Factors To Consider When Buying The Best Red Dots for Glock 19 MOS
Dot Size and Reticle Options
The size of the red dot plays a crucial role in both speed and accuracy. A smaller dot, such as 2-3 MOA, allows for precise aiming at longer distances, making it ideal for precision shooting. Larger dots, like 6 MOA, offer quicker target acquisition but may obscure smaller targets at a distance. Some red dots also offer reticle options, such as a circle-dot combination, which can enhance versatility depending on your shooting needs.
Durability and Build Quality
A red dot sight for a Glock 19 MOS must be rugged enough to withstand the recoil of a handgun and harsh environmental conditions. Look for materials such as CNC-machined aluminum and reinforced shrouds that provide impact resistance. Water, shock, and fog resistance are also important factors, ensuring reliability in various weather conditions and tactical scenarios.
Battery Life and Power Management
Battery life can greatly affect the usability of a red dot sight. While some optics offer thousands of hours of continuous operation, others have shorter lifespans that require frequent replacements. Features like motion-activated illumination help conserve battery power by turning off the dot when inactive and instantly reactivating it upon movement. Side-loading or top-loading battery compartments are preferable to prevent loss of zero during battery changes.
Brightness Settings and Night Vision Compatibility
A red dot should have multiple brightness settings to adapt to different lighting conditions, from bright daylight to low-light or night environments. Adjustable brightness ensures the reticle remains visible without being too dim or overly glaring. If you use night vision devices, consider a sight that offers night vision-compatible settings to maintain visibility in complete darkness.
Mounting and Co-Witnessing Capability
Compatibility with the Glock 19 MOS mounting system is essential for a secure fit. Some optics require adapter plates, while others have direct mounting options. Additionally, a low-profile deck height allows for co-witnessing with standard iron sights, providing a backup aiming option in case of battery failure or optic damage. A good red dot should align properly with your preferred iron sight configuration, whether lower third or absolute co-witness.
Ease of Zeroing and Adjustment Precision
Precise windage and elevation adjustments are essential for maintaining accuracy. Click adjustments measured in MOA (Minutes of Angle) should be tactile and reliable, allowing for easy zeroing. Some sights offer tool-less adjustments, while others require a screwdriver or adjustment tool. A secure locking mechanism helps retain zero even after repeated recoil and handling.
Field of View and Lens Clarity
A wide field of view enhances situational awareness, allowing for quick target acquisition, especially in dynamic shooting scenarios. High-quality lenses with anti-reflective coatings minimize glare and distortion, providing a clear, crisp reticle. Distortion-free glass ensures that the target remains true to its actual position, improving shooting accuracy and confidence.
Size, Weight, and Concealability
A compact and lightweight red dot sight maintains the balance and handling of a Glock 19 MOS without adding unnecessary bulk. If using the firearm for concealed carry, a slim-profile sight is preferable to reduce printing and holster fitment issues. While larger optics may offer enhanced features, they can also affect concealment and overall firearm ergonomics. Choosing the right size ensures comfort and effectiveness in everyday carry or tactical use.
Best Red Dots for Glock 19 MOS Frequently Asked Questions
1) What is the ideal MOA size for a red dot on a Glock 19 MOS?
The ideal MOA size depends on your intended use. A 2-3 MOA dot provides better precision for longer-range shooting, while a 6 MOA dot offers faster target acquisition for self-defense or competitive shooting. A mid-range option like 2.5-4 MOA balances speed and accuracy, making it versatile for most shooters.
2) Do I need suppressor-height sights with a red dot on my Glock 19 MOS?
Suppressor-height sights are recommended if you want co-witnessing capability. They serve as a backup in case the red dot fails or the battery dies. Depending on the red dot’s mounting height, absolute or lower-third co-witnessing may be possible, ensuring you can still aim effectively without relying solely on the optic.
3) How long do red dot batteries last, and how easy is it to replace them?
Battery life varies depending on the brand and model, ranging from a few hundred hours to over 50,000 hours with efficient power management features like motion-activated illumination. Optics with top-loading or side-loading battery compartments make replacement easier without removing the sight, preventing loss of zero.
