Monstrum Dovetail Red Dot Mounting Plate for Glock Pistols | for Non-MOS Version Glock 17 19 20 21 22 23 34 35 40 41 45 47 | Compatible with Holosun RMSc/407k/507k/K Footprint Red Dots

Another great product from Monstrum Tactical. I needed to add a small red dot to an older Glock. This did the job nicely using the dovetail rear sight cut on the slide. This is not one of those flimsy items I keep coming across. This is well made and fits perfectly. (You need a sight pusher to install it. All the hardware and simple tools needed are in the package. (Including mounting screws for the Red Dot itself) I used a CT RAD optic that has an integrated rear sight cut built into it for co-witnessing. Very pleased with the result.

In the past, maybe 5 years back, I was never a fan of Monstrum products. In the past several years I've tried a few more of their products based of 704's YT reviews. Monstrum has come a very long way. This plate is way less expensive than most of the others out there. It was to used on a range only plinker tool. I can't tell you how impressed I was with the quality of the plate and the awesome fit. It worked out perfectly and saved me 50 to 75% compared to the "big name" dove tail mounting plates. It looks great with a really nice finish and it functions very reliably. Use blue loctite and take your time installing it. You'll be really happy with the end result.

Perfect fit in by Glock 45 and my Osight SE fit perfect too. Great solution instead of getting your slide milled.

Appears durable and fit perfectly and sugly but plate is thicker than expected and RDS I wanted to mount, Vortex Defender, doesn’t have enough MOA depression to correctly sight in dot. Likely will have to have my G23 slide cut for RDS which I didn’t want to do and why I decided to try this plate.

Installed on my Glock 19x and went and shot about 200 rounds and the soft aluminum did not handle the heat and recoil of the gun. I would not recommend for a shooter that puts a lot of rounds down range

It works like a glove however you need a special tool to remove rear sight and install plate tool is cheap on eBay

Bought and used on a Gen 5 Glock 19, bought prior to the MOS version release and did not thing future for adding a red dot. This is a good compromise if you don’t want to spend a bunch of money on a new pistol or a new slide or getting your slide cut. This is also a great option if you’re unsure about red dots on pistols, but keep in mind this version a dedicated mount are different. So far I haven’t had issues with loosing zero or it coming loose. In fact during installation it was quite tight and had to be beat to get into place. Don’t be afraid if it doesn’t just slide in with a few simple taps, it’s gonna take some work to get it in but that only further leads to it holding zero and being a solid mount.

Buying used but in good condition saved a few bucks and could not tell it was used, overall very good quality
