The Glock 20, known for its robust build and powerful 10mm Auto cartridge, has gained even more versatility with the introduction of the MOS (Modular Optic System). This system allows for easy mounting of red dot sights, significantly enhancing the pistol's accuracy and usability for various applications, from hunting and competitive shooting to self-defense. This guide delves into the Glock 20 MOS and the benefits of adding a red dot sight.
Understanding the Glock 20 MOS
The Glock 20 MOS is essentially a standard Glock 20 with a modified slide. The MOS slide features a milled area that accepts various red dot sight mounting plates. This allows for a seamless integration of the optic without needing custom gunsmithing or aftermarket modifications. This modularity is a key selling point, offering flexibility to choose the red dot sight that best suits your needs and budget.
Key Features of the Glock 20 MOS:
- Modular Optic System (MOS): This is the defining feature, enabling quick and easy installation of various red dot sights using readily available mounting plates.
- 10mm Auto Caliber: The powerful 10mm cartridge delivers impressive stopping power, making it suitable for hunting, self-defense, and competitive shooting.
- Durable Construction: Like all Glocks, the 20 MOS is built with durable polymer and a robust metal slide, ensuring reliability and longevity.
- High Capacity Magazines: Standard magazines hold 15 rounds, providing ample firepower. Extended magazines are also available.
- Ambidextrous Controls: The slide release, magazine release, and other controls are ambidextrous, making the pistol comfortable for both right- and left-handed shooters.
Why Add a Red Dot Sight to Your Glock 20 MOS?
Adding a red dot sight to your Glock 20 MOS offers several significant advantages:
-
Improved Accuracy: Red dots provide a clear, unobstructed sight picture, leading to faster target acquisition and improved accuracy, particularly at close to medium ranges. This is especially crucial in dynamic shooting situations.
-
Faster Target Acquisition: The use of a red dot eliminates the need to align three separate elements (front and rear sights, and target) as in traditional iron sights. This significantly reduces target acquisition time, a crucial factor in self-defense scenarios.
-
Enhanced Shooting Experience: Many users find red dot sights more comfortable and intuitive to use, especially for extended shooting sessions. The reduced eye strain and improved sight picture contribute to a more enjoyable shooting experience.
Types of Red Dot Sights Compatible with Glock 20 MOS:
The Glock MOS system is compatible with a wide range of red dot sights from various manufacturers. Popular choices include:
- Trijicon RMR: Known for its ruggedness and reliability.
- Leupold DeltaPoint Pro: Offers excellent clarity and battery life.
- Holosun 507K/508T: Affordable options with good performance.
- SIG Romeo1 Pro: Compact and lightweight.
Choosing the right red dot depends on factors like budget, intended use, and personal preference. Consider features such as battery life, durability, and the size and weight of the optic.
Case Study: Glock 20 MOS with Trijicon RMR in Competition
A competitive shooter using a Glock 20 MOS with a Trijicon RMR reported a significant improvement in his scores. He cited the faster target acquisition and improved accuracy as key factors. He also found the red dot sight more comfortable for extended shooting sessions. This highlights the practical benefits of adding a red dot to a Glock 20 MOS for competitive shooting.
Conclusion: Unlocking the Potential of the Glock 20 MOS
