carry gun and love it. The design that makes it so rugged though makes it a small window compared to other options. But seeing everything is more important than ...

Trijicon SRO by FL Guy, January 29, 2026
⭐⭐⭐⭐ The Trijicon SRO 1 MOA has been excellent on my Glock 34. The dot is crisp and easy to pick up, and it’s been rock solid with no issues so far. Buttons are responsive and well-placed, making brightness adjustments quick and easy. Mounting was st...

Worth it, just get it by Dshep, Verified Owner, November 14, 2025
I’d like to say that this thing is buy once, cry once, but I now have 2. This is without a doubt the best competition-style pistol optic on the market. Extremely rugged, never looses zero. You can beat the heck out of it (I don’t recommend it just in...

Switched from Holosun to Trijicon by HARRY REAVIS, Verified Owner, February 18, 2025
I was a diehard Holosun supporter I had their optics on all of my firearms until recently. I recently purchased a 507Comp for my Staccato P. Took it to the range to sight it in, and to my surprise I was unable to turn it down enough at 7 & 10 yards. ...

Used Product Sent and No Screws by bafflingbs, Verified Owner, September 11, 2025
The SRO deserves it’s high praise, as it’s, in my opinion, the best handgun optic available today. No, it’s probably not the most rugged. But I don’t run my guns over with a truck, nor do I drop it from 20ft. I’m not made of money, and I don’t have s...
