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

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.

Its perfect! 100x better than the Glock plate that seems to warp every time. This product comes with 2 sets of screws for the Glock and 2 sets for each optic type. Quality product and really secures the optic

Fantastic fit

This thing works phenomenally. Ived used it for two different sites and never had an issue. Ran through at least 2000 rounds and has never failed. very durable.

My RMR is not fitting due to the recoil lugs. They are too big and the position may also be slightly out to the optic causing interference. Everything else looks nicely machined and packaged. I am a dimensional inspector.I am going to try the replacement and will update my review based on my findings.Second one fit perfectly!

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.

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.

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.
