Great quality optic adapter plate for Glock pistols.
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.

Good but has flaws
Product is solid but included optic screws were too short and the screws that came with my optic were smaller than the mounting holes

Nicely made and fits well
Does work well. Very well made an durable, Holds zero well. And puts together pretty easily with a nice fit and look. However. It does make the red dot sit high. So something to consider. But much cheaper than having a slide cut

Compleat garbage DO NOT BUY!!!!
The only reason I gave it one star is cuz there wasn't an option for zero stars! I used this on my Glock 17. Didn't fit as described the screws were too long first off. No problem I'm a machanicly inclined guy so I took them to the ole grinder and go them to the perfect length and put em on first screw set good but the second screw seemed like it stripped the threads so I didn't dare tighten any more. I did use locktite on everything as well. Let it set over night and tested it the next day. Second shot it flew off and hit me in the forehead!! Not to mention my optic went flying in the dirt!!! Save yourself alot of headaches and DONT BUY THIS PRODUCT!

Cost effective solution Vs Expensive Machining of non-MOS Glock slides
Just installed this on my G17 and I'm blown away by the fit, finish and ease of installation 20 min locked up tight and my Holosun HS407C attached with no issues. bore sighted , tested and excellent quality looks great. The best part is I can reverse it if needed. No expensive slide cut or MOS slide needed. Recommend this item to anyone. Disregard 99% of negative issues reported most are installer related not the plate
