DPP Titanium Rear Sight Dovetail Mount/Mounting Plate/Adapter Compatible with Glock Holosun 507K,Shield RMS

This item works well as it sits evenly on my Glock 26 (gen 4) and holds my Sig Romero Zero nicely. Know that this will fit this footprint and not the larger Red Dots. I have a couple laying around and want to utilize them. Unfortunately, my Romeo does not adjust enough...not just for this adapter, but in general...so don't get one of these, get an Ade Spike instead. Because of the lack of adjustment, I had to file away material from the back end where the optics sit to angle it up. You can't even see or tell it was manipulated in anyway because it only needed a .01inch of material sanded off and that is the most removed as it was a gradual decent towards the back. Anyway, both will fit perfectly on the Glock frame.The adapter itself is great! It sits with only .001 inches of gap between it and the slide. That's nitpicking. Your mileage may also vary, however, I will never see that again aside from install or removal. The frame is just a tad bigger than my Romeo, but looks great! I do like it better than the RMR types, especially on my 26 as the size of the ultra micro optics fit within the frame and it does not bulk out. It comes with the adapter, three sets of screws to fit its suggested optics, three frame screws (two are extras).DYI'ers...Do read the paper that comes with it. You can file the area that sits in the iron sight if you do not have a puller or a way to slide the adapter into place. This helps a lot with installation. A punch and hammer will get you there, but it takes a heck of a lot more time to center, so just file that area down.The screw that comes with it will lock it into place.

As described. A bit too wide for the GLOCK 43X but fits the Holodun 507K perfectlyCame with a variety of screws, all with loc-tite on the threads

Make sure you know which direction to remove your rear sight. It does make a difference. Sand the black coating off of the bottom of the dovetail part of this optic plate. It should be bare metal. Use a very thin film of gun oil or similar and a rubber hammer to tap the slide plate in place. Center as well as possible. Buy a torque wrench and torque the plate screw and 2 optic screws to 18lbs

Not compatible with Canik TP9 SA. Dove tail is much narrower than original sights. FYI- Product is not very thin and doesn’t curve with the slide

I got this plate to adapt a stock, non-milled, Gen 4, G23 slide to a Vortex Defender CCW red dot.The hardest part of installation was removing the rear dovetail sight. Once that was out of the way, installation was straightforward and the fitment and finish is excellent. Everything holds snug and the sight is not obtrusive in any way. Highly recommended for this combo.

I have been a Gunsmith for 44 years so I feel confident in my review. I mounted this plate on a Glock 27, a .40 caliber pistol. Though not needing to do so I read the instructions and they were quite concise and would serve the untrained user very well. Upon mounting and centering the plate with the slide it was torqued and the an Sig Tango Zero was attached to the plate. All holes aligned perfectly and the unit mounted easily.Range testing was quite impressive as the unit remained Rock Solid after 50 rounds of fire. From what I can assess this mounting system is well worth the money. One last point was the inclusion of 3 different lengths of mounting screws that were all pretreated with blue locktite, indeed a sign of quality from this company.Be SAFE…..Shoot Well

I purchased this optic mount to enable installation of a Holosun 507k K2 on my Taurus G3C pistol. My sole doubt was the one piece design, not enabling me to change plates at a later date, without removing the dovetail insert. All is well, the dovetail fits perfectly, tight, and has a screw to lock into position once centered. My large impression was the packaging; a nice hinged plastic container with every screw any person could require for all mountings, different lengths, different head diameter and bit types, all with Loctite . The Holosun unit seems quite secure and is tightly fixed to the mount with 2 screws. Price is fair.

I bought this plate to try and optic out. I did about 2000 rounds and only took the plate off because I decided to get my slide milled. The Holosun optic I had sat well and I saw no signs of wear. Make sure you follow installation instructions and use the proper materials.
