Yes, the SRO will fit your Prodigy with the correct Springfield Armory adapter plate: https://www.opticsplanet.com/springfield-armory-trijicon-rmr-agency-optic-system-mounting-plate.html
C&H also offers one: https://www.opticsplanet.com/c-h-precision-weapons-agency-optic-system-optic-mounting-plate-trijicon-rmr-holo.html
Both include the rear sight.
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.
A 1 MOA, 2.5 MOA & 5 MOA model is available. You can select the version you'd prefer using the "Reticle" drop-down menu.
A genuine Trijicon SRO is recoil rated for anything you put it on. I would swap the battery with a fresh brand name battery, and if it is securely seated and still happens, you either have a common counterfeit, or return it to the retailer if possible, or Trijicon. This should never happen with any Trijicon product. Some entry level batteries are awful quality, and often a good battery fixes such issues.
