Glock 19X MOS: Does It Exist?

Alright, guys, let's dive into the burning question: is there a Glock 19X MOS? For those not fluent in Glock-speak, MOS stands for Modular Optic System. Basically, it means the pistol comes with a slide cut from the factory, ready to accept a red dot sight. Now, the Glock 19X is super popular for its hybrid design – the full-size Glock 17 frame combined with the more compact Glock 19 slide. This combo gives you a better grip and control while keeping the overall package relatively concealable. So, naturally, a lot of folks have been wondering if Glock would ever release an MOS version of this beloved handgun.

First, let's set the stage. The original Glock 19X hit the market with a lot of fanfare. Its coyote tan finish, unique for a factory Glock at the time, and its excellent ergonomics made it an instant hit. People loved the balance and the way it felt in their hands. It quickly became a favorite for both everyday carry and recreational shooting. However, one thing was noticeably absent: an optics-ready slide. This omission left many shooters feeling like something was missing, especially as red dot sights were becoming increasingly popular on pistols. The ability to mount a red dot directly to the slide offers faster target acquisition and improved accuracy for many shooters. So, the demand for a Glock 19X MOS started building almost as soon as the original was released. People began looking for aftermarket solutions, sending their slides off to be milled, or exploring other options to add a red dot to their 19X. This aftermarket demand made it clear that there was a significant market for a factory-made Glock 19X MOS. Despite the clear demand, Glock remained silent on the issue for quite some time, leaving enthusiasts to speculate and hope. The lack of a factory MOS version seemed like a missed opportunity, considering how well-received the original 19X was and the growing popularity of pistol red dots in general. This led to numerous discussions in online forums, shooting communities, and gun stores, all centered around the question of when, or if, Glock would finally answer the call and release a Glock 19X MOS. The anticipation only grew stronger as other manufacturers continued to release optics-ready pistols, further highlighting the absence of this feature on the 19X. The debate was fueled by rumors and speculation, with many shooters expressing their desire for a factory-made solution that would maintain the reliability and durability that Glock is known for. Ultimately, the question of whether a Glock 19X MOS would ever see the light of day became a persistent topic among Glock enthusiasts, driving the demand and curiosity even higher.

So, What's the Deal? Does a Glock 19X MOS Exist?

Okay, here's the lowdown: as of my last update, Glock does NOT offer a factory-made Glock 19X MOS. I know, I know, it's a bummer. The Glock 19X continues to be produced with its standard slide, lacking the Modular Optic System. For those really wanting to add a red dot, you've generally had two main options: aftermarket milling or using an adapter plate.

Let's break down these options a bit more. Aftermarket milling involves sending your slide to a gunsmith who will then machine a slot into the slide to accommodate your chosen red dot sight. This is a more permanent solution, and when done by a reputable gunsmith, it can provide a very secure and low-profile mounting option. However, it does come with its own set of considerations. First, it's irreversible. Once the slide is milled, you're committed to using a red dot sight on that pistol. Second, it can be expensive, as you're paying for the gunsmith's time and expertise. Third, it can take time, as you'll be without your slide while it's being milled. Despite these drawbacks, many shooters opt for this route because it provides the most direct and secure mounting solution. The red dot sits lower on the slide, which can improve the sight picture and make it easier to find the dot quickly. Additionally, a properly milled slide will typically provide a tighter fit for the red dot, which can improve accuracy and reliability. This is why many serious shooters and competitive shooters prefer aftermarket milling, despite the cost and inconvenience. On the other hand, using an adapter plate is a simpler and less permanent solution. An adapter plate attaches to the existing dovetail on your slide (where the rear sight sits) and provides a platform for mounting your red dot. This option is generally less expensive and doesn't require any permanent modifications to your slide. However, it does have some drawbacks. The adapter plate raises the red dot higher above the bore axis, which can make it more difficult to find the dot quickly and can also affect the pistol's balance. Additionally, adapter plates can sometimes be less secure than a direct milling solution, which can lead to the red dot shifting or coming loose over time. Despite these drawbacks, adapter plates are a popular choice for shooters who want to try out a red dot on their Glock 19X without making any permanent modifications. They're also a good option for shooters who want to be able to easily switch between using a red dot and using the iron sights. Ultimately, the choice between aftermarket milling and using an adapter plate depends on your individual needs and preferences. If you're serious about using a red dot on your Glock 19X and want the most secure and low-profile mounting solution, then aftermarket milling is probably the way to go. However, if you're just looking to try out a red dot or want a less expensive and less permanent option, then an adapter plate might be a better choice.

