Adapter Plate for Glock 17 19 MOS Holosun 407/507C/508T 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.

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.

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!

Great fit with my Glock 17 Gen 5 MOS. Easy to install with the Holosun 507C GR. Had all the required screws. Recommended.

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.
