Night Fision PLATE+BS RMR/507C SIG P320

The Night Fision PLATE+BS RMR/507C SIG P320 is a purpose-built optic mounting solution for shooters running a red dot on their P320. This is a SIG-specific optic plate paired with Night Fision's signature backup iron sights, designed for pistols cut for the RMR or 507C footprint. Whether you're setting up a duty gun, competition rig, or carry pistol, this combo lets you mount a modern optic while keeping a proven iron sight solution in play—no guessing which aiming system will work when you need it.

The plate itself is machined from 17-4 stainless steel and finished with nitride coating, giving you the durability to handle hard use without rust concerns. At 0.2" thick, it's built to sit solid on the slide. The backup sights are where Night Fision's reputation really shows: their injection-molded sleeve design holds tritium vials secure and creates their "Perfect Dot" ring, which is brighter and more visible in both daylight and low light than the painted-on rings you'll find on most backup sights. That means your irons stay genuinely useful even if your dot goes dark or fails.

Co-witnessing with most optics that share the RMR/507C footprint, this plate-and-sight pairing gives you redundancy without the bulk of large iron sights. It's built for shooters who want their backup sights to actually work, not just exist as insurance they hope never to use.

Frequently Asked Questions

Will this fit my P320 with an RMR or 507C?

Yes, this plate is designed for SIG Sauer P320 Pro Cut models and works with both Trijicon RMR and Holosun 507C optics, as well as other red dots that share the same mounting footprint.

What makes the Night Fision backup sights different?

Night Fision uses an injection-molded sleeve design to hold tritium vials in place and creates a brighter, more durable sight ring called the "Perfect Dot." This design is more visible in daylight and low light than traditional painted-on white rings found on most backup sights.

Will these sights co-witness with my optic?

Yes, the backup sights co-witness with most optics that share the RMR/507C mounting footprint, so your irons and red dot align and work together as one system.

Is the mounting plate durable?

The plate is machined from 17-4 stainless steel and nitride coated, making it corrosion-resistant and built to handle the wear and tear of regular shooting and carry use.
