DPP Titanium Rear Sight Dovetail Mount Compatible with Glock Non MOS Vortex Viper, Burris Fastfire, Docter

Fit perfect seems high quality enough

A little space between the slide and the mount, but the installation is solid and mounted a Burris fast fire 3 and it is supper tight!

I got this to install a Vortex Viper on my Glock pistol. It came with an assortment of screws and a couple small allen wrenches - everything needed. It's a precision-machined piece; slid into place and fits flush against the top of the slide. There are less expensive alternatives, but I'm happy I went with the DPP. Recommended.

This is my second purchase of red dot mount for my glock 19. The first time I bought a $15 mount but it started to loose after about 50 rounds. I think the design is not strong enough because the dovetail and mount blocks are installed apart. Then I found this one-piece design mount. I look at the description and reviews, all the reviews are very good except one that makes me very confused. That review said this mount sits above the slide. I consulted the seller and they told me that the design could not eliminate the gap between plate and top of the slide, but it could be minimized. All products now have a tighter dovetail design that minimizes the gap. They also told me that if I was worried about the firmness of the mount after the installation, I could use a rubber hammer to hit it casual. If there is any damage or looseness, they will send me a new one. Of course, I will not do this. I am afraid that will be damaged my slide, lol!!! They did a great job on new products, fits very well. It took me about 5 minutes to install, very easy to install. Now hundreds of rounds through it, very sturdy, I am very satisfied.

Well made optics adapter plate for my gen 3 G20. Installed with ease using a rear sight tool. The plate is super solid and provides a seamless mount for my BFF3.

2nd UPDATE: The seller let me know that their latest version fits even better. I will try this sight again. UPDATE: I received a detailed reply from the vendor explaining the trade offs they considered in designing the mount, the testing they have done, some suggestions for how to install it, and they even offered to send me a new mount if I am not satisfied. It seems that due to the titanium’s strength, this mount has been shown to be very sturdy, even with the slight gap. I am upping to 5 stars. Excellent customer service in addition to a well made product deserves that, even if it doesn't fit the way that I had expected it to. I would buy from DPP Titanium again. Original review: The mount is nicely machined and well made in general. The parts are nicely packaged and screws for various optics are sorted in individual labeled baggies. The mount is also lightweight, and it is about as low profile as it can be. The problem, and the reason I returned it, is that the mount sits up above the slide once you tighten down the screws. You can see in the picture I attached that the dovetail protrusion on the mount does not sit flat on the base of the dovetail cut either. Glock dovetails are slightly tapered to be tightest in the center and looser on the left and right side. So from what I see, the mount is only supported by the center portion of the tips of the dovetail, and by the screws which touch down on the bottom of the dovetail. This would be a really awesome mount if the screws actually spread the dovetail protrusion as they are inserted, forcing it into the bottom corners of the cut on the slide. That would pull the mount downward, and support it with more surface area. I was working on a Gen3 LE trade-in 17, with no obvious signs of dovetail wear, but if others are not having this issue I would be curious to find that out. 3 stars for being a good product, with fitment that just didn't meet my expectations.

Broke and flipped back in my face after 2 shots. The aluminum isn't strong enough for firearm applications.

I have a Glock 19 gen 4 non mos. I bought this thinking it would fit my holosun 407 a which is the same size as the 407c. It does not fit.
