Great way to add an optic to an older pistol
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.

Fits well on Gen 5 Glock 19x with my defender-ccw
Only gone through about 150 rounds so far so it’s a little early to tell but seems pretty legit nothing to really complain about everything fit correctly it held zero and hasn’t moved since. For reference I put mine on my Gen 5 Glock 19x

Read the instructions Dip💩
It works fine if you know your footprint and you follow the instructions. It WILL loosen and move side to side IF you take shortcuts and don't use the expanding lugs. Unfortunately, you don't need a brain to leave bad reviews for a perfectly fine product. In fact, it helps, if you don't.

Plate thickness may not accommodate RDS (Vortex Defender) ability to adjust to sight in dot.
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.

Did not hold up to high heat and recoil
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

Good start or compromise
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.
