DPP TitaniumRear Sight Dovetail Mount Compatible with Glock Non MOS Vortex Venom & Viper, Burris Fastfire, Docter

I originally planned on returning this item because I was having trouble getting in on my gun. It was so tight fitting that I was afraid that I might damage it or the slide while trying to install it. I tried putting it on my Glock 26, 32 and 34. All had the same issue. It would go in about 1/3 of the way and then it didn’t want to go any further. I watched a YouTube video and read several reviews and all said that you had to beat it in pretty hard to get it to seat. I wrapped the slide up really good and put a small wooden block on the side of the mount and used a heavy hammer to beat it in. And I mean beat it in. It took several hard whacks to finally get it all of the way in. I even put a drop of oil in the dovetail channel before I started thinking that it might help. It centered up well and I mounted a Crimson Trace cts-1300 on it. I shot 34 rounds through it and it held tight. I can bet that it ain’t going anywhere. My only concern is if I ever want to take it off, how hard will that be? It is too wide to use a traditional sight pusher so I guess I will have to use a copper punch and hammer.The kit comes with all of the mounting screws that will fit several different sights. The Burris screws tightened my Crimson Trace down just right. Screws already have blue Locktite on them. I went ahead and ordered another one that will accommodate the rmr/ Holosun type since I think that I want to put one of them on another Glock. This is the best option if your gun is not MOS ready and you don’t want to spend $150 to get your slide milled. The sight does sit a little higher than if you did have it milled but the ability to go from gun to gun, if you wanted to, makes this mount an economical choice. I am happy with it so far.

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.

Fits perfectly on my gen 2 fmk pistol now I just have to find the right sight for that fit the plate

Packaging comes complete with plastic case to store different mounting screws which is awesome. All in all this feels like a quality product. It was easy to install with my cheap Amazon sight pusher. I had some reservations about it staying in place but the set screws resolve that concern, some people reported a minor gap between the plate and the slide, I did not have that issue with my 19x as it fit perfectly and feels sturdy. It isn’t as obtrusive as most dovetail mounts I’ve seen and has a relatively low profile. Only way to get lower would be to purchase the MOS or have your slide milled. I’m not about to do that to the nPVD finish. I have not received my vortex viper optic yet as the plate shipped much faster so I can’t attest to the fitment but the footprint looks correct. I’d say that compared to the $100+ Trijicon dovetail mount you’re not sacrificing quality with this component. Excited to put rounds down range. Remember to clear your firearm before installation and stay safe, everyone!

So with various optic plates on the market, this one worked perfectly as long as you have the right tools. the issue you will encounter is the optic screw lengths and it is determined by the price you get. i had to shave the bolts that work for my optic to ensure a good fit without compromised the plate or the security of the optic.i recommend this product confidently for the fit and function!
