Many gun companies love to slap “new model” on a firearm after tweaking a tiny feature or two. Honestly, that’s exactly what I would have expected Glock to do with the Gen6 lineup. No knock on them, it just seems all too common these days. Thankfully, I would have been entirely wrong, and I’m more than happy to admit it.

Aesthetics have improved with the new frame.

Earlier this week, I was invited to Glock’s U.S. headquarters for an early look at the Gen6 pistols. This wasn’t a quick walk-through or a surface-level media demo. We were able to shoot the guns (with unlimited ammo, no less), tear them down, and even get a behind-the-scenes look at parts of the manufacturing process.

Of course, we had to confirm they take the same mags as Gen5!

After spending time on the range with all three new models, it became clear fast: this isn’t a minor refresh dressed up as a “new generation.” The Gen6 pistols represent a meaningful leap forward.

Upgraded Features

While the G17, G19, and G45 differ slightly in size, they all share the same set of upgraded features. Here’s what stood out.

Gen6 Optic-Ready System

Glock’s new system focuses on increased direct-mount compatibility. Instead of your optic securing to a plate that then secures to the slide, this design allows the optic to secure directly to the slide itself. The included polymer plates act more like crush washers than mounting plates.

The new and improved mounting system.

The benefit? A noticeably lower deck height and reduced vibration or shifting under recoil. Each pistol ships with three optic plates that cover the most popular footprints, giving you plenty of flexibility.

Factory Flat Trigger

If you know Glock shooters, you know plenty who’ve swapped to aftermarket flat triggers. You might even be one of them. Now, Glock finally offers a flat trigger straight from the factory.

Curves and lack of curves in all the right places.

The pull is smooth, the break is clean, and the reset is short, and if you look closely, there’s even a new undercut beneath the trigger guard. Paired with the larger beavertail, it really helps you lock in a high, solid grip.

Overhauled Ergonomics

A lot of effort went into the ergonomics this time around. The most noticeable change is the new, aggressive grip texture. It uses two patterns to strike a balance between secure purchase and not being overly grabby on your clothing.

You won’t have to worry about wet or sweaty hands.

The grip also features a well-shaped palmswell that larger-handed shooters will appreciate, along with a subtly flared magwell for smoother reloads. Glock includes two interchangeable backstraps to help fine-tune your fit as well.

Do yourself a favor and try each one out.

One of the most surprising additions is the ambidextrous thumb rest (gas pedal) molded directly into both sides of the frame. During rapid strings of fire, you can absolutely feel the added control. And because it’s cut into the frame rather than protruding, your existing holsters should still work.

Range Time

Unlimited ammo and people loading mags for you? Yeah, I wasn’t shy about taking advantage and putting as many mags down range as possible in the allowed time.

The new Glocks paired with Trijicons were a great combo.

After burning through dozens of magazines across all three models, the consensus was consistent: the upgraded ergonomics and flat trigger noticeably help the Gen6 pistols run flatter and smoother. Follow-up shots stayed tight, and the recoil was very easily controlled.

Pros & Cons

Pros:

  • Lower, more adaptable optic cut
  • Very smooth and clean flat trigger
  • Aggressive texturing with additional index points
  • Enlarged beavertail and improved slide-stop protection
  • Palmswell works especially well for large hands
  • Most existing holsters should still fit

Cons:

  • Some shooters may find the texture a bit too aggressive

Final Thoughts

Without diving into every incremental generational difference, I’m confident in saying the upgrade to the Gen6 is worth it. The trigger, optics system, and ergonomics come together to provide a nice balance of performance and versatility.

Am I ditching our older Glocks? Absolutely not. But will I be adding a Gen6 or two to the rotation? Without question.

As always, stay safe, train hard, and have fun.
