Let’s Talk About Leapers UTG Super Slim RDM20 Mount – Glock Rear Sight Dovetail
The Leapers UTG Super Slim RDM20 Mount – Glock Rear Sight Dovetail offers a low-cost, readily available solution for mounting a micro red dot sight to your Glock. Leapers UTG, known for their budget-friendly tactical accessories, aims to provide an accessible option for those wanting to experiment with red dots without breaking the bank. I picked this up when I wanted to test a red dot on my Glock 19 without milling the slide.
After years of sticking with iron sights, I was curious to see how a red dot would improve my target acquisition speed. I needed an affordable and non-permanent way to mount one to my Glock 19. The Leapers UTG mount seemed like the perfect solution. Opening the package, I was surprised by how lightweight the mount was, constructed of what appeared to be decent quality aluminum.
Compared to other dovetail mounts I’ve seen, like those from Trijicon or Suarez International, this one clearly prioritizes affordability over premium materials. I chose this mount over the others primarily because of its price point. My initial thought was cautiously optimistic, hoping it would perform adequately despite its budget-friendly nature.
Real-World Testing: Putting Leapers UTG Super Slim RDM20 Mount – Glock Rear Sight Dovetail to the Test
First Use Experience
I first tested the mount at my local indoor shooting range. I wanted a controlled environment to zero the red dot and assess the mount’s stability. After installing the mount and my UTG RDM20 micro red dot (separately purchased), I got to work at the range.
The initial zeroing process was straightforward, though the dot seemed to shift slightly after the first few magazines. I tested it in various lighting conditions, and the mount held steady for about 50 rounds. After that I noticed some wiggle on the mount.
Extended Use & Reliability
After several range sessions and a few hundred rounds fired, the Leapers UTG Super Slim RDM20 Mount – Glock Rear Sight Dovetail showed some wear and tear. I tightened the set screws frequently to maintain zero, however, the mount never truly felt secure. The matte black finish began to wear around the edges where it contacted the slide.
Maintenance was simple – a quick wipe down with a cloth after each range trip was sufficient. Compared to my experience with direct-milled slides, this mount simply did not offer the same level of reliability. I was ultimately disappointed with the long-term performance.
