Overview of Glock Gen 6

Glock officially announced the Gen 6 pistol line on December 6, 2025, introducing improvements to ergonomics, optics mounting, and trigger design across three initial 9mm models. The 6th generation of Glock pistols maintains the company's approach of evolutionary rather than revolutionary changes.

Release Timeline and Availability

The Glock Gen6 will become commercially available starting January 20, 2026. The public debut is scheduled for SHOT Show 2026 in Las Vegas.

Glock took approximately five years to develop the Gen 6. The project involved collaboration between Glock's operations in Smyrna, Georgia and the company's facilities in Austria.

The initial release includes three models: the G17 Gen 6, G19 Gen 6, and G45 Gen 6. All three are chambered in 9x19mm. A fourth model, the G49, was shown at the announcement event but will not be released in the U.S. market. Additional models may be introduced based on market response.

Notable Differences from Previous Generations

The Gen 6 frame features a slimmer grip profile compared to Gen 5. The grip includes a subtle taper in the thumb rest area, which Glock calls a palm swell.

A new RTF6 (Rough Textured Frame) pattern replaces previous texturing. This design balances grip security in wet or dirty conditions with reduced abrasion to clothing and skin. It serves as a middle ground between the aggressive RTF2 pyramid pattern and the smoother Gen 4 and Gen 5 textures.

Factory-molded beaver tail integration prevents slide contact with the shooter's hand. The trigger guard includes a factory undercut for a higher grip position. An ambidextrous textured thumb rest provides additional leverage for the support hand.

The barrel design has changed and will not be compatible with previous generations. Internal slide geometry has been redesigned with raised ridges in the firing pin channel and a modified locking block shape.

Standard Features Across All Models

All Gen 6 models come standard with a flat-faced trigger shoe that maintains Glock's Safe Action System. The trigger sits closer to the grip, reducing trigger travel.

The new Optic Ready System (ORS) replaces the previous MOS mounting system. ORS uses polymer shims instead of metal adapter plates. The optic mounts directly to the polymer base, eliminating issues with screws interfering with the extractor. Three shims are included: RMR, DPP, and C-More footprints. ACRO compatibility is in development.

Vertical serrations appear on both front and rear slide surfaces. These cuts are tapered, with deeper cuts at the top and shallower cuts toward the bottom. Glock returned to a single captive recoil spring system after using dual spring assemblies in Gen 4 and Gen 5.

Despite frame modifications, Gen 6 pistols maintain full compatibility with existing Gen 5 holsters.

Key Innovations and Features

The Glock Gen 6 brings substantial upgrades focused on ergonomics, trigger mechanics, and optics mounting. These changes address feedback from shooters while maintaining compatibility with existing Gen 5 holsters.

Enhanced Ergonomics and Grip Design

The Gen 6 frame features a redesigned grip profile that's less bulky than the Gen 5. A subtle palm swell in the thumb rest area improves fit for shooters with smaller hands and provides better control when wearing gloves.

Glock introduced the RTF6 texture (Rough Textured Frame) across the grip surface. This new pattern balances aggressive grip in wet or dirty conditions with reduced abrasion to clothing and skin. It's less aggressive than the older RTF2 pyramid pattern but grippier than Gen 4 and 5 textures.

A factory-molded beavertail comes standard on the frame to enhance control and prevent slide contact with the shooter's hand. The Gen 6 includes a factory undercut of the trigger guard, allowing a higher grip on the pistol. This modification was previously only available through custom shops.

Ambidextrous textured thumb rests provide an additional leverage point for the support hand's thumb. A fence below the slide stop lever prevents accidental activation when gripping the pistol high. Multiple backstraps are included to adjust trigger reach.

Flat-Faced Trigger and Improved Trigger Pull

All Gen 6 models come standard with a flat-faced trigger shoe that maintains the Safe Action System. The flat geometry supports more intuitive finger placement compared to the curved triggers on previous generations.

