Daniel Defense H9 RDS Adapter Plate 2 Kit

Product Description

The Daniel Defense H9 RDS Adapter Plate 2 Kit (part 28-196-15266) is the Trijicon RMR / SRO compatible plate for the DANIEL H9 pistol, machined from stainless steel and supplied with all necessary mounting hardware and an installation tool. It carries the largest group of common duty and carry red dots in Daniel Defense’s index for the H9.

The RMR footprint became the de facto standard for pistol optics, and Plate 2 is Daniel Defense’s answer to it on the H9’s factory optics cut. If you own a Holosun 507C, an RMR, or one of the many sights built on that pattern, this is the kit.

Which of the four plates do you need?

All four kits fit the same slide; only the footprint on the top face differs:

• Plate 1 — Shield standard footprint
• Plate 2 — Trijicon RMR / SRO footprint
• Plate 3 — C-More standard footprint
• Plate 4 — Docter / Noblex standard footprint

One caution specific to Plate 2: several makers build optics in both RMR-pattern and other-pattern versions under near-identical model names, and Holosun’s numbering in particular rewards careful reading. Check the exact variant before ordering. See our optic plates and adapters, our red dot sights, and the holsters that suit an optic-equipped H9.

Fitting the plate

The plate fastens to the slide with two T-15 Torx Plus screws, alignment arrow toward the muzzle. The kit contains the mounting plate, all necessary mounting hardware and an installation tool, and Daniel Defense is specific that you should use the provided tool to prevent stripping the threads. The slide is 4340 alloy steel and those threads are small: seat the plate flat, use the supplied tool, leave the power driver alone.

Frequently Asked Questions

Q: Which footprint is Daniel Defense H9 Plate 2?

A: The Trijicon RMR / SRO footprint. Plate 2 is the plate Daniel Defense’s RDS index assigns to the Trijicon RMR and SRO themselves plus the many optics built on that pattern, which is why it fits the largest group of current pistol red dots of the four H9 plates.

Q: Will this plate mount a Holosun 507C on a DANIEL H9?

A: Yes. Daniel Defense assigns the Holosun 507C, 507C V2 and 507C X2 to Plate 2, along with the 407C family and the 508T and 508T X2. Confirm your exact variant first, because Holosun builds optics on more than one footprint under similar numbers.

Q: Does Plate 2 fit the Trijicon SRO as well as the RMR?

A: Yes. Daniel Defense lists both the Trijicon RMR and the Trijicon SRO under Plate 2, which share the same mounting footprint. The SRO’s larger window sits higher than an RMR, so if you run suppressor-height or taller iron sights, check your sight picture after mounting.

Q: My optic is not on the Plate 2 list. What now?

A: It is probably on one of the other three. Daniel Defense publishes four H9 plates covering the Shield standard, Trijicon RMR/SRO, C-More standard and Docter/Noblex standard footprints and maps roughly eighty optics across them. Call 817-393-4000 with the model rather than guessing.

Q: How does the plate attach to the slide?

A: With two T-15 Torx Plus screws, alignment arrow facing the muzzle. The kit contains all necessary mounting hardware and an installation tool, and Daniel Defense instructs owners to use that provided tool to prevent stripping the threads in the slide. Do not substitute a power driver.

Q: Is the plate steel or aluminum?

A: Stainless steel. On an optic-equipped pistol the plate is the load path between a reciprocating slide and the optic, so material and flatness matter there more than saved weight. Stainless also handles the sweat and cleaning solvents a carry pistol is exposed to.
