Glock 19 MOS Vs Glock 19 Buying Guide
Optics Compatibility
The primary difference lies in optics compatibility. The Glock 19 MOS (Modular Optic System) is specifically designed to accept a variety of red dot sights directly from the factory. This is achieved through interchangeable adapter plates that mount to the slide. The standard Glock 19, however, lacks this feature and requires aftermarket modifications, such as slide milling, to accommodate an optic. Consider your desire for an optic and the associated costs and installation complexity when choosing between these two models. The MOS offers a streamlined, ready-to-go solution.
Slide Milling and Customization
For those who prioritize customization, the standard Glock 19 presents more options. While the MOS allows for easy optic mounting, the standard Glock 19 can be milled to accept a wider range of optic footprints and slide modifications, such as custom slide cuts and coatings. This allows for a more personalized aesthetic. However, this process involves professional services and potentially voids the factory warranty. The MOS offers a balance, but the standard 19 provides more freedom for extensive modifications.
Cost Considerations
The Glock 19 MOS generally carries a slightly higher price tag than the standard Glock 19 due to the added features and manufacturing processes. When factoring in the cost, consider the cost of adding an optic to a standard Glock 19, which includes the price of slide milling or a new slide. While the upfront cost of the MOS is higher, it can potentially save money in the long run if you plan to mount an optic. Evaluate your budget and desired features to determine the most cost-effective option.
Shooting Experience
The shooting experience is largely similar between the two models, as both share the same frame, grip, and internal mechanisms. The primary difference arises from the presence of an optic on the MOS, which can enhance target acquisition and accuracy, especially at longer ranges. The added weight of an optic may also slightly affect recoil management. Without an optic, the shooting experience is nearly identical. Personal preference for optics will greatly influence this factor.
Concealed Carry
Both models are excellent choices for concealed carry due to their compact size and reliable performance. The MOS, with an optic, may slightly increase the overall size and weight, potentially affecting concealment. However, advancements in holster design have minimized this impact. The standard Glock 19, being slightly slimmer and lighter, may offer a marginal advantage in certain carry scenarios. Consider your body type, preferred carry position, and holster choice when making your decision.
Availability and Accessories
Both the Glock 19 MOS and the standard Glock 19 are widely available. Both are supported by a vast aftermarket of accessories, including holsters, magazines, triggers, and other components. The MOS may have a slightly smaller selection of specific aftermarket parts due to its more recent introduction. The standard Glock 19, being a more established model, often has greater selection in specific areas. However, both have ample support.

Frequently Asked Questions
What does MOS stand for?
MOS stands for Modular Optic System. This designation indicates that the Glock 19 MOS is designed to easily accept a variety of red dot sights. The modularity comes from interchangeable adapter plates that allow the user to mount different optics without requiring slide modifications. This offers a convenient solution for those wanting to use a red dot.
Can I put an optic on a standard Glock 19?
Yes, but it requires modifications. You’ll need to have the slide milled to accept a specific optic footprint, or purchase a complete aftermarket slide that is already cut for an optic. This process adds cost and removes the factory finish. It’s often recommended to have a professional gunsmith perform this work.
Are the Glock 19 and Glock 19 MOS the same size?
Yes, the Glock 19 and Glock 19 MOS share the same frame dimensions. The MOS slide is slightly thicker due to the optic mounting system. The difference is minimal. The handling and concealability are nearly identical. Most holsters designed for a standard Glock 19 will also fit the MOS variant.
Which is better for beginners?
Both models are excellent for beginners. The Glock 19 MOS offers the advantage of an optic, which can improve accuracy and target acquisition. The standard Glock 19 is simpler and more straightforward, but the addition of an optic is a useful skill. The choice really depends on the individual’s preferences and budget.
Does the MOS affect reliability?
The MOS system is designed to maintain the Glock’s renowned reliability. The adapter plates are designed to be secure and the optic is mounted firmly. Ensure the optic is properly installed and maintained. There is no significant difference in reliability between the Glock 19 and Glock 19 MOS when used as designed.
Can I use the same magazines for both models?
Yes, both the Glock 19 and the Glock 19 MOS use the same magazines. They are compatible with Glock 19 magazines and any aftermarket magazines designed for the Glock 19 platform. This allows for convenient use of existing magazines. The magazines are interchangeable between the two models.
Is the MOS worth the extra cost?
That depends on your needs. If you want to use a red dot sight, the MOS is a more convenient and often more cost-effective option. If you don’t plan to use an optic, the standard Glock 19 will suffice. Consider the cost of slide milling, and the potential value of improved accuracy.
Final Verdict
The Glock 19 MOS offers a factory-ready solution for mounting optics, providing improved target acquisition and potentially enhanced accuracy. While the standard Glock 19 requires aftermarket modifications for optics, it offers more customization options. Considering the added convenience and value of the MOS, it is the better choice for most users.
