Trijicon Dual Defense Kits

Trijicon Dual Defense Kits for SIG M17/M18

A Trijicon Dual Defense kit pairs an adjustable LED RMR Type 2 with an M17/M18 mounting plate and optic-height backup sights. You get a 3.25 MOA red dot and a matched iron-sight option in one package. Choose black or Flat Dark Earth, then decide whether you want plain non-tritium irons or Bright & Tough tritium night sights.

Choose Your Backup Sights

Non-Tritium Iron Sights

Non-tritium sights provide a plain, blacked-out reference through the RMR window. They do not glow in low light. Choose these kits if you prefer plain backup sights alongside an illuminated red dot.

• Black with non-tritium iron sights: RM06-C-700817.
• Flat Dark Earth with non-tritium iron sights: RM06-C-700815.

Bright & Tough Tritium Night Sights

The night-sight kits add tritium illumination to the backup irons. Those lamps work independently of the optic battery, providing a separate low-light reference. The black outlines keep the daytime sight picture understated, while the sights remain tall enough to be viewed through the RMR.

• Black with tritium night sights: RM06-C-700818.
• Flat Dark Earth with tritium night sights: RM06-C-700816.

The Same 3.25 MOA RMR in Every Kit

All four configurations use an adjustable LED RMR Type 2 with a 3.25 MOA red dot. Choosing FDE changes the housing color, not the reticle. Choosing tritium changes the backup sights, not the way the RMR’s LED is powered.

The optic offers automatic brightness and eight manual levels, including two night-vision settings. Button Lock-Out helps prevent accidental changes while automatic mode is active. A bottom-loading CR2032 powers the red dot, so battery replacement requires removing the optic from its mount.

What Is Included, and Which M17/M18 Does It Fit?

Each kit includes the RMR optic, M17/M18 mounting plate, optic-height sight set, battery, sealing plate, and mounting hardware. These configurations are intended for compatible commercial M17/M18 pistols. Confirm the exact slide and sight arrangement; a different P320 or military-contract configuration should not be assumed to use the same plate. Professional installation is recommended.

Trijicon Dual Defense Frequently Asked Questions

Does a Dual Defense kit include the red dot?

Yes. These kits include a 3.25 MOA adjustable LED RMR Type 2, not just a plate and iron sights.

Do all four kits include tritium night sights?

No. RM06-C-700816 and RM06-C-700818 include tritium night sights. RM06-C-700815 and RM06-C-700817 include non-tritium iron sights.

Does tritium power the RMR red dot?

No. The RMR uses a CR2032 battery. Tritium illuminates the backup iron sights in the night-sight versions.

Will these kits fit every SIG P320?

No. They are intended for the compatible commercial M17/M18 mounting configuration. Match the kit to your exact slide and sight arrangement before purchase.
