Choosing the right red dot sight for your Glock can significantly enhance your shooting accuracy and speed. Two of the most popular options are those using the Glock Modular Optic System (MOS) and those designed for the Trijicon RMR footprint. Understanding the differences between these footprints is crucial for making an informed decision. This comprehensive guide will delve into the specifics, helping you choose the best fit for your needs.
Understanding the Glock MOS System
The Glock MOS (Modular Optic System) was introduced to provide a factory-integrated solution for mounting red dot sights directly onto Glock pistols. Instead of relying on aftermarket solutions that often involved milling the slide, the MOS system features pre-cut slide milling for easy and secure mounting. This ensures a robust and reliable attachment point, eliminating potential issues associated with aftermarket modifications. Glock offers different MOS plates to accommodate various red dot sight footprints, making it a versatile option.
Advantages of the Glock MOS System:
- Factory-Integrated: Offers a clean, factory-integrated solution, preserving the pistol's original aesthetics and integrity.
- Easy Installation: The system simplifies installation, requiring minimal gunsmithing skills.
- Robust Mounting: The factory-designed mounting plates provide secure and reliable attachment.
- Versatility: Different MOS plates allow compatibility with various red dot sight footprints.
Understanding the Trijicon RMR Footprint
The Trijicon RMR (Ruggedized Miniature Reflex) sight has become a highly popular and respected choice among shooters. Its compact size, rugged construction, and reliable performance have made it a favorite for both law enforcement and civilian use. Many red dot sights are designed to match the RMR's footprint, offering a wide range of options for users.
Advantages of the RMR Footprint:
- Wide Availability: A vast selection of red dot sights are designed to fit the RMR footprint, offering choices in features, price points, and performance characteristics.
- Compact Size: The RMR's compact design makes it ideal for concealed carry and smaller pistols.
- Ruggedness: Known for its durability and resistance to harsh conditions.
- Proven Reliability: The RMR has a strong track record of reliable performance in various situations.
Glock MOS Footprint vs. RMR Footprint: Key Differences
While many red dot sights are compatible with both systems (due to the availability of adapter plates), the core difference lies in the mounting system itself. The MOS system is a Glock-specific solution integrated directly into the slide, while the RMR footprint is a standard utilized by many manufacturers.
| Feature | Glock MOS | Trijicon RMR Footprint |
|---|---|---|
| Mounting | Glock-specific, factory-integrated plates | Various manufacturers, adapter plates often used |
| Versatility | Limited to sights compatible with MOS plates | Wide range of compatible sights |
| Installation | Generally easier, factory-designed | Can require more precise fitting & potentially adapter plates |
| Cost | May influence the overall cost of the pistol | Sight selection influences overall cost |
Choosing the Right Footprint for Your Needs
The best choice depends on your priorities and specific needs.
-
For ease of installation and a factory-integrated solution, the Glock MOS system is a strong contender. It simplifies the process and offers a clean look.
-
For maximum choice and compatibility with a vast array of red dot sights, the RMR footprint is more versatile. This allows you to choose from a wider range of options based on your budget, desired features, and performance requirements.
Ultimately, consider factors like your budget, the features you need in a red dot sight, and your comfort level with installation when making your decision. Researching specific red dot sights compatible with each footprint will further refine your selection process.
