Glock 19

Why the G19 Is the Default Recommendation

The Glock 19 succeeds by doing everything adequately and nothing poorly. It's compact enough for concealed carry under most clothing without being so small that it's difficult to shoot accurately. Fifteen rounds is enough capacity for virtually any defensive scenario. The 4.02-inch barrel is long enough for accurate shooting at distance. The polymer frame and striker-fired action require minimal maintenance. The enormous aftermarket means every accessory, holster, sight, and trigger modification is available. The G19 accepts G17 magazines for 17-round capacity when concealment isn't required. For anyone who wants one pistol that does everything, the G19 has been that answer for decades.

Glock Generation 6: What Changed from Gen 5

Glock's Generation 6 update reached dealers in January 2026, with the G17, G19 and G45 in the first group. The Gen 6 frame adds a palm swell, a thumb rest above the trigger guard and a new Gen6 grip texture — subtle changes that improve grip consistency during the draw and presentation. Every Gen 6 pistol comes optic-ready with Glock's own mounting system and a flat-faced trigger. Glock lists the G19 Gen 6 with a 4.02-inch barrel, a 15-round standard magazine and a weight of 20.11 ounces without a magazine. The trigger pull is listed at 26 N, about 5.8 lbs. Holsters and accessories from the major manufacturers are being updated for the reshaped grip, so confirm Gen 6 compatibility when purchasing a new holster if you're upgrading from Gen 5.

Glock 19 V: The V Series Version

Glock announced the V Series in October 2025, when it replaced many of its earlier models with new V versions. The Glock 19 V keeps the compact G19 size. Glock lists the GLOCK Marksman Barrel, an nDLC finish, front slide serrations, no finger grooves and interchangeable backstraps. The magazine catch is reversible, and the slide stop lever is ambidextrous. Standard capacity is 15 rounds, and Glock lists optional 17-, 24-, 31- and 33-round magazines. Glock's G19 V specifications do not list a factory optics cut. See the full lineup on our Glock V Series page.

Gen 5 Improvements

The Gen 5 G19 brought meaningful improvements over earlier generations. The finger grooves were removed from the frontstrap, making the grip more universally comfortable for different hand sizes and shooting styles. The flared magwell improves reload speed. The ambidextrous slide stop accommodates left-handed shooters without modification. The Marksman barrel delivers improved accuracy over the polygonal rifling of previous generations. The nDLC finish improves corrosion resistance. For buyers choosing between a used earlier-generation G19 and a new Gen 5, the Gen 5 improvements are real and the price difference is typically modest—the Gen 5 is the right choice for most buyers who want a proven generation. Gen 4 pistols keep the finger grooves and introduced interchangeable backstraps, and Gen 3 pistols have a fixed grip size. Many custom Cerakote G19s on this page are built on Gen 5 or Gen 3 pistols, so check each listing for the generation.

G19 MOS—The Optics-Ready Version

The Glock 19 Gen 5 MOS is the recommended configuration for any buyer who intends to run a red dot on a Gen 5 pistol. The factory-milled slide accepts Glock MOS adapter plates for Trijicon RMR, Holosun 507c, Leupold DeltaPoint Pro, and other popular footprints. Running a red dot on a carry G19 provides a genuine accuracy advantage, particularly for low-light defensive scenarios and for shooters with presbyopia who struggle to focus on a front sight. The MOS configuration is available at a modest price premium over the standard Gen 5 and is worth the difference for any buyer who is serious about optics-equipped carry. Gen 6 pistols are optic-ready from the factory with Glock's newer mounting system, so check each listing for supported optics before you buy a red dot. Browse compatible optics on our Red Dot Sights page.

Glock 19X and 19X V on This Page

The Glock 19X and 19X V are listed here because they share the G19 slide and 4.02-inch barrel. They pair that slide with the full-size G17 frame, which holds a 17-round magazine flush. Both come in a coyote finish, and the 19X V is the V Series version of the design. The longer grip makes the 19X harder to conceal than a standard G19. For full details, including factory equipment and the 19X vs. G45 comparison, see our Glock 19X page.

Concealed Carry

The G19 is concealable for most people with appropriate clothing and a quality holster. IWB appendix carry is the most popular configuration for the G19, with the compact slide length preventing barrel printing at the thigh. Strong-side hip carry works well with looser cover garments. The G19 is on the larger end of what most people can comfortably pocket carry, though some carry it in jacket pockets with a proper holster. For warm-weather carry under minimal clothing, the Glock 43X or LCP Max may be more practical. For most other carry situations, the G19's capacity and shootability advantages over smaller guns make the slightly more intentional concealment worthwhile.

Competition and Training

The G19 is a staple of USPSA Production division competition and dominates law enforcement training programs. The combination of stock trigger, reliable operation, and competition-legal capacity makes it competitive in Production without modification. The vast aftermarket means a competition G19 can be incrementally upgraded over time without replacing the pistol. For new shooters, the G19's combination of manageable size, low recoil, and Glock's simple manual of arms makes it one of the best training pistols available at any price point. Learning to shoot a G19 well translates to competence on virtually every other striker-fired pistol.

Frequently Asked Questions

Why is the Glock 19 the most popular pistol in America?
The Glock 19 hits the ideal balance point between full-size and compact — its 15+1 capacity and 4-inch barrel give it near-full-size performance in a package most people can conceal. It is the most widely issued law enforcement sidearm in the US, has one of the deepest aftermarkets of any pistol, and its mechanical simplicity means almost nothing can go wrong with it. Those factors compound into a self-reinforcing standard that makes it the default recommendation for most buyers.

What is the difference between the Glock 19 Gen 5 and Gen 6?
The Gen 6 adds a palm swell, a thumb rest, a new grip texture and a flat-faced trigger. Every Gen 6 is optic-ready from the factory, while the Gen 5 needed the MOS version for an optics cut. Barrel length and 15-round standard capacity are the same. Holsters may fit differently because of the reshaped Gen 6 grip.

What is the Glock 19 V?
The Glock 19 V is the V Series version of the G19, introduced after Glock's October 2025 lineup change. Glock lists the Marksman Barrel, nDLC finish, front serrations, no finger grooves, interchangeable backstraps and an ambidextrous slide stop lever. Standard capacity is 15 rounds.

What is the difference between the Glock 19 Gen 4 and Gen 5?
The Gen 5 adds an improved barrel with a Marksman polygonal rifling profile for better accuracy, a flared magwell for faster reloads, ambidextrous slide stop, and removes the finger grooves from the grip for a more universally comfortable hold. The Gen 5 trigger also has a smoother break than Gen 4. Gen 4 and Gen 5 holsters and parts are not always interchangeable, so match them to your pistol. Glock's newer Gen 6 and V Series pistols are also current production.

What is the difference between the Glock 19 and the Glock 19X?
Both use the same compact slide and 4.02-inch barrel. The 19X puts that slide on the full-size G17 frame, so it has a longer grip and a 17-round standard magazine. The 19X and 19X V come in coyote; most standard G19s are black. See our Glock 19X page for details.

What is the difference between the Glock 17 and Glock 19?
In Glock's Gen 6 specifications, the G17 has a 4.49-inch barrel, a 17-round standard magazine, a 7.95-inch overall length and a 5.47-inch height. The G19 has a 4.02-inch barrel, a 15-round standard magazine, a 7.28-inch overall length and a 5.04-inch height. The G19 is easier to conceal, and the G17 has a longer sight radius.

Is the Glock 19 good for concealed carry?
The Glock 19 is the benchmark compact carry pistol. It is slightly larger than true subcompacts like the Glock 43X or Sig P365, which means it prints more under light clothing — but it carries 15 rounds versus 10, shoots better under stress due to more grip surface, and is generally easier to shoot accurately. Most serious concealed carriers who don't face extreme clothing restrictions choose the G19 over smaller alternatives.

How many rounds does a Glock 19 hold?
The standard Glock 19 magazine holds 15 rounds, for 15+1 with a round chambered. Glock also lists 17-, 24-, 31- and 33-round magazines for the G19 V. G17 17-round magazines fit and function in the G19 but extend below the grip. Versions with 10-round magazines are sold for capacity-restricted states.

What is the Glock 19 MOS?
The Glock 19 MOS (Modular Optic System) has a factory-milled slide cut that accepts red dot sights with the matching Glock adapter plate. It was offered on Gen 5 pistols. Gen 6 pistols come optic-ready as standard with Glock's newer mounting system.

Does Impact Guns carry the Glock 19?
Yes. The Glock 19 Gen 5 is one of our most consistently carried models at our Ogden and Boise stores. See our full Glock brand page for the complete lineup.
