Factors To Consider When Buying The Best Red Dots for Glock 17
Durability and Build Quality
When selecting a red dot for your Glock 17, durability should be a top priority. A high-quality red dot sight should be built from rugged materials like aluminum or reinforced polymer to withstand recoil, impact, and harsh environmental conditions. Enclosed emitter designs provide additional protection against dirt, moisture, and debris, making them ideal for duty or defensive use. Look for models that are shockproof, waterproof, and fogproof to ensure reliable performance in all weather conditions. A robust red dot can endure thousands of rounds without losing zero, making it a dependable choice for both professional and recreational shooters.
Dot Size and Reticle Clarity
The size of the red dot, measured in MOA (Minutes of Angle), affects accuracy and target acquisition speed. A smaller dot, such as 2 MOA, allows for greater precision at longer distances but may be harder to see quickly in high-stress situations. Larger dots, around 6 MOA, are easier to pick up for fast shooting but can obscure small targets. A 3-4 MOA dot is often a balanced choice, providing a good mix of speed and accuracy. Additionally, a high-quality optic will have a crisp, well-defined dot without excessive blooming or distortion, ensuring a clear sight picture.
Battery Life and Accessibility
Battery life is a critical factor, as you want a red dot that can run for extended periods without frequent changes. Modern red dots offer thousands of hours of battery life, with some lasting over a year on a single battery. Look for models with energy-saving features like auto shutoff or motion-activated illumination to extend battery performance. Additionally, the battery compartment’s placement matters—top or side-loading designs allow for easy replacement without removing the sight, while bottom-loading options require re-zeroing after battery changes. A low-battery indicator can also be useful for preventing unexpected power loss.
Brightness Settings and Night Vision Compatibility
A good red dot sight should offer multiple brightness settings to adapt to different lighting conditions. A daylight-bright dot ensures visibility in direct sunlight, while lower settings prevent glare in dim environments. If you plan to use night vision equipment, check for dedicated night vision-compatible settings. The ability to quickly adjust brightness levels using easily accessible buttons is crucial, especially in dynamic shooting scenarios. Some optics have auto-adjusting brightness, but manual control is preferred by many users for consistency and personal preference.
Mounting Compatibility and Footprint
Not all red dots fit every optic-ready pistol out of the box, so ensuring compatibility with your Glock 17 is essential. Most red dot sights use specific mounting footprints, such as the RMR, ACRO, or Docter footprint. If your pistol’s slide is already cut for a particular footprint, choosing a matching red dot minimizes the need for additional adapter plates. Some models include multiple mounting options or plates, increasing their versatility. If you are using a Glock MOS (Modular Optic System) model, verify which adapter plates are needed to mount your chosen optic securely.
Weight and Size
A red dot sight should enhance your shooting experience without adding unnecessary bulk to your firearm. A lightweight optic helps maintain the balance of your Glock 17, ensuring a natural shooting feel. While larger sights may offer a bigger window for faster target acquisition, they can also be more obtrusive and affect concealability for those using their Glock for everyday carry. Compact red dots that minimize tunnel vision while maintaining a generous field of view provide the best balance of usability and practicality.
Parallax and Eye Relief
A good red dot should be parallax-free or have minimal parallax shift, ensuring that the point of aim remains consistent regardless of the shooter’s eye position. Unlimited eye relief is another critical factor, allowing shooters to maintain quick target acquisition and consistent sight alignment without having to precisely position their eye behind the optic. This is particularly beneficial in high-stress situations or when shooting from unconventional positions. Checking for minimal distortion around the edges of the sight window can also improve clarity and accuracy.
Price and Value for Money
Red dot sights range from budget-friendly options to high-end models used by military and law enforcement. While price often reflects quality, it’s important to assess whether a sight offers the features you truly need. A higher price may provide better durability, clearer optics, and longer battery life, but there are also well-built, affordable options that perform exceptionally well. Consider your intended use—whether for self-defense, competition, or range shooting—and invest in a red dot that balances quality and functionality within your budget.
