Upgrading your Glock 19 Gen 5 to a Modified Open Slide (MOS) configuration can be an exciting project, offering a blend of customization and enhanced performance. Here's a guide to help you navigate the process, ensuring your G19 MOS is not just functional but also aesthetically pleasing and tailored to your specific needs.
1. Choose the Right Optics
The first step in designing your G19 MOS is selecting the ideal optic. This choice will significantly impact your shooting experience and the overall look of your pistol. Consider factors like your shooting style, the environment you typically operate in, and your budget.
For instance, if you're a competitive shooter looking for precision at longer ranges, a high-end red dot sight like the Trijicon RMR or the Aimpoint PRO could be your best bet. These optics offer excellent clarity and durability, ensuring you can acquire targets quickly and accurately. On the other hand, if you're on a tighter budget or prefer a more traditional look, iron sights with a fiber optic front sight and a bright rear sight could be a great choice.
2. Select the Perfect Mount
Once you've chosen your optic, the next step is to select the right mount. The mount you choose should be compatible with your optic and ensure a secure and stable attachment to your pistol. There are various mounting options available, each with its own set of pros and cons.
If you're going for a minimalist look or have a limited budget, a low-profile mount like the Trijicon RMR Mount or the Burris Fastfire Mount might be ideal. These mounts keep the optic close to the slide, reducing the overall height of the pistol and maintaining a sleek profile. However, if you're looking for a more robust and versatile option, a full-size mount like the Burris Picatinny Rail Mount or the Vortex Viper Mount could be a better choice. These mounts offer more flexibility in terms of positioning and can accommodate a wider range of optics.
3. Optimize Slide Design
The slide of your G19 MOS plays a crucial role in its performance and aesthetics. Consider modifying the slide to enhance its functionality and appearance. One popular modification is the addition of slide cuts, which can improve the balance and handling of your pistol while also providing a unique visual element.
For example, you could opt for a window cut, which involves removing a section of the slide to reduce weight and provide a clear view of the optic. This modification not only improves the balance of the pistol but also adds a modern and tactical look. Alternatively, you might consider a cover cut, which involves cutting away a portion of the slide to accommodate a larger optic. This modification can provide a more stable mounting platform for your optic and give your pistol a more aggressive appearance.
4. Customize the Grip
The grip of your G19 MOS is essential for comfortable and accurate shooting. Consider customizing the grip to fit your hand perfectly and enhance your control over the pistol.
One popular modification is the addition of grip tape or stippling, which can improve your grip and reduce the risk of the pistol slipping from your hand. Stippling involves adding a series of small, textured bumps to the grip, providing a more secure hold. If you prefer a more subtle approach, you might consider adding grip tape, which can enhance your grip without altering the aesthetics of the pistol too drastically.
5. Enhance Trigger Pull
A smooth and consistent trigger pull is crucial for accurate shooting. Consider upgrading the trigger mechanism to improve the feel and performance of your G19 MOS.
There are various trigger upgrade kits available, ranging from simple drop-in replacements to more complex custom jobs. For example, the Glock OEM Connector Kit can reduce the trigger pull weight, making it easier to fire the pistol quickly and accurately. Alternatively, you might consider a complete trigger upgrade kit, which can include a new trigger bar, trigger spring, and other components, allowing you to customize the trigger pull to your exact preferences.
6. Improve Magazine Capacity
Increasing the magazine capacity of your G19 MOS can be a wise move, especially if you're planning to use the pistol for self-defense or competitive shooting.
There are several extended magazine options available, including those from Glock itself and third-party manufacturers like Magpul and MEC-GAR. These extended magazines can increase the capacity of your G19 MOS from the standard 15 rounds to 17 or even 20 rounds, giving you more firepower without significantly altering the balance or ergonomics of the pistol.
7. Add a Suppressor Height Sight
If you plan to use a suppressor with your G19 MOS, it's essential to ensure that your sights are compatible. A suppressor height sight is designed to maintain proper sight alignment even with a suppressor attached.
There are various suppressor height sights available, including fiber optic and tritium night sights. These sights are typically taller than standard sights, allowing them to clear the suppressor when it's attached. This modification ensures that you can still acquire targets quickly and accurately, even when using a suppressor.
Conclusion
Designing the ultimate Gen 5 G19 MOS involves a series of thoughtful choices and modifications. By carefully selecting the right optics, mount, slide design, grip, trigger, magazine capacity, and sights, you can create a pistol that's not only highly functional but also uniquely tailored to your needs and preferences. Remember, the key to a successful build is understanding your requirements and choosing components that work harmoniously together. With the right approach, your G19 MOS can become the ultimate shooting tool, ready for any situation.
