What Is Different About the New Glock Gen 6: Key Upgrades Explained

If you’ve carried a Glock for any amount of time, you probably know the feeling. It works. It always works. But you also know the little things you would tweak if Glock ever decided to listen. Maybe it’s the grip texture. Maybe it’s the trigger face. Maybe it’s the optic sitting just a little too high. The Gen 6 feels like Glock finally paying attention to those conversations shooters have been having for years. It is not a reinvention of the wheel. It is refinement where it actually matters.

Glock released its sixth generation of pistols, focusing on three popular models: the G17, G19, and G45. The Gen 6 brings redesigned ergonomics including new grip texture called RTF6, a flat-faced trigger, improved optics mounting, enlarged beavertail, and updated controls while keeping the reliability Glock is known for. These changes represent what Glock describes as "Ergonomics Redefined" rather than just small tweaks to the previous generation.

The updates target real-world use for concealed carry, home defense, and duty applications. You'll notice the differences as soon as you pick one up, from the way the grip feels in your hand to how the controls fall under your fingers. The new RTF6 texture provides more coverage including areas like the thumb rest, giving you better grip without being too rough on your skin or clothing.

Whether you currently own an earlier Glock or you're considering your first purchase, understanding what changed in Gen 6 helps you make an informed decision. The improvements focus on making the pistols easier to shoot well, faster to get on target, and more compatible with modern accessories like red dot sights.

Key Takeaways

• Gen 6 features redesigned grip texture, a flat trigger face, and an improved optics-ready system across the G17, G19, and G45 models

• The ergonomic changes include better grip contouring, enlarged beavertail, and updated controls that improve handling and reduce fatigue

Core Changes in Glock Gen 6 Pistols

The Gen 6 pistols represent Glock's most significant platform update in years, featuring redesigned ergonomics, a new trigger system, and enhanced optics compatibility across the initial three-model lineup.

How Gen 6 Differs from Gen 5

The Gen 6 brings ergonomic advancements that set it apart from previous generations. You'll notice a palm swell that contours to your hand's natural curve, which wasn't present in Gen 5 models. The grip texture has been completely redesigned with RTF6, combining two textures to balance performance and comfort.

The beavertail has been enlarged to encourage a higher grip while ensuring smooth slide cycling. You'll find an extended, textured thumb rest that gives you more control during recoil. The trigger guard features an undercut design for improved grip support.

Glock Gen 6 pistols come standard with a flat-faced trigger instead of the curved option from Gen 5. The slide serrations are angled deeper into the slide for better tactile feedback during manipulations. The border surrounding the slide stop lever has been enlarged to prevent accidental activation.

Gen 6 G17, G19, and G45 Launch Scope

The first Gen 6 pistols released in the U.S. include the G17, G19, and G45. Glock focused this generation change on full-size and compact duty pistols rather than releasing a wide range of variants at once.

The G17 serves as the full-size option with maximum capacity. The G19 offers a compact design that balances concealability with shootability. The G45 combines the full-size grip and capacity of the G17 with the compact slide and barrel of the G19, making it an excellent carry-sized option.

Some international markets will also receive the G49 model. This tightly focused rollout centers on proven platforms that already anchor police and civilian use.

Key Internal Modifications

The new Gen 6 optics-ready system allows you to mount various optics directly to the slide. Each Glock Gen 6 pistol includes three optic plates engineered for adaptability and durability.

You receive several items with your Gen6 pistol:

• Glock Safe Action pistol with 3 magazines

• Magazine speed loader

• Cleaning set with rod, patch holder, and brush

• Instructions manual

• Pistol case for storage and transport

• Backstrap set

• 3 optic plates

The trigger maintains the Safe Action System while providing consistent finger placement. The RTF6 texture extends to new areas like the thumb rest, giving you exceptional grip confidence in any situation.

