PICATINNY RAIL Mounting Plate for Glock 17 19 22 23 26 27 34,Taurus GX4,G3C,Canik TP9SA,with built-in screw hole for Shield RMS/Holosun 407k/507k Footprint - ALSO COMPATIBLE with Any PICATINNY RAIL EQUIPPED red dots such as Trijicon RMR,Vortex Venom

Went on easily by using my vice. However they weren't kidding when they said "Don't over tighten". This thing can and will bend. Also, I recommend some thread locker. If you don't use it this thing can and will come loose. Overall though, it fit my Taurus G3 perfectly and allowed me to mount my red dot without issues.

This is a very handy and useful set up. It’s made very well and precise. It mounts super easy and snug. This is a great price for what you get. The coating looks really good as well.

Well this seems to be the best option over buying a new slide or having your existing slide machined to accept a red dot. As stated by another reviewer it sits higher than if your slide was machined but that’s the nature of the beast, tradeoffs. Obviously, the ability to secure the rail with zero movement is critical to keep proper zero on the sight in. This device seems to get the job done. A cheap alternative overall to expensive machining. Works on Glocks.

Got this to add an optic to my 19. It was easy to install and holds tight without any movement. My biggest issue is that it isn't sitting perfectly flush with the top of the slide. I don't get any movement but the chance is there and I'm sure it is going to collect dirt and dust more than it would if it was flush. I plan on pulling it off and doing a bit of machining to see if I can get a flush fit.

A 'dovetail mount' is the easiest and cheapest way to mount an RMR on a non-rmr equipped slide. This mount takes that a step further, adding a picitinny rail, so your choice of optics is increased. To top it off, it also addresses the main shortcoming of those dovetail mounts, namely, the inability to use the sights when the RMR is not present. To combat this, the mount has a machined slot right through the middle, that will stand in for a rear sight. Great improvement on a fairly standard idea.

I like the red dot on my G19 so much I wanted to add to my Gen 4 Glock 26. The installation using a sight pusher is normal and secure but mounting direct to dovetail is too flimsy to keep zero and while the picatinny rail is nice and universal- it also adds height and bulk. Maybe not big deal on larger frame pistol - but on the 26 it was too much for me. None of this is fault of vendor and the mount is exactly what it says - just not good for me.

The listing does warn not to try this if your weapon slide is already modified, so keep that in mind. First, it does seem to be made of good materials. Nothing to complain about there. It's not hard to put on if you're familiar with your weapon at all. There isn't much holding the red dot in place, which is what concerned me. Overall, it came as described, was easy to install, and worked as intended. I'm holding a star because it's average, not stellar, and I'm concerned with the red dot holding zero. I want to use it on the range a few more times to really put it to the test. If it comes out perfect, I'll edit and let you know. For now, it's about average and I would recommend it to a friend, but I wouldn't chase down my friends to tell them to buy it.

The plate that goes into the rear sight dove tail slides right in. However I noticed that when tightening it down, it seems like it's a little small, like there ends up not being a lot of material to hold the plate in the dovetail. In the end I am still able to get a solid lock and the picatinny rail does not move, although it does angle up a little bit. The option to mount an rmr or rmsc is good. The screws on this and optics are generally pretty small and can get over torqued easily. I use loctite and tighten to about 14 in/lbs. This works on my other dots and is holding up on this plate so far for about 250 rounds.

Just a note before my review . The listing for this leads you to believe it is silver colored . It is not, it is actually black. Now on to the review. This is meant to replace the rear sight on a Glock pistol. You need to use a sight pusher to push the rear sight out of its dovetail and replace it with the small dovetail shaped insert. Then you can use the supplied screws to attach the mount to the insert. As you can see in the picture, between the man screws there are two smaller set screws. These are to tighten down against the slide to add more stability. It seems very stable, and the picatinny rail seems to be attached firmly. I would definitely add lock tight to all of these screws. Now that you have a picatinny rail firmly attached to your Glock slide you can now add your red dot. Many red dots come with a picatinny plate attached to the bottom of them. The listing points out that this plate also has built in screw holes that line up with the RMS/ RMSc footprint. In my opinion that is not a good option because there are no indexing posts coming up from the plate to go into the holes in the red dot. This means that you are depending on just the two screws to hold the red dot properly in place. In my opinion, this is just asking for trouble. I think the better option is to use the picatinny plate that came with the red dot. If the red dot did not come with one, and you don't want to get one then I think you should get one of the non picatinny red dot mounting plates that attach to the Glock slide the same as this one. They are available and would have the necessary posts to hold your red dot securely. They would also give you a slightly lower profile for your red dot than this one. This plate is well made and well finished and if you want to add a picatinny rail to your Glock I can recommend this one.

Good fit and easy install. Haven't mounted optic yet but it feels like it will be very solid.

The fit was good and installation was a snap, a good mount for the money.

Easy to mount, mounted it on my G17. It doesn't fit flush. The Quality is good and it's sturdy. It also a good price. Got it in 2 days
