DPP Titanium Adapter Plate Compatible with Glock 17/19 Gen 3-5 MOS Holosun 407/507C/508T/Osight C/XR and Trijicon RMR/SRO

Let me start off by saying if I could give this 10 stars, I would. This plate is 100x better than the factory plate that Glock provides. This plate was suggested in a few of my Glock forums due to a serious flaw with the factory plate and I'm glad I bought it. Came packaged in a small plastic container and everything was labeled. Very nice touch, kudos! This thing fit like a glove, absolutely great tolerances and no issues. The Holosun mounted right up and also fit perfectly. The screws have blue thread locker and it comes with its own wrench. I mounted this on my model 20 10mm and I will see how it holds up after long term usage. I can't say how extremely please I am with this plate so far.

First off I want to start by saying that I bought this plate to replace my RMR plate on my airsoft Glock 17 Gen 5. I know this plate is made for the real gun, but I gave it a shot anyway. Unfortunately it doesn't fit the airsoft version, though with a little bit of sanding and filing it would fall into place pretty easily, the issue is that the nozzle return spring sits under the optics plate and the Dpp plate leaves a slight gap so that spring can come out. Luckily for me I do have a real Glock and it fits perfectly and my rmr fits nice and snug no problem!

Excellent fit & finish. Great quality & value

This is the best RMR plate that I have tested for the Glock MOS system. The plate is extremely well-made with exact tolerances. The nice thing about this plate design is that it has both the front recoil/indexing lugs AND screw posts, which relieves a lot of stress from the mounting screws, lowering the chance of screws snapping over prolonged use. This is the best design for all RMR-footprint optics, except for the Trijicon RCR. -Compared to the OEM Glock RMR plate, the DPP Titanium plate is both stronger and fits the MOS cut a lot better/more securely than the OEM Glock MOS plate that is made of low-quality steel and does not have screw posts. -Compared to the popular Forward Controls Design steel RMR plate, the DPP plate is lower profile while also sitting the optic slightly further back away from the ejection port, which makes a difference for optics with overhang such as the Trijicon SRO or RMR HD. This leaves the optics cleaner and having a lower height-to-bore. The FCD plate also does not have screw posts. -Compared to C&H Precision RMR plates, the DPP plate is a lot more exact in tolerances, meaning the plate fits to the slide more securely. The screw posts also are integral to the plate, which is a better/stronger design.

Using on all firearms works well

Tremendously tight fit. Just about air tight before screws even go on. Outrageous quality for very cheap. WILL buy again.

The plate fits my new G17L.5 perfectly (nice and snug with no wiggle room). Machining and finish are perfect too. My only "complaint" is that although DPP provides screws for Holosun and Trijicon sights, I have an Ameriglo Haven (which uses the same footprint). The Trijicon screws are usable, but should be ~2mm longer to more fully engage the mounting pins that project up into the sight's screw holes. Fortunately, since the sight fits securely onto the plate and there are four mounting pins that anchor the sight to the plate (along with the sight's contact with the front of the plate and the rear abutment of the slide), recoil shearing forces (mostly horizontal) are not fully against the screws; these screws mostly work against vertical forces which are smaller, so even though the screws could be longer they will probably be OK with Loctite compound. Likewise since the plate fits tightly onto the slide, the shearing forces are also handled by the plate's abutment against the slide cutout ends, so the screws that hold the plate at least have the end connections to help secure the whole assembly. I'm pretty confident that Loctite on all screws with proper torquing will assure reliable performance. The plate sure is a very nice piece and it's a big step up from the Glock OEM plate. Personally I can't see how there could be a better plate out there compared to the DPP. Only time will prove whether the screws are adequate of course.

Idk what the issue is with the factory MOS system, but I damaged the screws that came with my glock plate in the box, while using the tool it came with. I replaced those screws and then the screws that came with my red dot would not engage with the plate, nor would any of the other screws that came with the glock plate. I got this and in 10 minutes everything was set up securely with no issues or difficulty. It is a little wider than the factory plate, which I assume allows more of the optic to be in contact with the plate, which I think would make it more secure. Plus there are posts for the screws that connect the optic to the plate, allowing for more tread engagement than the factory plate so they're probably less likely to shear with a lot of use. Overall, these are absolutely superior to the factory glock plates, which leave a lot to be desired unfortunately.
