I was a little worried that being a this price point would mean a lesser-quality product, but this thing is awesome. It fits very well into my MOS cut 19.5 and mounts an EPS Carry perfectly. Getting titanium durability at this price is awesome. It should be significantly more durable than its aluminum counterparts. Works very well, seems to be very well designed, and is nice and thin meaning your optic can sit nice and low. 100% recommend.

I've run quality brands like CH, Calculated, Forwards and others and DPP works great for the price. I've never had fitment issues or anything coming loose or breaking. Use your thread locker, torque, witness marks and you won't have issues. Thousands of rounds through the pews I have them on with no problems.

If you use a proper torque wrench or at least understand that the screws that attach the plate and whatever optic you choose are SMALL and do not require much torque. You will not break the screws. I used a BW Casey Inch-pound torque driver and did not have an issue. If you do any optics mounting, this is a must for your tool kit. Buy one, they're not that expensive. Then you can stop giving 1 star reviews for cheap metal when in fact you over-torqued the screws. This adaptor plate fit like a glove on my Glock 19 Gen 5 MOS. Very high quality. Screws come with loctite already applied and it comes with extra screws.

The DPP Titanium Adapter Plate is an essential upgrade for Glock 19X MOS owners aiming to mount a Holosun EPS optic. Crafted from aerospace-grade 6AL4V titanium, this plate offers exceptional durability while maintaining a lightweight profile. Its precision CNC machining ensures a flush fit with the slide, providing a sleek, low-profile appearance that complements the firearm's aesthetics. Designed specifically for Glock MOS models, the adapter plate features lengthened posts to maximize thread engagement, enhancing stability and maintaining zero even under heavy recoil. The included high-strength alloy steel Torx head screws come with pre-applied thread locker, simplifying installation and ensuring a secure mount.

Excellent fit on Glock 20 gen 5 MOS to allow installation of Holosun EPS Red Dot sight. A little narrower than the Glock 20 slide (as stated by manufacturer) but hardly noticeable. This plate enables co-witnessing with the standard OEM Glock sights. Good value compared to similar adapter plates on the market. Great job DPP!!!

Ok, so I was pretty happy with the speed of delivery, the included tools and the way it was packaged. The design seems strong and efficient and the product itself seemed of sufficient quality. The plate did not immediately mount on my g19 MOS slide, was too tight and initially I used a rubber mallet to place it. Initially it looked great. But after I mounted my Holosun eps to it, it was also VERY tight. It was all bolted down to listed torque specs and all was good. Then I started to notice the front of the sight had space between the plate and sight I could see daylight through. I adjusted it several times and couldn’t make it work. Then I had to use fine sandpaper to remove the paint from the front and back of the plate to make it fit correctly invthe MOS cutout. This also had to be done on top of the plate for the sight to mount without binding. It was the binding that seemed to be causing the sight to raise on the front. It’s ok now after I fitted it myself but I wouldn’t do this again and if this holds to 1000 rds I’ll be very surprised. I would find another solution before I tried this plate again. A direct mount would be ideal but until Glock starts using a better sight mounting pattern a custom cut is the obvious choice. ****UPDATE:Ok, so I’ve had this for a few weeks. Once I took off the smallest amount of paint on the leading edge of the plate it did fit perfectly. I’ve put around 500 rounds through the gun and it is not loosening up, which is good. The DPP customer service dept reached out to me and wow, how nice to deal with they were. They wanted to refund my purchase and/or send me another at no cost. I said ok and it arrived within days. I haven’t installed it though as my sight is perfectly mounted and dialed in…just can’t bring myself to dismount it just to install an identical plate. I am very happy with this purchase and do recommend it for Glock MOS applications. Of course direct mount is ideal, but this is working really well after proper fitting. DPP is focused on customer service and I appreciate that these days.

I've installed this on my Glock 23 by removing the rear site. While special tools are required to remove and install the dovetail mounts, this saved me a ton of money not having to replace the slide to get an MOS mount. Great product.

Fits very nice. As long as it goes through quality control, you will get a decent plate.
