DPP Titanium Rear Sight Dovetail Mount Compatible with Glock Holosun 407K 507K,Osight K/S/SE,Romeo Zero,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.

Easy to install and fits perfectly. It holds the Red Dot Optics firmly.

I mounted this on a G42. It's slightly wider than the G42's frame, but it's exactly the same size as the Holosun 407K I put on it. Installation was really easy, especially if you have a sight pusher tool. I recommend getting a small torque wrench driver and some Loctite Blue for this installation though.

Titanium. Doubtful, if so…. Meh quality titanium. But, it’s sturdy. Nicely made. And it works well. If you can’t figure out how to mount it…. Yer not bright enough to own a firearm, Seriously. Sell it. Moron. The mounting screws are in fact garbage. Get some decent screws. And I removed a star for that. And one for the questionable titanium. Ok. Bye

I was never a fan of dovetails (because the internet said not to be). But I wanted an rmr on my 19x without milling it or spending hundreds on a new slide. I must say, I’m very happy with my choice. It feels super durable, I torture tested it today and it didn’t slide, break, crack, or come off. Relatively easy to install, I used a sight remover so perhaps that’s why. Very slim and fits perfectly. I definitely recommend giving it a shot

Great Mount and fit my Glock 19 gen5 perfectly. BUT what's more important to me is the customer service at DPP. I inadvertently ordered the wrong mount. And reached out to DPP via e-mail.. they provide in the instruction manual. A guy named Henry sent one back in just an hour and helped me. Gave me the amazon link to the proper mount. GREAT customer service.

Quick shipping, pretty easy to install with a sight press. Would be better if it was a little narrower.

Blown away how good this worked on a G17 gen3. Nice fit, no shift in several hundred shots. Worst part is how much you will spend buying more red dots!
