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.

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

breeze to install, smithing hammer and block. Had dot installed in minutes

This does mot fit a vortex red dot. Differ footprint on the mount. Waist of time and money to even return.

smart idea but it puts the red or green dot a little high, works good and inexpensive

No need to screw

Comes with no instructions, but not really needed. Brownells has a tutorial how to install a sight without special tools, i.e. sight pushers. Very tight fit to the Glock Gen 2 factory dovetail. Comes with all the needed fasteners for the mount & probably all red dots. You will need to provide your own blue thread locker. The Olight Osight SE fit perfectly.
