Glock

Glock pistols have earned a reputation for reliability, simplicity, and near-zero maintenance that has made them the most trusted handgun on the planet. From the full-size Glock 17 to the slim Glock 43, the Gen 6 lineup represents the latest evolution of a design that has dominated law enforcement, military, and civilian markets since 1982. Whatever your use case—duty carry, concealed carry, competition, or home defense—there is a Glock configuration purpose-built for it.

Why Glock Dominates the Market

Introduced in 1982, Glock’s polymer-frame design was considered radical—today it’s the standard every other manufacturer competes against. The Safe Action trigger system fires only when the trigger is deliberately pulled, with three independent safety mechanisms that prevent firing from impact or dropping. The polymer frame requires no lubrication on most surfaces and survives conditions that would corrode or damage metal-frame pistols. Field stripping requires no tools and takes under a minute. These characteristics together explain why Glock remains the most-carried duty pistol by American law enforcement more than four decades after its introduction.

Glock Models at a Glance

The Glock lineup is organized by frame size and caliber. Full-size models like the G17 (9mm) and G21 (.45 ACP) offer the longest sight radius and highest capacity. Compact models—the G19, G23, and G32—balance shootability with concealment. The G19X and G45 combine the compact slide with a full-size grip for maximum capacity in a carry package. Subcompact models—the G26 and G27—are the most concealable. The slim single-stack models—G43X and G48—provide carry-optimized thinness in 9mm.

Glock Generation 6: What’s New in 2026

Glock introduced Generation 6 pistols in early 2026, debuting at SHOT Show and shipping to dealers by February. The Gen 6 updates include palm swells on both sides of the grip for enhanced purchase, stabilizing flats on the front and rear grip strap, a refined trigger with approximately 5.8 lb pull, and updated internal components. The Gen 6 G17, G19, and G45 are the initial release models.

Gen 5, Gen 6, and V-Series—What’s the Difference?

Gen 5 brought flared magwell, ambidextrous slide stop, and removal of finger grooves for a more universal grip. Gen 6 builds on that with palm swells, stabilizing flats, and refined trigger geometry. The V-Series (Glock 17V, 19V, etc.) applies Gen 5 specifications with enhanced accuracy components for precision shooting applications. For most buyers, Gen 5 and Gen 6 are both excellent—the Gen 6 improvements are meaningful but the Gen 5 remains a fully capable platform. The V-Series is for shooters who specifically want Glock’s competition-grade accuracy package.

Choosing the Right Glock Caliber

9mm is the overwhelming choice for most buyers—lower recoil, higher capacity, and modern defensive ammunition that matches or exceeds older larger-caliber loads. The .40 S&W G22 and G23 remain popular with buyers who prefer the cartridge or have department requirements. The G20 in 10mm Auto is the choice for buyers who want maximum handgun power for hunting or backcountry defense. The G21 in .45 ACP is the traditional full-size option for .45 buyers. The G40 in 10mm with its 6” barrel is Glock’s dedicated hunting pistol.

Glock for Concealed Carry

The G43X and G48 are Glock’s dedicated carry pistols—sharing the same slim frame profile with 10+1 flush capacity in 9mm. The G43X uses a shorter slide; the G48 adds a longer 4.17” barrel for more velocity and sight radius. Both accept Shield Arms S15 15-round magazines for dramatically increased capacity in the same frame. The G19 compact is the most popular concealed carry Glock for buyers who prioritize capacity over thinness. The G26 subcompact is the most concealable double-stack option.

Color and Cerakote Glock Variants

Glock produces an expanding range of factory color configurations beyond standard black and FDE—Sapphire Blue, Tiffany (robin’s egg blue), Glitter finishes, and Crushed Silver slides that have found a dedicated buyer base. Custom Cerakote variants are available through Glock’s retail partners in additional color combinations. For buyers who want a specific color combination, check the available configurations on each model page as color availability varies by model.

Competition Glocks: G34 and G17 MOS

The G34 is Glock’s dedicated competition pistol—a 5.31” barrel, extended slide, and lightened trigger that delivers the best out-of-the-box accuracy in the Glock lineup. The G17 MOS (Modular Optic System) provides optics mounting for USPSA Production Optics and other competition divisions. For USPSA, IDPA, and Steel Challenge competitors who want a factory competition Glock without aftermarket modifications, the G34 is the starting point.