Aftermarket Options: Making It Happen Yourself

Since Glock hasn't stepped up with a 19X MOS, the aftermarket has exploded with options. You can find companies that will mill your existing 19X slide to accept a red dot. This involves cutting a precise pocket into the slide to match the footprint of your chosen optic (like a Trijicon RMR or Holosun 507c). The upside? A super secure and low-profile mounting solution. The downside? It's permanent, and you'll be without your slide for a bit.

Alternatively, you can use adapter plates. These mount in the rear sight dovetail and provide a platform for your red dot. It's a less permanent solution, but it raises the optic higher, which some people don't like. When choosing an aftermarket milling service, it's essential to do your research and select a reputable company with experience in Glock slides. Look for companies that offer a warranty on their work and use high-quality machining equipment. The quality of the milling job will directly impact the reliability and accuracy of your pistol, so it's worth investing in a reputable service. Be sure to specify the exact red dot sight you plan to use, as different optics have different footprints. The gunsmith will need to know this information to ensure that the milling is done correctly. Also, consider whether you want any additional features, such as front serrations or a refinished slide. Some companies offer these services as part of their milling package. The turnaround time for aftermarket milling can vary depending on the company and the complexity of the job. Be sure to ask about the estimated turnaround time before sending in your slide. Once your slide is milled, you'll need to reinstall the internals and test the pistol to ensure that everything is functioning properly. It's always a good idea to take your pistol to a qualified gunsmith for this step if you're not comfortable doing it yourself. When it comes to adapter plates, there are many different options available on the market. Choose an adapter plate that is specifically designed for your Glock 19X and your chosen red dot sight. The adapter plate should be made from high-quality materials and should fit securely in the dovetail. Some adapter plates come with additional features, such as integrated rear sights. These can be useful if you want to maintain the ability to use iron sights as a backup to your red dot. Installing an adapter plate is typically a simple process that can be done at home with basic tools. However, it's important to follow the manufacturer's instructions carefully to ensure that the adapter plate is installed correctly. Once the adapter plate is installed, you'll need to mount your red dot sight and zero it in. This process is similar to zeroing in any other type of optic. Be sure to use a proper sight pusher tool to remove and install the rear sight, as using improper tools can damage the slide. Ultimately, the decision of whether to go with aftermarket milling or an adapter plate depends on your individual needs and preferences. Both options have their pros and cons, so it's important to weigh them carefully before making a decision.

Why No Factory Glock 19X MOS?

That's the million-dollar question, right? Why hasn't Glock released a 19X MOS? Honestly, it's mostly speculation. Glock is known for being… deliberate… in their product releases. They don't jump on every trend. Some theories suggest they didn't see enough demand initially. Others say it might have been related to production constraints or focusing on other models. Whatever the reason, the 19X MOS remains a void in the Glock lineup. Glock's approach to product development is often described as conservative and methodical. They prioritize reliability and durability over flashy new features, which may explain why they haven't rushed to release a Glock 19X MOS. The company has a long-standing reputation for producing firearms that are simple, robust, and dependable, and they are careful to maintain this reputation with each new product release. Another factor that may have influenced Glock's decision is the cost and complexity of adding the MOS feature to the 19X. The MOS system requires precise machining of the slide, which can add to the manufacturing cost. Additionally, Glock may have been concerned about the potential for the MOS system to compromise the reliability of the pistol. The company is known for its rigorous testing procedures, and they may have needed more time to ensure that the MOS system met their stringent standards. Furthermore, Glock may have been focusing on other models that they believed had a higher market potential. The company has a wide range of pistols in its lineup, and they may have decided to prioritize the development and production of models that they believed would be more popular with consumers. It's also possible that Glock was waiting to see how the market for pistol red dots evolved before releasing a Glock 19X MOS. The popularity of pistol red dots has grown significantly in recent years, but it's still a relatively new trend. Glock may have wanted to wait until red dots became more mainstream before investing in the development of an MOS version of the 19X. Despite the lack of a factory Glock 19X MOS, the aftermarket has stepped in to fill the void. Numerous companies offer aftermarket milling services for the 19X, allowing owners to add a red dot sight to their pistol. This has provided a viable option for those who want to combine the ergonomics and reliability of the 19X with the benefits of a red dot sight. Ultimately, the reasons behind Glock's decision not to release a 19X MOS remain largely speculative. However, it's clear that the company's conservative approach to product development, its focus on reliability, and its assessment of market demand all played a role in the decision. Whether Glock will eventually release a 19X MOS remains to be seen, but for now, the aftermarket continues to provide a solution for those who want to add a red dot sight to their beloved 19X.
