1. Monstrum Dovetail Red Dot Mounting Plate for Glock Pistols | for Non-MOS Version Glock 17 19 20 21 22 23 34 35 40 41 45 47 | Compatible with Holosun 407k/507k/RMSc Footprint Red Dots

When I first came across the Monstrum Dovetail Red Dot Mounting Plate for Glock Pistols, I immediately recognized its potential to elevate the shooting experience for Glock owners, especially those with the non-MOS versions of popular models like the Glock 17, 19, 20, 21, 22, 23, 34, 35, 40, 41, 45, and 47. This mounting plate is specifically designed to fit seamlessly into the dovetail slot on the rear of the slide, replacing the fixed rear sight. This feature alone makes it a game-changer for anyone wanting to upgrade their Glock with a red dot sight without the need for expensive slide milling or complicated modifications.

One of the standout advantages for me is its compatibility with some of the most popular red dot footprints on the market today, including Holosun’s 407k, 507k, and RMSc models. This broad compatibility ensures that users aren’t restricted to one brand or model of red dot and can choose the optic that best suits their needs and budget. Additionally, the plate supports Docter and RMR footprints, which means it accommodates a wide range of optics beyond just Holosun.

All you need is a sight pusher tool to remove the fixed rear sight, which is a standard tool many Glock owners already have or can easily obtain. The process feels clean and straightforward, saving time and avoiding permanent modifications to the slide. For those who value reversibility and ease of installation, this is a significant benefit.

Material quality is a key consideration when it comes to firearm accessories, and Monstrum has delivered here by using hard anodized 6061-grade aluminum. This choice ensures durability and resistance to wear and corrosion, which is essential for a component that will be subjected to recoil, environmental elements, and frequent handling. The anodized finish also adds a sleek, matte look that blends well with Glock slides. The recommended torque specification of 15 in/lbs gives clear guidance to ensure the mount is secure without risking damage.

What truly gave me confidence in this product is Monstrum’s commitment to quality, backed by their lifetime guarantee on all mounts and accessories. This assurance means that if I ever encounter an issue with the mounting plate, I have the peace of mind that Monstrum stands behind their product.

How a Glock 43 Red Dot Mount Helps Me Improve My Shooting

When I added a red dot mount to my Glock 43, it completely changed my shooting experience for the better. The compact size of the Glock 43 makes it perfect for concealed carry, but its small sights can sometimes make quick target acquisition challenging. With the red dot mount, I find that I can acquire my target faster and with greater accuracy, especially in low-light conditions or under stress.

The red dot sight allows me to keep both eyes open while aiming, which improves my situational awareness and reduces tunnel vision. This has made a big difference when I’m practicing defensive shooting or just working on my speed at the range. The mount is solid and doesn’t add much bulk, so my Glock 43 stays lightweight and easy to carry every day. Overall, installing a red dot mount has made me more confident in my shooting and better prepared for any situation.

Buying Guide for Glock 43 Red Dot Mount

Understanding the Importance of a Red Dot Mount

When I first decided to enhance my Glock 43 with a red dot sight, I quickly realized that having a reliable mount is crucial. The mount serves as the foundation, securely attaching the optic to my pistol slide. Without a proper mount, my red dot sight wouldn’t stay aligned, affecting accuracy and overall performance.

Compatibility with Glock 43

One of the first things I checked was whether the mount was specifically designed for the Glock 43. Since this model has its unique slide dimensions, not all mounts fit perfectly. I made sure the mount was either a direct fit or required minimal slide milling, so I could install it without compromising the integrity of my firearm.

Material and Durability

Durability matters a lot to me because I want my setup to withstand regular use and recoil. Most quality mounts are made from aircraft-grade aluminum or steel. I preferred a mount that balanced strength with lightweight design to avoid adding unnecessary bulk to my pistol.

Mounting Method

There are different mounting methods available, such as plates that replace the rear sight or mounts that require slide milling. Since I wanted an easier installation, I looked for a mount compatible with the Glock MOS (Modular Optic System) or one that could be installed with minimal modifications. This saved me time and avoided expensive gunsmithing.

Co-Witness and Sight Picture

For me, co-witnessing the red dot with iron sights provides a backup if the optic fails. Some mounts allow for a lower or absolute co-witness, meaning the red dot sits in perfect alignment with my iron sights. I chose a mounting height that suited my shooting style and ensured a clear sight picture.

Height and Profile

The height of the mount affects how the red dot lines up with my natural sight picture. A lower mount keeps the optic closer to the slide, which I found more comfortable for quick target acquisition. However, a higher mount can help clear suppressors or compensators if I use them.

Ease of Installation and Adjustability

I valued mounts that came with all necessary hardware and clear instructions. Some mounts offer adjustable screws or modular designs, allowing fine-tuning for a perfect fit. Being able to install or remove the mount without specialized tools made maintaining my Glock 43 much easier.

Price vs. Quality

While I wasn’t looking to overspend, I recognized that investing in a quality mount pays off in reliability and performance. Cheaper mounts might save money upfront but could loosen or wear out quickly. I balanced cost with reviews and material quality to find the best value.

Additional Features

Some mounts come with added features like anti-rotation tabs or integrated recoil lugs, which help keep the optic secure under heavy use. I also looked for mounts that didn’t interfere with holstering, ensuring I could carry my Glock 43 comfortably.

Final Thoughts

Choosing the right red dot mount for my Glock 43 was about ensuring fit, durability, and ease of use. By focusing on compatibility, material quality, and installation method, I found a mount that improved my shooting experience without unnecessary complications. Taking the time to research and understand these factors made a big difference in my satisfaction with the setup.
