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).
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.
It will require an adapter as the X-Carry is cut specifically for the Romeo1 red dots. We unfortunately do not currently offer a mount that will adapt your slide to accommodate a RMR pattern red dot.
Yes, you can use MPN: 49532 found here:

You can mount this to the DVC-3 by using MPN: 49517 found here:

In regards to how its going to look to you because of your astigmatism, there is unfortunately no good way to tell. Because everyone's eyes are different, your eyes may see the dot on the SRO perfectly clear and crisp or it may be blurry. There is yet to be a way and may never be a way to verify which red dot is going to be best for people with an astigmatism like you and I.
This will not fit as that gun is only cut and drilled for the Sig Sauer red dot sights. There is no adapter plate to convert to RMR/SRO at this time.
Springer Precision has adapter plates for X-5 to mount an RMR.
The Trijicon SRO MOA Red Dot Sight is not compatible with the FN Reflex. The FN Reflex will only fit optics that use the RMSc or K footprints. Direct fit options include the Sig Romeo Zero, Shield RMSc, Holosun EPS Carry, Vortex Defender CCW, Holosun 407K/507K & more.
The P320 X5 Legion is compatible with the Leupold Delta Point Footprint. So the Trijicon SRO MOA Red Dot Sight will not fit.
If you have a Springfield XD Mod 2 OSP, you will not be able to install this optic as it is too large for the optics the Mod 2 OSP was intended to fit. No plate exists to allow you to fit optics with a full size RMR footprint. You would only be able to fit optics with the Shield RMSc footprint such as the Sig Romeo Zero, Romeo Zero Elite, Shield RMSc, Crimson Trace CTS-1500, Vortex Defender and more. If you have an optic ready XD-M Elite, you will need to use the ZD-M OSP Trijicon RMR optic plate which can be found by using the link below:
