The Glock 48 MOS, a compact 9mm pistol, has quickly gained popularity among concealed carry enthusiasts and competitive shooters alike. One key feature driving its appeal is its MOS (Modular Optic System), allowing for the easy mounting of various red dot sights. This guide delves into the world of Glock 48 MOS optics, exploring compatible sights, mounting considerations, and the overall impact on the shooting experience.
Understanding the Glock 48 MOS System
The Glock 48 MOS's modularity sets it apart. Instead of requiring custom machining or aftermarket slides, the MOS system incorporates a pre-milled slide with four mounting holes. This allows for the direct attachment of several red dot optics using the correct mounting plate. This significantly simplifies the process of adding an optic compared to other pistols requiring extensive modifications. The system's robustness ensures a secure and reliable fit, minimizing the risk of optic shift during recoil. This is crucial for maintaining accuracy and consistent point-of-aim.
Choosing the Right Optic
Selecting the right red dot sight for your Glock 48 MOS depends on several factors: your budget, intended use, and personal preference. Here are some popular choices:
- Holosun 507K/507C: These are incredibly popular due to their smaller footprint, making them ideal for the Glock 48's compact size. Their solar-powered capabilities and bright reticle are big pluses.
- Trijicon RMR: Known for its durability and reliable performance, the Trijicon RMR is a premium choice, offering excellent clarity and a wide range of reticle options. However, it tends to be more expensive than other options.
- Leupold DeltaPoint Pro: This optic offers a larger viewing window than the Holosun or RMR, which can be beneficial for some shooters. It's also known for its robust construction.
- Shield RMSc: A compact and lightweight option, the Shield RMSc is another popular choice, offering good value for its price and performance.
Note: Always verify that the chosen optic is compatible with the Glock 48 MOS and that you have the correct mounting plate.
Mounting Your Optic: A Step-by-Step Guide
Mounting a red dot sight on a Glock 48 MOS is generally straightforward, but precision is vital. Incorrect installation can lead to an insecure mount and potential accuracy issues. Here's a step-by-step guide:
- Gather your tools and materials: This includes the chosen optic, the appropriate MOS mounting plate for your optic, a torque wrench (crucial to avoid over-tightening), and potentially a gunsmithing punch or screwdriver.
- Select the correct mounting plate: Glock offers different mounting plates to accommodate different optics. Using the wrong plate will result in an improper fit and potential damage.
- Attach the mounting plate to the slide: Carefully align the mounting plate with the pre-milled holes on the Glock 48 MOS slide. Using the correct screws and a torque wrench, secure the plate firmly to the slide. Avoid over-tightening.
- Mount the optic: Align the optic with the mounting plate and secure it using the optic's mounting screws. Again, use a torque wrench to ensure proper tightening.
- Verify the zero: After mounting, head to the range to zero your optic. Start by shooting at a known distance to ensure the point of impact aligns with the point of aim.
Co-Witnessing Options: Iron Sights vs. Red Dot Only
One important consideration is whether to maintain co-witnessing capabilities. Co-witnessing allows the shooter to use both the red dot sight and the iron sights simultaneously. This provides a backup aiming system in case the red dot malfunctions. Some shooters prefer a lower 1/3 co-witness setup, where the iron sights are visible below the red dot. Others choose to use the red dot exclusively.
Table 1: Co-Witnessing Options
| Option | Description | Advantages | Disadvantages |
|---|---|---|---|
| 1/3 Co-Witness | Iron sights visible below the red dot sight | Backup aiming system, maintains familiarity with iron sights | Can obstruct the red dot sight in some positions |
| Absolute Co-Witness | Iron sights directly aligned with the red dot sight | Clear sight picture with both systems | Can be distracting |
| Red Dot Only | Removing the iron sights completely to maximize the red dot's visibility | Maximizes red dot visibility | No backup aiming system |
Impact on Concealed Carry and Competition
Adding a red dot sight to a Glock 48 MOS significantly impacts both concealed carry and competitive shooting.
- Concealed Carry: While the addition of the optic increases the overall size of the pistol slightly, the improved speed and accuracy offered by the red dot can compensate.
- Competition: The added precision provided by a red dot sight can lead to improved scores in various shooting disciplines, especially those requiring rapid target acquisition and accuracy under pressure.
Conclusion: Unlocking the Potential of Your Glock 48 MOS
The Glock 48 MOS opens up exciting possibilities for shooters looking to enhance their pistol's capabilities. By understanding the available optics, mounting procedures, and co-witnessing options, you can effectively customize your Glock 48 MOS to meet your specific needs and shooting style. Remember that proper installation and zeroing are crucial for optimal performance and safety.
