DPP Titanium Adapter Plate Compatible with Glock Gen 3 to Gen 5 17 19 MOS Holosun 407K/507K/EPS Carry/EPS/Romeo Zero

The plate fit tightly in an G45 MOS slide. I appreciate that the plate came with various optic screws, in labeled bags for different optics. This is super helpful. With this plate I was able to mount and zero a holosun 507k with no issues. Had difficulty zeroing an eps carry. Plate is high quality and came with proper screws so I’m still giving it 5 stars.

Fits Holosun K series, however it does not fit every “Shield RMSc” footprint optic. I was fortunate to be able to get multiple optics for the holidays to upgrade my pistols. I was a little bummed that the new Vortex Defender series utilized a smaller screw hole than the Holosun, so they will not fit over the DPP mounting posts (no fault of theirs). The fit was tight with the EPS and K optics from Holosun over the post and into the plate. The plate also fit well into the MOS slot. Despite the K series being well regarded to run with factor Glock sights, using this plate with the MOS system still means you need taller sights for cowitness. I ended up mounting the EPS to my Gen5 19MOS and was able to get 1/4 cowitness (part of the dots obstructed) with TruGlo low sights (the one with the set screw in the rear sight). The plate comes well packaged, with three sets of screws — two pairs for the mounting plate, two pairs for the EPS optics, and two pairs for the K optics. I like that they include a backup pair of screws in case you mess them up or lose them. Comes with the torx T-10 tool and a nice plastic case I have two of DPP’s RMR plates and they are working fine. I suspect this will also work just as well. For $40 this is a good deal in comparison to premium pricing by their competitors, and much better than the OEM plates that are included (K plate it not included in the MOS series).

Fits like a glove. Well machined & precise with a fine level of finish. Packaged w/ necessary screws & helpful information. Attractively priced. Thinner than other options. When test fitting on my Glock MOS cut, without screws, I could turn the gun and optic sideways and nothing fell off. It was like it was hand fitted. Additionally, because this plate is thinner than others, and the deck of the HS507K is low, you can still see the tops of the factory sights. I definitely recommend this plate.

Quality of the adapter plate seems solid and it fits the Holosun EPS like a glove. Unfortunately I could not verify via the product page if this was compatible with the Glock Gen 6 slide...It is not compatible, so beware.

The DPP Titanium Adapter Plate is an essential upgrade for Glock 19X MOS owners aiming to mount a Holosun EPS optic. Crafted from aerospace-grade 6AL4V titanium, this plate offers exceptional durability while maintaining a lightweight profile. Its precision CNC machining ensures a flush fit with the slide, providing a sleek, low-profile appearance that complements the firearm's aesthetics. Designed specifically for Glock MOS models, the adapter plate features lengthened posts to maximize thread engagement, enhancing stability and maintaining zero even under heavy recoil. The included high-strength alloy steel Torx head screws come with pre-applied thread locker, simplifying installation and ensuring a secure mount.

This is not a direct plug and play. I had to sand and file both front and rear edges to get the plate to fit a G19 MOS. Once I veis that and got it to fit properly, without binding, everything was great. The price is very reasonable so for me it was worth the time to file it down for fit.

This plate is thin. I was able to use the EPS full-size and still co-witnessed with the OEM iron sight on my Glock 17L. It’s more like 1/4 co witness which I like. Putting on the correct torque and it doesn’t seem to loosen but I only got 100 rounds through it so take that with a grain of salt. It also looks good because it fill in the gaps in front and back of the optic. The price is also right.

Installation was fairly straight forward. 407K has held zero on my G19 for the past ~1k rounds and being carried appendix every day. The fit is precise, so I'm quite confident that there will be no significant shift to the zero due to the plate.

Produkt passt perfekt. Aufgrund von Lieferproblemen war der Verkäufer kulant. Vielen Dank dafür!
