The Glock 19 MOS (Modular Optic System) has rapidly become a favorite among both competitive shooters and everyday carry enthusiasts. Its adaptability, combined with the legendary reliability of the Glock 19 platform, makes it an ideal canvas for customization. But where do you start when building your dream custom Glock 19 MOS? This comprehensive guide explores the key areas of customization and helps you navigate the process.
Understanding the Glock 19 MOS Platform
Before diving into customization options, let's understand what makes the Glock 19 MOS unique. The "MOS" designation signifies its pre-cut slide, designed to accept various mini red dot sights (MRDS) using readily available mounting plates. This eliminates the need for extensive gunsmithing, allowing for easy optic integration. This adaptability is a major factor driving its popularity.
Key Areas for Glock 19 MOS Customization
Customizing your Glock 19 MOS involves several key areas, each impacting performance, aesthetics, and overall usability:
1. Optics Selection: The Heart of Your Custom Build
Choosing the right optic is paramount. Factors to consider include:
- Size and Weight: Larger optics offer wider viewing windows but add weight and bulk. Smaller optics are more compact but might have smaller windows.
- Battery Life: Longer battery life is crucial for reliability. Consider optics with auto-shutoff features.
- Durability: The optic should withstand recoil and the rigors of daily use. Look for rugged, impact-resistant models.
- Personal Preference: Some shooters prefer certain reticle styles over others. Consider your shooting style and preferences.
Popular choices include the Trijicon RMR, Leupold DeltaPoint Pro, and Holosun 507K/508T.
2. Trigger Enhancement: Improving Your Shooting Experience
Upgrading the trigger is a common modification to enhance both accuracy and comfort. Options range from drop-in triggers that require minimal gunsmithing to more extensive trigger jobs performed by professional gunsmiths. Consider these aspects:
- Trigger Pull Weight: A lighter trigger can improve accuracy, but excessively light triggers can be unsafe.
- Trigger Reset: A shorter, crisper reset improves follow-up shot speed.
- Trigger Shoe: Different trigger shoe shapes and materials offer varying degrees of comfort and control.
3. Sights: Enhancing Target Acquisition
While the red dot sight is the primary aiming system on a Glock 19 MOS, supplemental sights are crucial for backup in case of optic failure ("co-witnessing"). Consider:
- Night Sights: For low-light shooting situations.
- Suppressor Height Sights: Necessary if you plan to use your Glock 19 MOS with a suppressor.
- Fiber Optic Sights: For enhanced visibility in daylight conditions.
4. Grips and Accessories: Enhancing Control and Comfort
Grips significantly impact your shooting experience. Consider:
- Texture: Aggressive textures improve your grip, even with sweaty hands.
- Size and Shape: Ergonomic grips can enhance comfort and control.
- Material: Different materials offer varying degrees of grip and feel.
Beyond grips, consider adding accessories such as extended magazine releases, flared magwells, and weapon lights for improved functionality.
5. Slide and Frame Refinements: Aesthetics and Performance
While functional upgrades are key, aesthetic customization is a popular choice. This includes:
- Cerakote Coatings: Durable coatings protect your firearm from wear and tear while allowing for a wide range of color and finish options.
- Custom Slide Engraving: Personalize your Glock with unique engravings or designs.
Building Your Custom Glock 19 MOS: A Step-by-Step Approach
- Define Your Needs: What will you primarily use your customized Glock 19 MOS for? (Home defense, concealed carry, competition shooting, etc.) This will influence your choices.
- Budget Wisely: Customization can range from relatively inexpensive to quite expensive. Establish a budget beforehand.
- Research Components: Carefully research optics, triggers, sights, and grips to find components that meet your needs and budget.
- Choose a Qualified Gunsmith (if needed): Some modifications require professional expertise. Find a reputable gunsmith with experience working on Glocks.
- Assemble and Test: Once your custom Glock 19 MOS is built, thoroughly test it to ensure all components are functioning correctly and reliably.
Building a custom Glock 19 MOS allows for personalization and optimization to suit your individual shooting style and preferences. Remember to prioritize safety and reliability throughout the customization process. This detailed guide provides a foundation, but always consult professional gunsmiths and relevant safety resources as needed.
