Glock Models for Gen 6: Detailed Comparison, Features & Upgrades

When Glock announces a new generation, the internet loses its mind for about 48 hours. Some guys swear it’s revolutionary. Others say it’s the same gun with a different number stamped on the slide. When Gen 6 dropped in December 2025, it felt like one of those moments again. But once you actually pick one up, you realize this isn’t just a cosmetic refresh. The grip feels different. The trigger feels different. The slide setup is clearly built around red dots from the start. Whether you love Glock or you’ve always been on the fence, Gen 6 is one you actually need to handle before forming an opinion.

Glock made a big change in December 2024 when they announced their sixth generation of pistols. The Gen 6 lineup launched with three models for the U.S. market: the G17, G19, and G45, all chambered in 9mm. These aren't just minor updates to existing guns. Glock redesigned key parts of the pistol based on hand measurements from people of different sizes.

The new generation brings improvements you can feel when you pick up the gun. The Gen 6 features include a palm swell that fits your hand better, updated grip texture called RTF6, and an enlarged beavertail for a higher grip. You also get a flat-faced trigger, improved slide serrations, and an optic-ready system with three plates included. The MSRP is set at $745, and each pistol comes with three magazines, a speed loader, and a cleaning set.

If you own a previous generation Glock or you're thinking about buying your first one, understanding what makes Gen 6 different matters. The changes affect how the gun feels in your hand, how easy it is to control, and how quickly you can add an optic. This guide breaks down each model and every new feature so you can decide if Gen 6 is right for you.

Gen 6 Glock Model Lineup

Glock released three Gen 6 pistols for the U.S. market at launch: the G17, G19, and G45, all chambered in 9mm with an MSRP of $745-$749. The G49 is available exclusively for international markets.

Glock G17 Gen 6

The G17 Gen 6 is Glock's full-size 9mm pistol with a 4.49-inch barrel. This model gives you a 17-round magazine capacity and represents the foundation of the Gen 6 lineup.

You get the complete suite of Gen 6 ergonomic upgrades including the RTF6 grip texture, flat-face trigger, and enlarged beavertail. The full-size grip frame provides maximum control during shooting.

The G17 ships with the new Refined Optic Ready System (ORS) and three optic plates. This mounting system allows your red dot to sit deeper in the slide compared to the old MOS system. You can mount optics directly to the slide or use the included polymer plates for RMR, DeltaPoint Pro, and Holosun K footprints.

Glock G19 Gen 6

The G19 Gen 6 is Glock's compact 9mm model with a 4.02-inch barrel and 15-round capacity. This pistol balances concealability with shootability, making it one of the most popular carry options.

Your G19 includes all the same ergonomic features as the G17. The compact slide and shorter grip make it easier to conceal while maintaining acceptable sight radius. The deeper front and rear slide serrations help you manipulate the slide in wet or dry conditions.

The ambidextrous gas pedals come standard and feature the same RTF6 texturing as the grip. You also get the redesigned flared magwell that makes reloads smoother and faster.

Glock G45 Gen 6

The G45 Gen 6 combines the full-size G17 grip with the compact G19 slide and barrel. This crossover design gives you 17-round capacity in a more compact package.

You get the best of both worlds with this model. The full-size grip provides better control and higher capacity while the shorter slide improves concealability. The integrated palm swell and deeper trigger guard undercut enhance your hand placement.

All internal updates apply to the G45, including the single captive recoil spring system and sealed extractor design. The flat-face trigger has a 5.5-pound pull weight straight from the factory.

International Model: Glock 49 Gen 6

The G49 is a Gen 6 model designated for overseas markets rather than domestic U.S. sales. Glock has not released this pistol in the United States.

Limited information is available about the G49's specific dimensions or capacity. The pistol includes the same Gen 6 features as the domestic models, including the ORS optic mounting system and ergonomic upgrades. International buyers can access this model through authorized dealers in their regions.

Frame and Grip Innovations

The Gen 6 frame introduces significant ergonomic improvements that address longstanding user feedback. These changes include a new texture pattern, refined grip contours, integrated safety features, and a factory undercut that collectively enhance control and comfort.

