The Glock 19 MOS (Modular Optic System) is a popular choice for both law enforcement and civilian shooters, offering a versatile platform for customization and improved accuracy. Its ability to accommodate a wide range of red dot sights significantly enhances its capabilities in various shooting disciplines, from home defense to competitive shooting. This guide dives deep into the world of custom Glock 19 MOS builds, exploring popular modifications and considerations for optimizing your firearm.
Understanding the Glock 19 MOS Platform
Before diving into customization options, let's understand the foundation: the Glock 19 MOS. This pistol features a slide milled to accept various mini red dot sights (RDS) using readily available adapter plates. This modularity is a key selling point, allowing shooters to choose the optic best suited to their needs and budget. The inherent reliability and ease of maintenance of the Glock 19 platform are further amplified by the MOS system.
Popular Custom Glock 19 MOS Modifications
Customizing a Glock 19 MOS involves a range of options, from simple upgrades to extensive overhauls. Here are some of the most popular modifications:
1. Optics Selection: The Heart of Your Custom Build
Choosing the right red dot sight is crucial. Factors to consider include:
- Dot Size: Smaller dots offer precision, while larger dots provide faster target acquisition.
- Window Size: A larger window improves visibility, especially in low-light conditions.
- Battery Life: Longer battery life reduces downtime during critical situations.
- Durability: A robust optic is essential for reliable performance under stress.
Popular choices include the Trijicon RMR, Leupold DeltaPoint Pro, and Holosun 507K/508T, each offering a unique set of features.
2. Trigger Upgrades: Enhancing Control and Accuracy
Upgrading the trigger is a common modification that significantly impacts the shooting experience. Aftermarket triggers offer improvements in:
- Pull Weight: A lighter, smoother trigger pull improves accuracy and reduces trigger fatigue.
- Reset: A shorter, more tactile reset allows for faster follow-up shots.
Several reputable manufacturers offer high-quality Glock 19 triggers, including Apex Tactical Specialties, Ghost Inc., and Overwatch Precision.
3. Sights: Complementary to Your Optic
While a red dot sight is the primary aiming system, backup iron sights are crucial. Night sights offer enhanced visibility in low-light environments. Consider choosing sights that co-witness with your red dot, allowing for a seamless transition if your optic fails.
4. Enhanced Grip: Improved Control and Comfort
Improved grip is key for controlling recoil and achieving better accuracy. Consider these options:
- Stippling: Adding texture to the grip enhances grip security. This can be done professionally or as a DIY project.
- Aftermarket Grips: Several manufacturers offer aftermarket grips with improved ergonomics and texture.
5. Magazines: Extended Capacity and Reliability
Upgrading magazines offers several benefits:
- Increased Capacity: Extended magazines provide greater ammunition capacity.
- Improved Reliability: High-quality magazines ensure flawless feeding and function.
6. Slide Modifications: Enhancing Aesthetics and Performance
Slide modifications focus on enhancing performance and aesthetics:
- Slide Milling: Custom milling can reduce weight and enhance the aesthetic appeal of your pistol.
- Slide Cerakote: Cerakote is a durable coating that protects the slide from wear and tear and offers customization options.