Ergonomics and Grip Improvements

The Gen 6 introduces several physical changes to how the pistol sits in your hand. Glock added palm swells, deeper undercuts, enhanced texturing, and dedicated thumb support areas to give you better control and comfort during shooting.

Palm Swell and Beavertail Enhancements

Your Gen 6 features an integrated palm swell designed to match the natural curvature of your shooting hand. This contoured shape fills the gap between your palm and the backstrap more completely than previous generations.

The enlarged beavertail sits higher on the frame to give you more contact area. This extended beavertail helps you maintain consistent grip placement each time you draw.

The combination prevents the slide from contacting your hand during recoil. You get improved control without adding bulk to the frame dimensions.

RTF6 Grip Texture and Coverage

The RTF6 grip texture combines elements from earlier Glock texturing patterns to create a more aggressive surface. You'll find this new texture covers more of the frame than Gen 5 models.

Key RTF6 coverage areas:

• Front strap extending higher toward the trigger guard

• Side panels reaching further up the grip

• Thumb rest areas on both sides

• Backstrap from bottom to top

The texture extends into areas that were previously smooth. This gives you better traction in wet conditions or when wearing gloves.

Undercut Trigger Guard for Higher Grip

Glock deepened the trigger guard undercut on Gen 6 models to let your hand sit closer to the bore axis. This undercut removes material where your middle finger meets the frame.

A higher grip reduces muzzle rise during rapid fire. You maintain better sight alignment between shots because the pistol pivots less in your hand.

The deeper undercut also improves your finger placement on the trigger. Your trigger finger reaches the face at a more natural angle without requiring you to adjust your grip.

Thumb Rest and Support Hand Control

Gen 6 pistols include ambidextrous gas pedals with RTF6 texturing as standard equipment. These raised thumb rests give your support hand a defined point of contact.

The textured surface on each thumb rest prevents your hand from slipping forward under recoil. You can apply forward pressure with your support hand thumb to help control the pistol.

These gas pedals work for both right and left-handed shooters. The symmetrical design means you don't need to swap parts based on your dominant hand.

Trigger System and Control Updates

The Gen 6 brings a factory flat-faced trigger and refinements to key controls that affect how you interact with the pistol during shooting and manipulation.

Flat-Faced Trigger Design

Glock replaced the curved trigger with a flat-faced design in the Gen 6. The trigger still uses Glock's Safe Action System but now provides more consistent finger placement across different hand sizes.

The flat face gives you a more intuitive trigger pull. Your trigger finger makes contact at the same point every time, which helps with accuracy and repeatability.

The Gen 6 trigger approaches the quality of aftermarket upgrades that typically cost $100-200. The trigger pull weight remains at 5.5 pounds, maintaining the balance between performance and safety for defensive use.

Slide Stop and Release Mechanism

The Gen 6 includes ambidextrous controls called gas pedals on both sides of the frame. These controls feature the same RTF6 texturing found on the grip.

The deeper front and rear slide serrations improve your ability to manipulate the slide in wet or dry conditions. You get better purchase when racking the slide or conducting press checks.

The slide stop is easier to engage when you need to lock the slide back manually. The enhanced serrations work together with the gas pedals to give you more control options during operation.

Enhanced Magazine Release and Controls

The Gen 6 features a redesigned flared magwell that makes magazine changes smoother. The flared opening guides magazines into the grip more easily during reloads.

The trigger guard has a deeper undercut compared to previous generations. This allows your hand to sit higher on the frame, which reduces muzzle flip and improves recoil control.

The magazine release button maintains the reversible design from Gen 5. You can swap it to either side depending on whether you shoot right or left-handed.

Slide and Optics Innovation

Glock redesigned the Gen 6 slide with deeper serrations for better grip and introduced a completely new optic mounting system that replaces the MOS platform. The Refined Optic Ready System allows optics to sit lower in the slide and comes standard on all Gen 6 models.