RTF6 Grip Texture and Coverage

The RTF6 texture represents a middle ground between the aggressive RTF2 pattern and the milder textures found on Gen 4 and Gen 5 models. This new pattern provides better grip in wet, dirty, or contaminated conditions while reducing the risk of abrading your clothing or skin during concealed carry.

The RTF6 texture now covers more surface area than previous generations. You'll find it extends to new areas like the thumb rest, giving you more contact points for a secure hold.

Glock designed this texture to be toothy and sticky without being unpleasantly rough. The increased coverage ensures you maintain positive control in adverse conditions without the discomfort that made the RTF2 pattern unpopular with many shooters.

Palm Swell and Ergonomics

The Gen 6 grip profile features a subtle taper in the thumb rest area, creating what Glock calls a palm swell. This modification makes the frame marginally less bulky than the Gen 5, improving fit for shooters with smaller hands.

The refined frame geometry provides a more natural point of aim and a generally more secure feel. You'll notice the difference especially when shooting with gloves, as the contoured design accommodates various hand sizes better than previous generations.

Despite these changes to the palm swell and overall ergonomics, your Gen 6 pistol maintains full compatibility with existing Gen 5 holsters. Glock included additional backstraps without the integrated beavertail, allowing you to adjust trigger reach based on your hand size and shooting preferences.

Enlarged Beavertail and Slide Bite Prevention

Glock integrated a factory-molded enlarged beavertail into the Gen 6 frame. This feature enhances your control during recoil and prevents potential contact between the slide and your hand during firing.

The beavertail design addresses the common issue known as slide bite, where the reciprocating slide contacts the web of your hand. By extending higher on the frame, this integrated component creates a protective barrier without adding bulk to the overall profile.

You can remove this feature by swapping to the included backstraps that don't have the beavertail. This flexibility lets you customize the pistol based on your grip style and whether you experience slide bite with your shooting technique.

Enhanced Undercut Trigger Guard

The Gen 6 frame includes a factory undercut trigger guard for the first time in Glock's production lineup. This modification was previously only available through aftermarket custom shops and significantly improves weapon control.

The undercut allows you to achieve a higher grip on the pistol, bringing your hand closer to the bore axis. This positioning reduces muzzle flip and helps you manage recoil more effectively during rapid fire.

By eliminating what many shooters called the "Glock knuckle"—the uncomfortable pressure point where the trigger guard met the frame—this design change improves comfort during extended shooting sessions. The undercut works in conjunction with the other ergonomic improvements to give you better leverage and control over the firearm.

Controls and User Interface Upgrades

The Gen 6 introduces several control refinements that improve shooting performance and handling. Glock's comprehensive ambidextrous controls make the pistol functional for all shooters without requiring separate left-handed models.

Flat-Faced Trigger Design

Your Gen 6 comes with a flat-faced trigger as standard equipment. This replaces the curved trigger found on previous generations. The flat-face trigger provides a more consistent finger placement and contact point during each press.

The trigger maintains Glock's Safe Action system with a 5.5-pound pull weight. This gives you the same reliable trigger safety mechanism that Glock has used for years. The flat design helps improve trigger control, especially during rapid fire sequences.

Many shooters previously bought aftermarket flat triggers for their Glocks. Now you get this feature from the factory without additional modifications or expenses.

Slide Stop Lever Redesign

The slide stop lever on your Gen 6 features deeper serrations for better grip. These improved slide serrations help you manipulate the slide in both wet and dry conditions.

The control layout remains similar to Gen 5 models. This means you can transition to Gen 6 without relearning your manual of arms. The serrations appear on both the front and rear of the slide, giving you multiple grip options during loading and malfunction clearing.

Thumb Rest and Gas Pedal

Your Gen 6 includes ambidextrous gas pedals with RTF6 texturing from the factory. These thumb rests provide additional grip stability and control during shooting. The RTF6 texture combines elements from RTF2 and RTF-4 patterns.

The gas pedals extend higher on the frame compared to previous generations. This gives you more surface area for your support hand thumb. The texture helps lock your hands in place during recoil.

