Description
The Forward Controls Design OPF-G, DPP is a billet 4140 steel mounting plate that lets you run a Leupold DeltaPoint Pro on a Glock MOS slide. It's a collaboration between Forward Controls Design and TangoDown, built on the same proven approach as the OPF-G, RMR plate that earned FCD its reputation. Everything is heat treated and finished in black nitride, so you get a tough, corrosion-resistant part that looks right at home on a duty gun or a range blaster.
The whole point of this plate is keeping the optic dead still. The DeltaPoint Pro rides on four recoil lugs and beefier screws than an RMR, but loose and sheared sight-to-plate screws are still the usual failure point on cheaper mounts. FCD tackles that with a front and rear fence that cradle the optic, plus tight plate-to-slide and sight-to-plate tolerances that keep movement along the bore to a minimum. The result is a setup that stays zeroed round after round.
What the OPF-G, DPP Fits
This plate is made for Glock MOS pistols running Set 01 plates, which covers the G17, G19, G20, G21, G22, G23, G26, G34, G40, G45, G47, and G49. The G40 in 10mm uses the wider Set 02 cut, and while the plate still works, it won't completely fill the width of that MOS slot. Because the DeltaPoint Pro footprint is shared across several optics, this plate also accepts the EOTech EFLX and Vortex Defender ST, XT, and XL.
Install and Fitment Notes on the DPP Plate
Torque matters on these. FCD calls for 13 in/lb on the plate-to-slide screws and 25 in/lb on the sight-to-plate screws, and a little thread locker on the included hardware goes a long way. One thing worth knowing: the DeltaPoint Pro sits fairly tall, so if you want a lower 1/3 co-witness you'll need equally tall suppressor-height backup sights. Made in the USA.

Frequently Asked Questions
Which Glock models does the OPF-G, DPP plate fit?
It's built for Glock MOS pistols that use Glock's Set 01 plates, including the G17, G19, G20, G21, G22, G23, G26, G34, G40, G45, G47, and G49. The G40 in 10mm uses the wider Set 02 cut, so while the plate still mounts, it won't completely fill the width of that MOS slot. For most standard MOS slides, it's a direct fit.
Will optics other than the DeltaPoint Pro mount on this plate?
Yes. The plate is cut for the Leupold DeltaPoint Pro footprint, which is shared by several optics, so it also accepts the EOTech EFLX and Vortex Defender ST, XT, and XL. Keep in mind the Vortex Defender and EFLX use different screw lengths than the DeltaPoint Pro, so always confirm your screws seat correctly before final install.
Does this plate keep the optic from coming loose under recoil?
That's exactly what it's designed to do. The OPF-G, DPP uses a front and rear fence along with tight plate-to-slide and sight-to-plate tolerances to hold the optic immobile, which is the simplest way to stop sight-to-plate screws from loosening or shearing. Stick to the specified torque values and use the included thread locker for the best results.
Can I co-witness backup iron sights with the DeltaPoint Pro on this plate?
You can, but the DeltaPoint Pro sits fairly tall, so a lower 1/3 co-witness requires suppressor-height backup sights. Standard-height irons won't line up through the window. Plan your sight setup around that taller deck height if co-witnessing is important to you.
