Monstrum Dovetail Red Dot Mounting Plate for Glock Pistols | for Non-MOS Version Glocks | Compatible with Glock 17 19 20 21 22 23 34 35 40 41 45 47 | Compatible with Docter Footprint Red Dots

I use a lot of Monstrum products and haven't been disappointed yet. This high quality adapter plate is perfectly sized to slide into my G19, 17L and 21L with no problems. My 21 is converted to 460 Rowland which produces near 44 mag ballistics and this adapter plate has survived over 500 full-power loads. The sight fit tightly and when snugged down with some Loctite, hasn't moved. Installation is so easy a caveman can do it as long as he has some common sense.

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.

fit on my Taurus gx2 just fine. need longer mounting screws for red dot

Garbage. Don't waste your money.1. first red flag - slid the mount onto the dovetail and it was very sloppy / not even close to fitting tight2. snugged the first optic mounting screw and it was fine / snugged the second mounting screw and the mount stripped out / I hadn't even used my torque driver yet.

Perfect fit and install was smooth.

I was happy with the attention to detail in packaging and the overall appearance of quality.I had to do a slight bit of filing on the dovetail’s anodizing for it to fit nice and tight on my Glock’s slide with just a little light tapping. I did not mind the extra work to get the fitment just right. It makes for a much more secure mount.The problem was after everything was centered perfectly and the set screw was locktighted in place, when I was mounting the RDS to the mount, one of the screws would not start into the mount’s threads because of either too much anodizing or poor machining.So the whole thing had to be uninstalled and the I had to run a tap through the threads.From the amount of shavings, I have to conclude that it was poor machining. Not a deal breaker for me. Sh”t happens and you can’t inspect every single piece that gets manufactured at the price point these mounts are sold for. But, I did want to let anyone that does not have a minimum of mechanical skills to know that they may or may not encounter difficulties and need a hand with installation.Obviously, I can not comment on durability until I run through a couple of qualification sessions with it, and honestly this was only purchased by me to try and see if I wanted to go through the process of milling a slide or two on my pistols and use a RDS permanently.

Went on as advertised, nice tight fit! You will need a sight pusher to remove the night sights that come on most glocks. My red dot went right on it and it holds well. Not bulky or anything like that, fits the footprint perfectly.

Fit ok for manual mounting
