Yes, the SIG SAUER OPMOD ROMEOZero includes a steel protective shroud.
The SIG SAUER OPMOD ROMEOZero Reflex Red Dot Sight does not include a picatinny mount to attach to a flattop rail. You must purchase a mount separately. The SIG SAUER Universal Reflex Sight Riser Mount will be compatible with this optic and can be found linked below:

Yes, the SIG SAUER OPMOD ROMEOZero Reflex Red Dot Sight mounts directly to the optic ready slide of the P365X.
The SIG SAUER OPMOD ROMEOZero Reflex Red Dot Sight will mount directly to the P365 Spectre Comp without the need for an adapter plate.
The SIG SAUER OPMOD ROMEOZero uses the RMSc footprint, designed for slim micro-compacts. It can fit a Glock 19 if you have an MOS (optic ready) model if you use plate #4 included with your Glock. If you do not have an optic ready Glock 19, you can use the Evolution Gun Works Leupold DeltaPoint Pro Sight Mount (linked below). However, I would still recommend using a larger optic to get the benefits of a larger window and a better fit. Email us at Techsales@opticsplanet.com for more information.

The SIG SAUER OPMOD ROMEOZero Reflex Red Dot Sight houses its CR1632 battery on the underside of the optic.
The SIG SAUER OPMOD ROMEOZero Reflex Red Dot Sight will directly mount to the optic ready slide of a Hellcat Pro and allow for a lower 1/3 co-witness using the OEM iron sights.
The Sig Romeo Zero uses the smaller RMSc footprint while the P320 X-Compact is designed to accept optics with the Deltapoint Pro footprint. I would recommend the SIG SAUER ROMEOZero Pro, which is basically the scaled-up version of this optic with a bigger window and uses the Deltapoint Pro footprint, which will directly mount to your P320. It can be found by using the link below:

The G3c TORO was designed to accept full size optics, not slim micro-optics like the Romeo Zero. You can fit this optic using the #4 plate included with your pistol, but you may have to cut the screws provided by Taurus. I would recommend using full sized optics with the RMR, Deltapoint Pro, C-More, or Docter footprints. For more information, email us at Techsales@opticsplanet.com.
The SIG SAUER OPMOD ROMEOZero will mount directly to the Hellcat Pro, no adapter plate required.