Deeper Slide Serrations

The Gen 6 features deeper front and rear slide serrations compared to previous generations. These enhanced serrations give you better grip during slide manipulation in both wet and dry conditions.

The improved texture makes it easier to rack the slide when your hands are sweaty or wet. You'll notice the difference immediately when performing press checks or clearing malfunctions.

The serrations work together with the new RTF6 grip texture to give you more control over the pistol. This becomes especially important during one-handed manipulations or when wearing gloves.

New Optic Ready System (ORS)

The Optic Ready System represents the biggest innovation in the Gen 6 lineup. Unlike the previous MOS system, the ORS allows your optic to sit deeper within the slide, which reduces height over bore and improves accuracy.

Your Gen 6 pistol ships optic-ready from the factory with this redesigned mounting system. The ORS features a sealed extractor design that prevents threadlocker from migrating into the extractor channel when you mount an optic.

The system supports both plate-mounted and direct-mount configurations. When you use the included polymer adapter plates, they compress during installation to create friction between the plate, optic, and slide. This friction-fit interface acts as a shock absorber that protects your optic from the forces generated during slide cycling.

You can also mount compatible optics directly to the slide without plates, which reduces potential failure points.

Adapter Plates and Mounting Footprints

Your Gen 6 includes three optic plates in the box that cover the most popular red dot footprints. These plates fit RMR, DeltaPoint Pro (DPP), and Holosun K-pattern optics.

Compatible Optic Footprints:

• RMR pattern: Trijicon RMR, Holosun 507C, Swampfox Justice

• DPP pattern: Leupold DeltaPoint Pro

• Holosun K: Holosun 407K, 507K, EPS Carry

The polymer plates are designed to compress under torque, creating a secure friction fit. This design helps absorb recoil forces and keeps your optic stable during rapid fire.

You don't need to purchase additional mounting solutions like you often did with the MOS system. The included plates cover most popular carry and duty optics right out of the box.

Compatibility and Practical Implications

The Gen 6 maintains the same external dimensions as Gen 5, which simplifies holster selection and aftermarket compatibility. The enhanced grip features and revised recoil system affect how the pistol handles during rapid fire and daily carry situations.

Gen 5 Holsters and Aftermarket Fit

You can use your existing Gen 5 holsters with Gen 6 pistols without modification. The frame dimensions remain unchanged between generations, so holster compatibility is not a concern.

The added features like ambidextrous gas pedals and deeper undercut don't extend beyond the original Gen 5 footprint. Your current Kydex, leather, or hybrid holsters will fit properly.

Aftermarket trigger upgrades and some internal parts require Gen 6-specific versions. You can reuse certain legacy components including the locking block, firing pin and spring, trigger bar, trigger pin, connector, and magazine spring. All other parts are proprietary to Gen 6.

The redesigned optic mounting system means your Gen 5 optic plates won't work. Gen 6 includes three plates for RMR, DeltaPoint Pro, and Holosun K footprints.

Home Defense and EDC Use

The enlarged beavertail and palm swell improve your grip consistency during high-stress situations. These features matter most for home defense scenarios where you may not have time to establish a perfect grip.

For EDC, the flat-face trigger with 5.5 lb pull provides better trigger control. The deeper front and rear slide serrations help when you need to press check or chamber a round with wet or sweaty hands.

The RTF6 grip texture extends higher on the frame than previous generations. This gives you more contact area without being overly aggressive against your skin during concealed carry.

Recoil Control and Muzzle Flip

The Gen 6 switches back to a single captive recoil spring system from the Gen 4-5 dual-spring design. This change affects how the slide cycles and returns to battery.

The deeper optic seating in the new Optic Ready System lowers your sight height over bore. A lower optic position reduces the mechanical offset between your bore axis and aiming point, which can improve follow-up shot speed.

The palm swell and enhanced grip texture give you better purchase during recoil. You'll notice improved control during rapid strings of fire compared to Gen 5 models with standard texturing.