The trigger sits closer to the grip, resulting in slightly reduced trigger travel. This positioning helps shooters maintain better control during rapid fire. The trigger pull remains consistent with Glock's safety standards while offering improved feel and responsiveness.

Optics Mounting System and Optic Plates

The Gen 6 replaces the MOS system with the new Optic Ready System (ORS). Instead of metal adapter plates, ORS uses polymer shims inserted into the slide cut. The optic mounts directly to this base, simplifying installation.

This design eliminates the issue of long screws interfering with the extractor mechanism that plagued some MOS configurations. The polymer shim acts as a crush-washer to absorb and dampen recoil energy directed at the red dot sight.

Three shims come with each pistol covering RMR, DPP, and C-More footprints. An ACRO attachment system is under development. All Gen 6 slides come factory ready for optics mounting.

Upgraded Slide Serrations and Slide Stop Lever

Vertical serrations appear on both front and rear of the slide for positive manipulation during reloading or chamber checks. Unlike Gen 5, these cuts are tapered—deeper on the upper portion and shallower toward the bottom.

The tapered design provides better purchase for gross motor movements while reducing snag points. Combined with the slide stop lever fence, these updates improve weapon handling under stress without compromising the pistol's profile or holster compatibility.

Glock Gen 6 Models and Specifications

Glock launched three Gen 6 models on December 6, 2025, all chambered in 9mm Luger. The G17 Gen6, G19 Gen6, and G45 Gen6 share the same core improvements but serve different roles based on size and capacity.

Glock 17 Gen6

The Glock 17 Gen6 maintains its position as Glock's full-size duty pistol. It features a 4.49-inch barrel and a standard 17-round magazine capacity.

The Gen 6 update brings several improvements to the G17 platform. The ergonomic frame includes a palm swell, extended thumb rest, and enlarged beavertail. These features work together to provide a more secure grip during shooting.

The slide includes deeper angled serrations for better manipulation. The flat-faced trigger comes standard and maintains the Safe Action System. An undercut trigger guard allows shooters to achieve a higher grip on the frame.

The optics-ready system includes three mounting plates that allow direct mounting of various red dot sights without an adapter plate. The dual-texture grip covers more surface area than previous generations.

Glock 19 Gen6

The Glock 19 Gen6 is a compact model that fits between the full-size G17 and subcompact options. It has a 4.02-inch barrel and holds 15 rounds in the standard magazine.

The G19 receives all the same Gen 6 improvements as the G17. The palm swell, extended thumb rest, and enlarged beavertail create an ergonomic package in a smaller frame. This makes it popular for both duty use and concealed carry.

The compact size makes the G19 Gen6 easier to conceal than the full-size G17 while still providing a full grip for most shooters. The reduced distance from the frame to the trigger helps accommodate different hand sizes.

Like other Gen 6 models, it comes with the new optics mounting system and three plates. The MSRP matches Gen 5 pricing at approximately $650.

Glock 45 Gen6

The Glock 45 Gen6 combines a compact slide with a full-size frame. It uses the shorter 4.02-inch barrel from the G19 with the full-length grip of the G17, resulting in a 17-round capacity.

This configuration creates a duty pistol that offers full magazine capacity with a shorter overall length. The full-size frame provides the same ergonomic improvements as the G17 Gen6. The compact slide reduces the overall length by about half an inch compared to the G17.

Law enforcement agencies often prefer this setup because it provides full capacity without the extra slide length. The shorter slide can make the pistol easier to draw from a holster while maintaining shootability.

All three Gen 6 models will be available on shelves January 20, 2026. They share the same parts compatibility within the Gen 6 line for magazines and accessories.

Practical Applications and User Considerations

The Glock Gen 6 introduces targeted improvements that affect how shooters use these pistols in different scenarios. The enhanced ergonomics and modular features address specific needs across carrying, professional duty use, and competitive shooting.