Both left and right-handed shooters can use these controls equally. You don't need to buy separate parts or make modifications for your shooting preference.

Magazine Release and Takedown Lever

The magazine release maintains its reversible design for ambidextrous use. You can swap it to either side of the frame based on your needs. The button is easily accessible without requiring you to shift your firing grip.

The takedown lever keeps the same basic operation as Gen 5 models. You pull it down during disassembly after removing the magazine and clearing the chamber. The control doesn't protrude excessively from the frame, which prevents accidental activation during holstering or handling.

Gen 6 Optic Ready System and Slide Features

Glock replaced its MOS system with a new Optic Ready System that allows optics to mount lower and more securely. The slide also received deeper serrations, a sealed extractor channel, and a redesigned backplate.

Design Shift from MOS to Optic Ready System

The Gen6 optic ready system represents the biggest change in this generation. Glock removed the traditional MOS system that shooters criticized for raising optics too high above the bore axis. The new system lets red-dot optics sit deeper in the slide cut.

This design reduces height over bore, which improves your accuracy by minimizing mechanical offset. When your optic sits closer to the barrel, you get a more natural sight picture and better alignment with the bore axis.

All Gen 6 models ship optics-ready from the factory. You don't need to buy a separate MOS version anymore. The new optic cut design changes how you mount and configure your slide for red-dot use.

Optic Plates, Bosses, and Compatibility

Your Gen 6 pistol includes three polymer optic plates in the box. These plates work with RMR, DeltaPoint Pro, and Holosun K footprints. The plates compress during installation to create friction between the plate, optic, and slide.

This friction-fit design acts as a shock absorber. It protects your optic from the forces generated during slide cycling. The system also supports direct-mount capability, letting you attach optics straight to the slide without a plate.

Direct mounting reduces failure points that can occur with traditional plate systems. You can mount popular optics like the Trijicon RMR, Aimpoint ACRO, and Holosun 509T using the included plates or direct-mount interface. The refined mounting system provides better optic retention than previous generations.

Slide Serrations Redesign

The Gen 6 features deeper front and rear slide serrations. These cuts extend further into the slide surface than Gen 5 models. The enhanced serrations give you better purchase when manipulating the slide.

You'll notice improved grip in both wet and dry conditions. The deeper cuts make press checks easier and help during malfunction clearing. The serrations work together with other grip enhancements to give you more control points on the pistol.

Extractor Channel and Backplate Changes

Glock sealed the extractor channel on Gen 6 slides. This prevents threadlocker from migrating into the extractor depressor plunger area when you mount an optic. The sealed design protects internal components from contamination.

The Gen 6 backplate uses a narrower design with different geometry than previous generations. You cannot swap Gen 5 backplates onto Gen 6 slides. These changes improve the slide's structural integrity around the optic mounting area while maintaining reliability.

Performance, Reliability, and Range Experience

The Gen 6 models maintain Glock's reputation for dependable function while introducing internal updates and improved shooting characteristics. Early testing reveals compatibility with existing gear and notable improvements in how the pistol handles during extended use.

Internal Mechanisms and Recoil System

The Gen 6 features a redesigned internal structure while retaining some legacy parts. The locking block carries over from previous generations, ensuring proven reliability in the barrel lockup system. The recoil spring assembly also remains compatible with earlier models, which means you can use replacement parts you may already have on hand.

Most internal components are new to Gen 6. The new generation includes an updated striker, extractor, and trigger mechanism that require different installation procedures compared to Gen 1-4 models. Glock's training division now offers separate armorer courses for Gen 5-6 versus classic models due to these internal changes.

The recoil system continues to use Glock's dual spring design. This setup helps manage muzzle flip and keeps the pistol flatter during rapid fire strings.

Accuracy and Shootability Enhancements

The Gen 6 delivers improved accuracy and ergonomic upgrades that make the pistol easier to shoot well. The new flat-faced trigger offers a more consistent break compared to previous generations. You'll notice the trigger pulls more cleanly without the curved face that characterized earlier Glocks.

