Yes, the SIG SAUER X-Ray3 Pistol Sight Set will be compatible with a P320 M17 pistol.
These are the factory OEM sights for the P365.
They will fit the dovetail however you will want to verify your sight numbers, my P320 compact came with a #6 front and a #8 rear sight.
Yes, these sights will fit a P226 and the #8 front and rear are normally meant for a 9mm Sig P-series pistol.
Yes, this should fit.
Yes they will fit the dovetail, however to make sure you are not changing point of aim/point of impact you may want to verify the factory sights were a #8 front and #8 rear height.
No, these will not fit the X-Carry as the rear sights on that gun are attached to the optic cover plate, rather than in the standard dovetail cut. The front sight is compatible but not the rear.
Yes, the product is compatible with the P225 in 9mm.
All P series and SP models use the same dovetail mounting front and rear with the exception of the P250 which has a different rear sight mount configuration (same front sight as others).
However, different Sig Sauer models and calibers come with different sight heights to achieve proper point of impact at 25', depending on the caliber.
9mm and .357 SIG use #8 REAR / #8 FRONT
40 S&W and .45 ACP use #8 REAR / #6 FRONT

Updated Answer: These will technically fit on a P220, but they are not the recommended #'s or heights. Sig Sauer recommends a #6/#8 for the P220 in .40S&W/.45ACP. Trijicon offers a night sight set for the Sig220 here: https://www.opticsplanet.com/trijicon-sg03-3-dot-night-sight-set-for-sig-p220-p229.html
