Why Red Dots Matter: Advantages of Red Dot on Your Glock 20 MOS
Accuracy Amplified
The decision to equip your Glock 20 MOS with a red dot optic is a strategic one, representing a fundamental shift in how you engage targets. This shift offers significant advantages over traditional iron sights in almost every aspect of marksmanship.
Improved accuracy is the first, most noticeable benefit. Red dot optics eliminate the inherent limitations of iron sights, namely the need to align the front sight, rear sight, and target. This alignment can be challenging, especially under stress or in dynamic situations. With a red dot, your focus stays on the target, and the red dot itself becomes the aiming point. This simplified process allows you to achieve faster and more precise shot placement. Parallax error, a common concern with iron sights, is virtually eliminated with a quality red dot.
Speed and Efficiency
Faster target acquisition is another critical advantage. The red dot is instantly visible, allowing you to acquire the target quickly, minimizing the time between drawing your firearm and taking a shot. This is crucial in self-defense situations. Instead of the time-consuming process of aligning iron sights, your eye instinctively seeks the dot, making target engagement much faster and more natural. The faster you can get on target, the better.
Low-Light Performance
Enhanced low-light performance is another critical consideration. Iron sights can become difficult or impossible to see in low-light conditions. The luminous dot of a red dot optic, however, remains visible, providing a clear aiming point even when ambient light is limited. This can be a critical advantage in home defense scenarios or any situation where you might encounter reduced visibility.
User-Friendly
User-friendliness for all is a significant attribute of the red dot. Red dots simplify the aiming process, making them easier to learn and master. This can be a tremendous benefit for new shooters. For experienced shooters, a red dot allows them to perform even faster, further improving their accuracy. This means you can spend more time training and less time struggling to achieve consistency. The simplicity and clarity that red dots offer leads to more efficient training.
Choosing the Right Red Dot: A World of Options
Factors to Consider
The market is brimming with excellent red dot options, so selecting the perfect one for your Glock 20 MOS requires careful consideration.
Size and weight are key considerations. The Glock 20 MOS is a full-size handgun, so you can generally accommodate a larger optic without compromising balance or handling. However, excess weight on the slide can affect the gun’s recoil characteristics, so find a balance between size, battery life, and the feature set.
Battery life and power source should be factors. A red dot with a long battery life minimizes the frequency with which you need to change batteries. Look for features like auto-off functions and energy-efficient circuitry. Be sure to carry spare batteries.
Durability is a vital consideration, especially given the recoil generated by the 10mm Auto cartridge. The optic must be able to withstand the constant pounding. Research brands that are known for robust construction and materials. Look for optics that have been tested for shock resistance.
Dot size (MOA) and brightness settings should be optimized for your intended use. The MOA (Minute of Angle) measurement defines the size of the dot at a given distance. A smaller dot (e.g., 2-3 MOA) is excellent for precision work at longer ranges, while a larger dot (e.g., 4-6 MOA) may be preferable for faster target acquisition at closer ranges. Adjustable brightness settings allow you to adapt to varying lighting conditions.
Red Dot Styles
Consider these popular red dot optic styles:
Miniature red dot sights (MRDS) are compact, lightweight options that are a great choice for any Glock 20 MOS. They are designed for handguns, and they often feature excellent battery life and rugged construction.
Enclosed red dot sights offer superior protection from the elements and provide a more robust design. They are less likely to get obscured by dirt, rain, or snow.
Reflex sights have a more exposed design, often making them lighter. They may offer a wider field of view.