The redesigned grip texture and improved ergonomics help you maintain better control during recoil. These upgrades represent a significant evolution rather than a minor refresh. Your hand positions more naturally on the frame, which translates to better shot placement.

The direct-milled optics mounting system enhances accuracy potential. You can mount red dot sights lower to the slide, which creates a better sight picture and reduces the added height that older MOS systems introduced.

Holster and Magazine Compatibility

The Gen 6 fits holsters designed for earlier Glock generations. The external dimensions remain consistent with Gen 5 models, so you don't need to replace your existing holster collection. This backward compatibility extends across duty holsters, concealment rigs, and competition setups.

Legacy magazines work perfectly in Gen 6 pistols. You can use Gen 3, Gen 4, and Gen 5 magazines interchangeably without any function issues. This compatibility saves you money and ensures you can continue using your current magazine inventory.

The backstraps also carry over from previous generations. If you have spare backstraps from a Gen 5, they'll install directly on your Gen 6 frame.

Range Feedback and Endurance

Range testing confirms the Gen 6 performs reliably through extended shooting sessions. Reviewers who put hundreds of rounds through test guns reported zero malfunctions during initial evaluation periods.

The improved ergonomics become more noticeable during longer range sessions. You'll experience less fatigue in your grip hand thanks to the revised frame contours. The better trigger also helps maintain consistent accuracy as round counts climb.

Testing over 500 rounds demonstrated the pistol's reliability and the practical benefits of the ergonomic updates. The gun stays comfortable even when you're running multiple magazine changes and sustained fire drills. Your groups tend to stay tighter compared to earlier generations because the improved grip helps you manage recoil more effectively.

Gen 6 Versus Previous Glock Generations

The Gen 6 marks the most significant design evolution in Glock's history, with changes that go beyond the incremental updates of previous generations. While Gen 5 brought refinements like ambidextrous controls and the Marksman Barrel, Gen 6 introduces standard optics-ready slides, enhanced ergonomics, and improved triggers that set it apart from all earlier models.

Comparison with Gen 5 and Gen V Series

When you compare the Gen 6 to Gen 5 models, the most obvious difference is the standard optics-ready slide. Every Gen 6 comes with what Glock calls MOS 2.0, while Gen 5 required you to purchase a separate MOS variant at a premium price. The Gen 6 trigger system delivers a lighter pull weight averaging 4.5-5 pounds compared to Gen 5's 5.5-6 pounds.

The grip texture on Gen 6 is more aggressive than Gen 5's relatively mild texturing. You'll notice better purchase during recoil, especially with wet or sweaty hands. Gen 6 also features a true ambidextrous magazine release, while Gen 5 only offered bilateral slide stops.

The Gen V Series differs from standard Gen 5 in that it includes factory customization options. However, Gen 6 incorporates many features that previously required custom work, making the distinction less relevant.

Backward Compatibility and Legacy Parts

Your Gen 6 Glock maintains compatibility with most Glock parts from previous generations. Legacy magazines from Gen 3, 4, and 5 will function in Gen 6 pistols, though the new Gen 6 magazines offer improved feed lip geometry and follower design.

Gen 6 pistols accept older generation sights, triggers, and internal parts like springs and connectors. You can use Gen 5 barrels in Gen 6 frames, though the Gen 6 barrel offers tighter tolerances. Holster compatibility varies depending on whether you mount a red dot sight, since the optics-ready slide adds height.

Most aftermarket accessories designed for Gen 5 will work with Gen 6, including weapon lights that attach to the accessory rail.

Visual and Functional Differences

You can identify a Gen 6 by looking at the enhanced slide serrations that cover more surface area than previous Glock generations. The slide features front and rear serrations as standard, plus shallow top serrations that reduce glare.

The grip texture appears more pronounced with strategic placement of aggressive zones. Gen 6 frames have a more defined beavertail and undercut trigger guard compared to the subtle contours of Gen 5. The optics cut on top of the slide is the clearest visual indicator, even without a red dot mounted.

When you handle Gen 6 versus earlier generations, you'll notice the improved recoil impulse from the refined spring assembly and the crisper trigger break with shorter reset.
