What Optics Fit the Glock 48 MOS? A Comprehensive Guide
The Glock 48 MOS (Modular Optic System) is a popular choice for concealed carry, offering the advantage of mounting a red dot sight for enhanced accuracy and speed. However, choosing the right optic can be confusing with so many options available. This guide will clarify which optics are compatible and help you select the best fit for your needs and shooting style.
Understanding the Glock 48 MOS Mounting System
The key to finding compatible optics lies in understanding the Glock 48 MOS's mounting system. The MOS model features a slide with pre-cut mounting holes designed to accept various optic plates. These plates act as adapters, allowing you to mount a wide range of mini red dot sights (RDS). Crucially, it's not the optic itself that needs to be "MOS-compatible," but rather the optic plate. Glock provides several different optic plates, each designed for specific optic footprints.
Common Optic Footprints and Compatible Optics
Several popular mini red dot sight footprints are compatible with the Glock 48 MOS via the correct adapter plate:
-
Shield RMSc (and RMSc-1): This is a popular and compact footprint, offering excellent compatibility with several manufacturers. Many consider this a great starting point for the Glock 48 MOS. Examples of optics utilizing this footprint include the SIG Sauer RomeoZero, Holosun 407K/507K (with the correct plate), and the Leupold DeltaPoint Pro.
-
Trijicon RMR Footprint: The Trijicon RMR is a well-respected name in the optics world, and many manufacturers offer optics with this popular footprint. While requiring a different Glock plate, it's a strong option for those prioritizing reliability and proven performance. The Trijicon RMR itself, as well as many other options from various brands, are compatible here.
-
Holosun 507K/407K Footprint (with adapter): While the Holosun 507K/407K can be used with the RMSc plate (using a specific adapter from companies like CHPWS), using the correct plate often offers a more secure and lower-profile mount.
Factors to Consider When Choosing an Optic
Beyond compatibility, consider these factors:
-
Size and Weight: The Glock 48 is known for its compact size. Choose an optic that complements this, avoiding excessively bulky options that could negatively impact concealability.
-
Battery Life: Battery life is crucial for any optic, especially on a concealed carry firearm. Look for optics with long battery life to minimize downtime.
-
Durability: An optic needs to withstand the rigors of daily carry and use. Consider materials, construction, and water/shock resistance ratings.
-
Brightness and Clarity: The clarity of the reticle and its brightness adjustment range are key for optimal performance in varying lighting conditions.
Finding the Right Plate and Optic: A Step-by-Step Approach
-
Identify your desired optic: Research different optics and choose one that fits your budget and requirements.
-
Determine the optic's footprint: Check the manufacturer's specifications to identify the footprint (e.g., Shield RMSc, Trijicon RMR).
-
Find the correct Glock optic plate: Ensure you purchase the correct plate from Glock or a reputable aftermarket supplier that matches your chosen optic's footprint.
-
Mount and test: Carefully install the optic plate and optic onto your Glock 48 MOS and verify proper function and zero.
Choosing the right optic for your Glock 48 MOS depends on your individual preferences and needs. By carefully considering the information provided above, you can select an optic that will enhance your shooting accuracy and reliability. Remember to always prioritize safety and follow proper gun handling procedures when mounting and using optics.
