DPP Titanium Adapter Plate Compatible with Glock 17 19 MOS Holosun 407/507C/508T Trijicon RMR/SRO

Extremely tight fitting. I decided on this plate since it sits the RMR HD lower and further back from the ejection port than other plates on the market. Also the screw posts are a plus for the design.Screws come with threadlock reapplied making installation easy.

So far, good solid product and great price compared to others. No issues out of the box. Fit my handgun perfectly and was a super easy install. Holosun 507c fits great, also easy install. Will update in future if any issues arise after some trips to the range.

I ended up picking this up after one of the mounting screws for the factory RMR plate sheared off. The fit is fantastic and the included hardware is good; I'm really glad holosun-specific screws were included. The optic (Holosun 508-T) fit snugly onto the posts, and the gap between the posts and the rear of the cutout is very tight such that there's virtually no possible forward to back movement. It also seems to be ever-so-slightly lower in profile than the factory plate. Well worth the money and a substantial upgrade over the factory plate.

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.

Put this on, torqued the plate and optic down to specs listed in the instructions and ripped off about 500 rounds without issue. The optic is still seated snugly and never lost zero. Cant ask for much more than that. Plate is not too thick and it seems to be a better fit for the 507c than the oem Glock plates.

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've had C&zh precision plates, FCD plates, and glock oem plates. This plate is #1 out of them all. Fits perfect into cutout with no wiggle room! Also has 4 points of metal contact with optic instead of none or 2 with others. Also, this price is half of the expensive others! A+

The first unit I received did not have the holosun screws. The plate also had a defect in the right sight attachment from the milling. The replacement I had worked out perfectly. Installation was quick and so far it seems to fit well. The plate fits my Glock 40 and holosun 407c perfectly and is quite flush with the system. I’d purchase again but make sure it has the proper screws. The screws are all labeled. I’m wondering if the first unit I received was a return as the drill holes didn’t fit well and there was some abrasion on the holes. One star removed for that.
