Daniel Defense H9 RDS Adapter Plate 1 Kit

Product Description

The Daniel Defense H9 RDS Adapter Plate 1 Kit (part 28-196-14269) is the Shield standard footprint plate for the DANIEL H9 pistol, which Daniel Defense also describes as Delta Point Pro and Sig Romeo compatible. It is machined from stainless steel and supplied with all necessary mounting hardware and an installation tool.

Daniel Defense builds the H9 optic ready, with a CNC-machined optics mounting plate on the slide, and sells four numbered adapter plates so the pistol can host almost any current red dot. The plates are not interchangeable: each is cut for a different footprint, and the only thing that decides which you need is the optic you already own. This page is Plate 1.

Optics Daniel Defense lists for Plate 1

Plate 1 covers the Shield standard footprint. Daniel Defense’s RDS manufacturer index assigns these optics to Plate 1:

• EOTech ELFX
• Holosun SCS 320
• Leupold DeltaPoint Pro

If the optic on your bench is a DeltaPoint Pro, this is your plate. If it is not named above, it is far more likely assigned to another plate number than unsupported.

Key Facts

Which of the four plates do you need?

Work from the optic, not the pistol. All four kits fit the same H9 slide and differ only in the footprint machined into the top face:

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

Guessing costs you a plate that will not take your optic’s screw pattern, and a second order. The H9 itself is a compact 9mm with a 4.28 in. barrel, a 15-round magazine and a low bore axis, so a dot suits it well. See our optic plates and adapters and the red dot sights we carry.

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 optic footprint is Daniel Defense H9 Plate 1 cut for?

A: The Shield standard footprint, which Daniel Defense also describes as Delta Point Pro and Sig Romeo compatible. Plate 1 is the plate assigned to the Leupold DeltaPoint Pro, the EOTech ELFX and the Holosun SCS 320 in the RDS manufacturer index for the H9.

Q: Will Plate 1 mount a Leupold DeltaPoint Pro on a DANIEL H9?

A: Yes. The DeltaPoint Pro is one of the three optics Daniel Defense assigns to Plate 1, and the footprint itself is described as Delta Point Pro compatible. The kit includes mounting hardware and an installation tool; use that tool rather than a driver bit.

Q: My red dot is not on the Plate 1 list. Will it fit the H9 at all?

A: Probably, on a different plate. Daniel Defense publishes four H9 plates covering the Shield standard, Trijicon RMR/SRO, C-More standard and Docter/Noblex standard footprints, mapping roughly eighty named optics across them. Call 817-393-4000 with your model number and we will tell you which plate it falls under. Call 817-393-4000 and we will name the plate.

Q: What screws hold the plate to the H9 slide?

A: Two T-15 Torx Plus screws, with the plate’s alignment arrow facing the muzzle. The kit contains all necessary mounting hardware plus an installation tool, and Daniel Defense instructs owners to use that provided tool specifically to prevent stripping the threads in the slide.

Q: What is the plate made of?

A: Stainless steel. It matters on a part that sits between a steel slide and an optic and carries the full reciprocating load every shot, which is a known failure point on optic-mounted pistols. Stainless also copes with sweat and solvent exposure.

Q: Do I need anything else to mount a red dot on my H9?

A: The kit contains the plate, all necessary mounting hardware and an installation tool. Your optic’s own screws come with the optic rather than the plate, and screw length varies by model. Call 817-393-4000 to have your optic’s hardware checked before ordering.
