Share
The Glock 19X MOS has caught the eye of gun owners by mixing Glock’s classic design with some thoughtful new touches. It borrows the best bits from Glock’s most popular models, so you get reliability with a few modern perks that really make a difference.
If you’re curious about modern handguns, it’s worth knowing what makes the Glock 19X MOS different from the crowd. It’s not just about looks—this pistol’s practical upgrades make it a favorite for a pretty wide range of shooters.
1) Coyote-colored frame with durable nPVD coating
The coyote-colored frame and slide instantly set the Glock 19X MOS apart from the usual black Glocks. That color gives it a tactical vibe, and, honestly, it just looks cool. Plenty of shooters appreciate the unique finish.
Glock covers the frame and slide with a special nPVD coating. This treatment fights off corrosion and shields the metal from wear, chemicals, and nasty weather. You can take this pistol out in just about any conditions, and it’ll hold up.
nPVD doesn’t add much weight or bulk, but it makes the finish tougher. That means less hassle keeping it clean and a longer life for the gun’s surface. Glock’s never done this color-and-coating combo before, so it’s a first, and it appeals to both civilians and pros who want a reliable, good-looking firearm. If you want more details, check the Glock 19X product page.
2) Combination of full-size GLOCK 17 frame and compact GLOCK 19 slide
The hybrid design is a standout here. Glock paired the full-size G17 frame with the shorter G19 slide, and the result is a gun that feels just right in the hand but doesn’t get bulky.
You get a comfortable, full grip and more magazine capacity, just like the G17. At the same time, the compact slide makes it lighter and easier to carry around. If you’ve got bigger hands, the full-size frame is a real plus, and the longer grip helps control recoil. There’s even a lanyard loop built in.
The shorter slide means you can draw from a holster faster, which is handy for duty or concealed carry. It balances well and feels nimble, too. This crossover approach is pretty popular with shooters who want the best of both worlds. If you’re curious, here’s more on the unique hybrid design of the Glock 19X.
3) MOS (Modular Optic System) for easy optics mounting
The Modular Optic System (MOS) lets you mount a red dot sight right onto the slide—no gunsmithing needed. Glock pre-cuts the slide and includes adapter plates, so you can add your favorite optic with just a few tools.
This setup works with most popular red dots, making upgrades or swaps pretty painless. Most folks can install or remove an optic themselves, no fuss. That flexibility means you can tweak your setup anytime new accessories drop or your preferences change.
The MOS system gives shooters a way to personalize their aiming system, which can boost accuracy and speed whether you’re training, competing, or thinking about self-defense. If you want to dig deeper, check out Glock’s page on easy optics mounting.
4) GLOCK Marksman Barrel (GMB) for improved accuracy
Inside, you’ll find the GLOCK Marksman Barrel (GMB). This barrel uses improved polygonal rifling and a new crown design.
The tighter chamber and better slide fit help lock things up more consistently, which translates to better accuracy. Glock first rolled out the GMB in its Gen 5 models, aiming for tighter groups and more precision. Plenty of users have noticed smaller group sizes compared to the older barrels.
The new barrel crown protects the rifling and helps the gun stay accurate over time. The GMB also strikes a nice balance between durability and reliability. If you want the nitty-gritty, here’s more about the GLOCK Marksman Barrel and its features.
5) Ambidextrous slide stop levers and no finger grooves
Glock put ambidextrous slide stop levers on the 19X MOS, so lefties and righties can both work the slide stop easily—no awkward grip changes needed.
Controls on both sides make it more user-friendly, especially if you’re sharing the gun or using it for training. Another big improvement: Glock ditched the finger grooves on the grip. The old grooves only fit certain hands, and, honestly, they could be pretty uncomfortable if your fingers didn’t line up just right.
Now, the grip is smooth, so it fits more hand sizes and shapes. Shooters get a more comfortable, secure hold, and the pistol adapts better to whoever’s using it. These ergonomic changes are showing up on other new Glocks too, and for good reason. More info’s on the GLOCK 19X product page.
Design Innovations in the Glock 19X MOS
Glock built the 19X MOS for comfort, control, and versatility. Every detail—from the frame shape to the ambidextrous controls—aims to work for all sorts of shooters and uses.
Ergonomic Frame and Texturing
The pistol uses a full-size frame from the G17, giving you more grip than most compacts. That extra grip helps with control, especially during rapid fire or when things get stressful. The design sits nicely in your hand, which helps with recoil and accuracy.
The grip’s texturing strikes a balance: it’s aggressive enough for a solid hold, even if your hands are sweaty or you’re wearing gloves, but not so rough that it’ll chew up your palm during long range sessions. With the finger grooves gone, the frame feels more adaptable for different hand sizes and shooting styles.
There’s a lanyard loop in the frame for extra retention. The coyote tan color and nPVD-coated slide fend off corrosion and wear, so you can take it out in just about any environment. If you want more, here’s an overview of the Glock 19X MOS design.
Ambidextrous Features
Glock made sure both right- and left-handed shooters can run this pistol comfortably. The ambidextrous slide stop lever lets you release the slide from either side, which helps with fast reloads and clearing malfunctions.
You can swap the magazine release to either side, so it fits your dominant hand. The controls are sturdy and close enough to reach without shifting your grip.
These features make the 19X MOS a flexible pick for shared use or pro settings where shooters might need to switch hands quickly. If you want a deeper look, here’s more about its ambidextrous and ergonomic options.
Compatibility and Customization Options
Glock designed the 19X MOS with flexibility and upgrades in mind. You can easily add new tech and accessories to make it work better for you.
Modular Optic System Integration

Glock includes several mounting plates, so you can fit optics from brands like Trijicon, Leupold, or Docter. The slide’s precision cut for these plates, so the fit’s solid. You can still use the iron sights as backup, too.
This setup makes the Glock 19X MOS a strong choice for shooters who want to add red dot optics. Whether you’re into competition, personal defense, or law enforcement, there’s room to customize.
Accessory Rail Enhancements
Under the barrel, you’ll find a Picatinny (or “universal”) rail. It lets you snap on lights, lasers, or other gear—no gunsmithing needed.
The rail supports standard sizes, so most attachments fit right on. That makes it easy to set up for home defense, range days, or duty carry.
Adding a light helps when you’re in the dark, and a laser can speed up point-and-shoot training. The accessory rail gives you options to personalize the pistol for whatever you need, making the Glock 19X MOS suitable for many roles.
