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.
