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.

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.

Great adaptor. The titanium adaptors may be more durable (I buy them for heavy recoiling pistols) but the aluminum ones work too. Note to self: make sure you’re buying the right adaptor, duh.

Worked ok but didn’t keep level after tightening. Need a good red dot that could set right with offset other than that holds good n works

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

great optic mount very solid stayed zerod

This item worked perfectly to mount a Holosun 407K on my Glock 43X (Non-MOS). This plate mounts the optic directly above the dovetail, rather than further forward. I tried numerous mounting plates before I finally found this one.

I usually can find some sort of fault with a product and I really look hard at this item... none found. I did my research on what adapter plate I needed with what red dot I wanted. I removed the OME sight with a pusher tool. Hammers and guns make for expensive mistakes, I would rather spend the extra money for the right tool. Installation was a snap using a vise and soft jaws, resulting in a snug fit and no marring. The mounting screws came already loctited along with the necessary wrenches. Some sights require their own special screws and direction of the plate dovetail...glock happens to be such for the latter.
