Yes, the Viridian Weapon Technologies RFX-35 1x22mm Micro Green Dot Sight uses the RMR footprint.
Viridian Weapon Technologies does not specify a specific recoil rating for their RFX-35 1x22mm Micro Green Dot Sight. It should be able to retain zero just fine on a 10mm pistol, although I would recommend contacting Viridian Weapon Technologies directly for confirmation.
No, the Viridian Weapon Technologies RFX-35 uses the Trijicon RMR footprint while the Hellcat Pro will only accept optics with the smaller RMSc footprint. You can fit optics such as the Shield RMSc, Sig Romeo Zero, Vortex Defender, Viridian RFX-15 and more.
The Viridian Weapon Technologies RFX-35 1x22mm Micro 3 MOA Green Dot Sight will fit a Sig P320 XTEN.
To mount the Viridian Weapon Technologies RFX-35 1x22mm Micro 3 MOA Green Dot Sight on a non optics ready M&P 40 you will need the adapter plate at the link below.

The Viridian Weapon Technologies RFX-35 1x22mm Micro 3 MOA Green Dot Sight is not compatible with an MC2SC. The MC2SC fits optics that use the RMSc or K footprint such as the Sig Romeo Zero, Vortex Defender, Holosun EPS Carry, Holosun 407K/507K, Shield RMSc and more.
The Viridian Weapon Technologies RFX-35 1x22mm Micro Green Dot Sight is not compatible with a Glock 43X MOS. This optic uses the Trijicon RMR optic footprint, which is much larger than the RMSc footprint the 43X MOS is designed to accept. I would recommend using the Swampfox Sentinel 1x16mm Ultra Compact Micro Dot Sight, which will mount directly to your slide without the need for adapters or modification and features green illumination options. It can be found by using the link below:

The Viridian Weapon Technologies RFX-35 1x22mm Micro Green Dot Sight houses the battery on the underside of the optic. You must uninstall the optic to replace the battery. An RMR pattern sealing plate can be used to protect the battery housing whilst installed. You can find a compatible sealing plate by using the link below:

Since the Mossberg MC1SC does not come optic ready from the factory, you would need to have your slide milled or use an adapter plate to fit an optic. Unfortunately, we do not carry an adapter plate that would allow you to install an optic to your Mossberg.
The Viridian Weapon Technologies RFX-35 1x22mm Micro Green Dot Sight uses the RMR footprint which is the same as the Holosun 507C.
