### ⭐⭐⭐⭐⭐ Perfect fit
*by I***3 on March 24, 2026*

Fits well on a Smith & Wesson M&P .22 paired with a Leapers utg red dot.

### ⭐⭐⭐⭐ Seems Solid, But There Could Be Installation Issues
*by S***5 on July 21, 2019*

This was purchased for a Glock 19 Gen 4, to mount the inexpensive UTG red dot sight. The Glock rear sight is removed, an insert installed into the dovetail slot, and the sight mounting base attached to the insert with two screws. This seems to be a solid platform, and my sight appears to be quite secure when mounted. A slight collar around each hole in the dovetail provides good indexing of the sight base. Mounting screws come with a bit of blue thread locker applied. The potential installation issue is that the insert is extremely tight in the dovetail slot - not much chance that the mount will drift sideways with use. This is similar to, or perhaps tighter than, a replacement sight. Fortunately I already had a sight pusher tool; I would not have been able to tap this insert into place with a mallet and drift punch. An alternative would be to file a bit off the insert, but it is small and may be difficult to work with. The "Ade Advanced Optics Glock Tactical Mini Dotx Sight Pistol Mount Base" (also sold on Amazon) may be a better option for those without sight pushers. My ADE dovetail insert for another Glock pistol fit loosely enough to be easily inserted by hand. The mounting base is slightly curved on the sides, conforming to a stock Glock slide to both capture the insert and to be self-centering. The base mounting screws tighten up the assembly and hold it in place. The UTG mount fits the ADE sight, and the ADE mount accommodates the UTG sight. This seems to be a somewhat "standard" pattern used by Burris, Docter, Vortex, and others. This type of mount can be very good for those who want to experiment with inexpensive red dots before buying higher-end sights and milled slides, though the sight will sit noticeably higher without slide milling. The UTG has been a high quality mount so far.
