Glock 19X MOS: Does It Exist? What You Need To Know

The Glock 19X MOS is a question that often pops up among Glock enthusiasts. The simple answer is no, Glock does not currently offer a 19X model with a Modular Optic System (MOS) configuration directly from the factory. However, that doesn't mean you're out of luck if you're looking to mount a red dot sight on your 19X. Let's dive deeper into why there isn't a factory-made 19X MOS and explore the available alternatives for adding an optic to this popular pistol.

The Glock 19X, known for its coyote brown finish and hybrid design (a Glock 19 slide with a Glock 17 frame), has gained a dedicated following for its comfortable grip and balanced handling. Many shooters appreciate the longer grip of the G17 frame, which allows for a more secure and controlled hold, while the shorter slide of the G19 makes it easier to conceal. This combination has made the 19X a popular choice for both everyday carry and range use. Despite its popularity, Glock has not yet released a version with the MOS cut, which allows for the direct mounting of various red dot sights. This absence has led many to seek aftermarket solutions to equip their 19X pistols with optics.

So, why hasn't Glock released a 19X MOS? There's no official word from Glock, but we can speculate. Glock might have initially focused on other models for MOS adaptation, prioritizing those with higher demand for optics-ready configurations. Additionally, the 19X was initially marketed as a crossover pistol, emphasizing its hybrid design and reliability without necessarily targeting the optics-ready market. However, given the increasing popularity of red dot sights on pistols, it's certainly possible that Glock could release a 19X MOS in the future. For now, enthusiasts will have to rely on aftermarket options to fulfill their desire for an optic-mounted 19X. These options include slide milling services, adapter plates, and even purchasing aftermarket slides that are already cut for optics. Each of these approaches has its own pros and cons, which we'll explore in more detail below. Whether Glock will eventually introduce a factory-made 19X MOS remains to be seen, but the demand is clearly there, and the aftermarket has stepped in to fill the gap.

Alternatives for Mounting an Optic on Your Glock 19X

Since a factory Glock 19X MOS isn't available, what are your options for adding a red dot sight? You've got a few choices, each with its own set of pros and cons. Let's break them down so you can make the best decision for your needs and budget.

1. Slide Milling

Slide milling involves taking your existing 19X slide to a gunsmith who will then machine a specific footprint (like Trijicon RMR, Holosun 507k, etc.) directly into your slide. This is arguably the most popular and cleanest-looking solution. The biggest advantage? A super low-profile mounting, which means your red dot sits as close to the bore axis as possible. This can improve accuracy and make it easier to find your dot quickly. Another plus is that you get to choose the exact optic footprint you want, ensuring a perfect fit. However, slide milling is permanent. Once the slide is cut for a specific optic, you're pretty much stuck with it unless you get another milling job done. It also means you'll be without your slide for a period, typically a few weeks, while the work is being completed.

Cost is also a factor, as slide milling can range from $150 to $300 depending on the gunsmith and the complexity of the job. Make sure you choose a reputable gunsmith with experience in milling Glock slides to avoid any potential issues. It's also worth noting that milling can potentially void your Glock warranty, so check with Glock beforehand if this is a concern. Despite these potential drawbacks, slide milling remains a popular choice for those seeking a professional and permanent solution for mounting an optic on their Glock 19X. The low-profile design and customized fit make it a worthwhile investment for many shooters looking to enhance their pistol's performance.

2. Adapter Plates

Adapter plates are another way to mount an optic, and while there's no Glock 19X MOS from the factory, this method attempts to mimic that modularity. These plates attach to the rear of your slide, usually by replacing the rear sight. The red dot then mounts on top of the plate. The upside? It’s generally cheaper than milling and doesn't permanently alter your slide. You can also switch between different optics by swapping out the adapter plate, offering some flexibility. However, there are downsides. Adapter plates raise the optic higher above the bore axis compared to milling. This can sometimes make it harder to find the dot quickly and may require adjusting your shooting technique. Also, some adapter plates aren't the most robust and can potentially loosen over time with repeated firing.

The market offers a wide variety of adapter plates, with prices typically ranging from $30 to $100. When selecting an adapter plate, it's crucial to choose a reputable brand known for quality and durability. Look for plates made from robust materials like steel or aluminum and ensure they are specifically designed for your Glock 19X. It's also wise to read reviews and seek recommendations from other Glock owners to gauge the reliability and performance of different adapter plates. While adapter plates offer a convenient and affordable solution for mounting an optic, it's important to be aware of their potential limitations in terms of height and durability. Consider your shooting style and intended use when deciding whether an adapter plate is the right choice for your needs. Despite their drawbacks, adapter plates can be a good option for those seeking a non-permanent and budget-friendly solution for adding an optic to their Glock 19X.

3. Aftermarket Slides

Aftermarket slides come pre-cut for optics, essentially giving you a Glock 19X MOS experience without the official Glock stamp. You simply swap out your factory slide with the aftermarket one. The benefit? You get a dedicated optics-ready slide without modifying your original. Plus, aftermarket slides often come with other enhancements like improved serrations or different coatings. The drawback? Cost. Aftermarket slides can be a significant investment, often costing as much or more than slide milling. Also, you need to ensure the aftermarket slide is compatible with your 19X frame and functions reliably.

The price of aftermarket slides can vary widely, ranging from $200 to $500 or even more, depending on the brand, features, and materials used. When choosing an aftermarket slide, it's essential to research reputable manufacturers known for producing high-quality and reliable Glock components. Look for slides made from durable materials like stainless steel and ensure they are specifically designed for the Glock 19X platform. It's also crucial to consider the optic cut compatibility and choose a slide that matches the footprint of your desired red dot sight. While aftermarket slides offer a convenient and customizable solution for adding an optic to your Glock 19X, it's important to weigh the cost and ensure compatibility and reliability before making a purchase. Despite the higher price tag, aftermarket slides can be a worthwhile investment for those seeking a dedicated optics-ready solution with enhanced features and aesthetics.

Choosing the Right Option

So, which route should you take to get that Glock 19X MOS feel? It really depends on your priorities:

• Budget: Adapter plates are the most affordable, followed by slide milling, with aftermarket slides being the most expensive.
• Permanence: Slide milling is permanent, adapter plates are reversible, and aftermarket slides allow you to keep your original slide intact.
• Profile: Slide milling offers the lowest profile, followed by aftermarket slides, with adapter plates having the highest profile.
• Features: Aftermarket slides often come with enhanced features, while slide milling allows for customization, and adapter plates are generally basic.

Consider what's most important to you and choose the option that best fits your needs. No matter which path you choose, adding an optic to your Glock 19X can enhance its versatility and improve your shooting performance. Each method offers a unique set of advantages and disadvantages, so it's essential to weigh your options carefully and select the one that aligns with your budget, preferences, and intended use. Whether you opt for the low-profile design of slide milling, the affordability of adapter plates, or the enhanced features of aftermarket slides, the end result is a more capable and customizable Glock 19X that's ready for any shooting scenario.

Conclusion: The Future of the Glock 19X and Optics

While there's no official Glock 19X MOS yet, the aftermarket provides plenty of ways to add an optic to this popular pistol.
