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.

Great fit, easy to install, great thread engagement, they even give you extra screws.

Fits perfectly on G17 Gen 3 MOS slide. Mounted a Trijicon RMR red dot on it. Tight tolerances, great fit, very well made! Definitely worth the price.

Bought this plate to mount a Holosun 507C to a Glock 34, Gen 5. Machine work was excellent, and the plate fit perfectly. Came with all the necessary hardware and mounted with no issues. Have not shot with it yet, but I anticipate no problems. Would recommend this plate and purchase again!

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.

I was very skeptical of this optic adapter plate, to say the least. Usually, I'm spending double the price of this product. When my C&H Precision plate failed, the reviews pointed me to this for a try. All included parts seemed to be good quality. The plate itself was nicely machined. My dry fitting of the pistol, optic, and plate absolutely blew me away! All three components WITHOUT screws fit together perfectly and I could tip everything upside down and it all held together. Simply amazing for this price point. My last concern was rested when the screws torqued to spec and nothing broke. My optic was only three clicks left of previous zero, so that tells me it's a winner. I had two more plates in my cart just waiting to see how this one went and I couldn't be happier. I hope I'll never need DDP customer service but they couldn't be any worse than C&H Precision. They are terrible to deal with. Buy DDP! Edit: I did buy another Glock plate and it wasn't quite as tight fitting as the first one. There was a super tiny bit of play between the slide and plate and a tiny bit more play between the plate and optic. Far, far less slop than C&H, so no complaints. I'm happy.

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.

Fit perfect gen 5 glock19. Came with correct screws and was a tight/clean fit.
