Rear Sight Dovetail Mount Compatible with Glock Holosun 407K 507K,Osight K/S/SE,Romeo Zero,Shield RMS

It was perfect fit on my Glock 43 x. I used a sight pusher to install and it had no problem sliding on. It came with plenty of screws and the tools to tighten them. Now I just need to buy a red dot to mount to it.

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

This is a great product. Fits great on my Glock 43x. The instructions say to shave or file the dove tail down if you don't have a sight pusher. Please don't do this. Just get a sight pusher. You run the risk of it not being straight or completely tight or coming loose. Just get the tool or have someone do it for you. Otherwise this is great quality and I'll buy a couple more. It fits my Holoson 507k nice and solid and have no problem racking the slide with the sight for emergency training and such. The Pic provided was with the sig romeo zero. Fits fine with that but that sight is trash.

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

Works and fits perfectly

This dovetail mount is well made, quality of materials is excellent. Installed very easy on a Glock model 22. Romeo Zero mounted just fine and zeroed just like its suppose to. Put 300 rounds initially when I mounted it, held zero, steady as a rock. Back at range a second time put 600 rounds on it and steady as a rock and no shift in zero. I was going to have the slide milled, but someone told me about this mount and recommended I try it first. It was definitely with the money and considering I'm completely satisfied with it and no longer need the slide milled this mount has even saved me money.

Ordered and for some reason received a damaged used one but i was taken care right away and they replaced with a perfect one, it does fits perfect and very sturdy, cant wait to shoot with it and zero in the sight great quality for sure very recommend.

Update 03/05/2021 I finally took it to the range and zero it. It was really easy to zero since the factory setting was already centered and the plate is actually slightly tilted so it can co-witness with the original sight at the distance around 15 yd. Although I did mentioned that the plate is not touching the slide surface after pushed into the dovetail, see the second last picture, but once all the screws are in, the plate is actually tilted so the front edge does touch the slide now. That helps when elevation adjust can't crank more than 30 MOAs in some red dots. During the zeroing and later shoot (around 200 rounds), the red dot is mounted very sturdily, so I couldn't find any shift at the end. More shooting reports will follow if something does go wrong. ---- It took me some courage to order this item, since there are only two ratings, one at 4 and another was 5, but no review, no pictures. Nevertheless, I decided to give a try, at worst, that’s only $20. First is the the setting, I have a Glock 45 with regular slide, no MOS. The factory sight is simply getting hard for eyes, especially in the dark. I was debating between a Truglo night sights (much cheaper) and this a red dot sight. The problem with later is that you have to get your slide milled so a red dot can be installed. Nowadays, it may take up to months to do so. Then I saw some youtubers are talking about the mounting a red dot on the rear sight dovetail. Just when searching, most of the solutions are quite expensive and some have to wait for back order. Then I find this little item on Amazon. It just had everything I’m looking for, yet no reviews. Nevertheless, after getting this plate and my Holosun 507K, I trial fitted both and they just works great with each other. Then I pushed off the rear sight and put The plate into the dovetail, with some initial hammering and then a slide push tool, it fit in tightly. Notice that the plate and its dove tail are in one single piece, however the bottom of plate is actually not touching the slide, so no worry it will leave any scratch marks, yet still very sturdy and tight. I haven’t zeroed the red dot yet, and not sure if it will stay tightly snuggled after several hundred rounds of firing. I will report that later.
