Unlocking Precision: Mastering the Glock 40 MOS Red Dot Setup
The Glock 40 MOS is a powerhouse pistol, and with the right red dot setup, you can elevate your shooting experience to new heights. Whether you're a competitive shooter or a hunting enthusiast, a well-configured red dot sight can make all the difference. Here are five essential tips to help you design the ultimate Glock 40 MOS red dot setup.
1. Choose the Right Red Dot Sight
Selecting the perfect red dot sight is the cornerstone of your setup. Consider factors such as durability, battery life, and field of view. Look for a sight with a clear, crisp reticle and a bright, adjustable LED. Some popular options include the Trijicon RMR, Leupold DeltaPoint Pro, and Holosun HS507C. Ensure the sight is compatible with the Glock MOS system and has a low-profile design for a sleek look.
2. Mounting Options
The mounting system is crucial for a secure and stable red dot setup. There are various mounting options available, including dovetail mounts, Picatinny rails, and proprietary systems like the Glock MOS plate. Ensure the mount is sturdy and provides a solid foundation for your red dot sight. Consider factors like ease of installation, height adjustment, and compatibility with your chosen sight.
Mounting Plate Compatibility:
- Glock MOS Plate: Ensure the plate is specifically designed for the Glock 40 MOS.
- Aftermarket Plates: Explore options from brands like TLR, Shield, or other reputable manufacturers.
3. Co-Witnessing: Aligning Iron Sights
Co-witnessing allows you to align your red dot sight with the iron sights on your Glock 40 MOS. This ensures that you have a backup sighting option and can quickly switch between the two. There are two types of co-witnessing: 1) absolute co-witness, where the red dot and iron sights are aligned at the same height, and 2) lower 1/3 co-witness, where the red dot is slightly lower than the iron sights.
Tips for Co-Witnessing:
- Practice: Familiarize yourself with both sighting options to ensure quick and accurate transitions.
- Height Adjustment: Some red dot sights offer height adjustment, allowing you to fine-tune the co-witnessing setup.
4. Battery Life and Power Management
Red dot sights rely on batteries, so choosing a sight with good battery life is essential. Look for sights with long-lasting batteries or the option to use common battery types like CR2032 or AA. Additionally, consider power-saving features such as auto-shutoff or brightness adjustment to extend battery life during extended periods of non-use.
Battery Tips:
- Carry Spare Batteries: Always have spare batteries on hand, especially for longer shooting sessions.
- Battery Life Indicator: Some sights have a battery life indicator, providing a visual cue when it's time to replace the battery.
5. Zeroing and Sight Adjustment
Zeroing your red dot sight is crucial for accurate shots. Ensure your sight is properly zeroed at the desired distance, typically 25 yards or 50 meters. Most red dot sights offer windage and elevation adjustments, allowing you to fine-tune the point of impact. Take your time during the zeroing process to ensure precision.
Zeroing Tips:
- Start with a Rest: Use a shooting rest or bag to minimize movement and ensure a stable platform during zeroing.
- Boresighting: Consider boresighting your Glock 40 MOS to get an initial alignment before fine-tuning with live fire.

FAQ
What is the MOS system on the Glock 40, and why is it important for red dot setups?
+The MOS (Modular Optic System) on the Glock 40 allows for easy installation and removal of various optic sights, including red dots. It provides a standardized mounting platform, ensuring a secure and consistent setup. This system simplifies the process of adding or changing optic sights, making it ideal for shooters who want flexibility in their setup.
Can I use a red dot sight without co-witnessing iron sights?
+Yes, you can use a red dot sight without co-witnessing iron sights. However, having a backup sighting option is beneficial, especially in situations where the red dot sight may fail or in low-light conditions. Co-witnessing provides a quick and reliable alternative, ensuring you’re never left without a sighting system.
How often should I zero my red dot sight, and what are the signs it needs re-zeroing?
+It’s recommended to zero your red dot sight after any significant changes, such as switching ammunition types or after heavy use. Signs that your sight needs re-zeroing include noticeable shifts in point of impact or inconsistency in your shots. Regularly check your zero to ensure accurate and precise shooting.
