Glock 19X

The Crossover Configuration

The 19X’s combination of a G17 frame with a G19 slide is deliberate and practical. The full-size frame gives every finger room on the grip and seats a 17-round magazine flush. The shorter G19 slide trims overall length to 7.44 inches and balances the pistol differently than either parent model. The result handles like a full-size gun with a slightly shorter barrel than the G17. Factory 19X and 19X V pistols come in a coyote finish on both frame and slide. The black Glock 45 uses the same frame-and-slide layout.

Glock 19X V: The V Series Version

The Glock 19X V keeps the 19X layout and coyote color on Glock’s V Series platform. Glock lists a 4.02-inch Glock Marksman Barrel, an nPVD slide coating, no finger grooves and ambidextrous slide stop levers. Its standard capacity is 17 rounds, with optional 19- and 24-round magazines. Glock lists a weight of 22.05 ounces without a magazine and a height of 5.47 inches. The 19X V ships with one 17-round magazine, two 17+2 magazines and a coyote pistol case. Versions with three 10-round magazines are also sold. Custom 19X V packages add a threaded barrel, a bronze-tone slide and an installed Vortex Defender-CCW red dot.

Factory Equipment

The original 19X came equipped with features many owners add to a standard Glock. Glock lists the Glock Marksman Barrel, an nPVD slide coating for corrosion resistance, ambidextrous slide stop levers, no finger grooves and a lanyard loop. Many 19X versions also carry Glock night sights, so check each listing for the sight type. Glock packs one standard 17-round magazine and two 17+2 magazines in a coyote case. A flared magwell helps guide the magazine during reloads.

Military Competition Background

The 19X grew out of Glock’s entry in the U.S. Army’s MHS (Modular Handgun System) competition, which ultimately selected the Sig Sauer P320 as the M17. Glock’s submission used the same crossover configuration. After the Army decision, Glock released the design to the civilian market. Standard 19X and 19X V pistols do not have a factory optics cut. Glock 19X MOS versions with a factory optics cut have also been offered, and some custom 19X V packages come with a slide cut and red dot already installed.

Who Should Buy the 19X

The 19X suits shooters who want the full-grip ergonomics of the G17 with a slightly shorter slide. It also fits buyers who like the coyote finish and want the factory equipment without aftermarket work. The full grip and 17-round standard capacity make it a common choice for home defense and duty-style use. Buyers who plan to add a red dot should look at a MOS version, a custom optic-cut 19X V package, or the G45 MOS.

19X vs. G45

The Glock 45 uses the same crossover configuration as the 19X, with a G17 frame and G19 slide. It comes in black, and the G45 MOS adds a factory optics cut. If you want a red dot on a black pistol, the G45 MOS is the simpler path. If you want the coyote finish and the 19X equipment package, choose a 19X or 19X V. The choice mostly comes down to color, equipment and optics plans.

Frequently Asked Questions: Glock 19X

What is the Glock 19X?
The Glock 19X is the result of Glock’s entry in the U.S. Army Modular Handgun System competition. It combines the compact Glock 19 slide with the full-size Glock 17 frame for a full-length grip. The result is a 17+1 capacity 9mm pistol with a shorter slide than the G17 and the full grip of a duty pistol. Glock released it commercially after the Army selected the Sig P320 (M17/M18).

What is the Glock 19X V?
The Glock 19X V is the V Series version of the 19X, with the same G17 frame, G19 slide and coyote color. Glock lists a 4.02-inch Glock Marksman Barrel, nPVD slide coating, no finger grooves and ambidextrous slide stop levers. It ships with one 17-round and two 17+2 magazines in most versions.

Is the Glock 19X V a Gen 5?
Glock calls it part of the V Series, which Glock announced in 2025 to replace many of its current models. Many retail listings, including several product names on this page, call it the 19X V Gen 5. Buyers searching for a Glock 19X Gen 5 or 19XV will find the same pistol.

What is the difference between the Glock 19X and the Glock 19X V?
Both use the G17 frame, G19 slide, 4.02-inch barrel and coyote finish. The 19X V is built on Glock’s newer V Series platform. Glock lists matching overall length, width, height and empty weight for the two pistols. Buy holsters and parts listed for the exact version you own.

Does the Glock 19X V have an optics cut?
Glock’s standard 19X V specifications do not list an optics cut. Custom 19X V packages on this page have a slide cut with a Vortex Defender-CCW red dot already installed. Check each listing for the optic and the sights.

What is the difference between the Glock 19X and Glock 45?
The G19X and G45 are mechanically very similar, and both combine the G19 slide with the G17 frame. The G19X has a coyote finish, an nPVD slide coating and ships with one 17-round and two 17+2 magazines. The G45 has a black finish. The original G45 also has front slide serrations that the original G19X lacks. For most buyers, the choice is finish preference.

What is the Glock 19X MOS?
The Glock 19X MOS (Modular Optic System) adds a factory-milled optics cut to the 19X slide. MOS slides accept popular red dot sights with the matching adapter plate. It suits buyers who plan to add a red dot now or later.

Does the Glock 19X use G17 magazines?
Yes. The G19X accepts standard Glock 17 17-round magazines as its flush-fit magazine. It also takes 17+2 and 33-round extended magazines. G19 15-round magazines fit but sit short of the base of the longer grip.
