Verdict Summary
After handling more Glocks than I can count, the Gen5 17 is the one I’d grab for a long day at the range or a serious defensive role. It’s not about flashy features; it’s about the quiet confidence that comes from a tool engineered to work, every single time. The refinements in the frame and barrel are meaningful, not just marketing. For $429, you’re getting the most evolved version of the pistol that defined modern polymer handguns.
Key Features & What Sets It Apart
This isn’t just another Glock. The Gen5 series incorporated direct feedback from high-volume users. Here’s what that means for you.
- The Gen5 Frame: They removed the finger grooves. This single change opens up the Glock 17 Gen5 to a wider range of hand sizes and allows for a more natural, high grip. The frame has a slightly more aggressive texture in the right places, and the flared magwell makes reloads smoother under pressure.
- Glock Marksman Barrel (GMB): This is a serious upgrade. The rifling and crown are redesigned for improved accuracy. In my testing, it consistently tightens groups compared to older generations. It’s a cold-hammer-forged barrel built for a long service life.
- Ambidextrous Slide Stop Levers: Finally, a true ambi control. Whether you’re a lefty or doing malfunction drills, having a lever on both sides is a genuine operational improvement.
- nDLC Finish: The slide wears a tougher, more corrosion-resistant finish. It stands up to holster wear better than the previous finish and has a uniform matte look.
- No Half-Moon Cutout: The front of the Glock 17 Gen5 frame no longer has the cutout that some found irritating. It’s a cleaner, more comfortable grip.

Pros & Cons: An Honest Assessment
Pros:
- ✅ Unmatched reliability and simplicity. It goes bang.
- ✅ The Glock 17 Gen5 frame improvements are significant for grip and control.
- ✅ Marksman Barrel provides a measurable accuracy boost.
- ✅ Massive aftermarket. Want a Glock 17 Gen5 threaded barrel or Glock 17 Gen5 MOS optic cut? Easy.
- ✅ Ambi controls make it truly universal.
- ✅ Proven track record with military and law enforcement worldwide.
Cons:
- ❌ The trigger. It’s a Glock trigger—consistent but spongy. Serious shooters will upgrade it. See our trigger parts.
- ❌ No optics cut from the factory on this model. If you need a red dot, you’ll need to mill the slide or buy a separate Glock 17 Gen5 MOS model. We offer slide milling services.
- ❌ Stock sights are plastic. They work, but they’re the first thing most folks replace.
Who Should (and Shouldn’t) Buy the Glock 17 Gen5
Buy it if: You need a dependable, no-fuss defensive or duty pistol. You’re a first-time handgun owner who values reliability above all. You’re a seasoned shooter who appreciates a proven platform with endless customization options. You want a full-size 9mm that can handle thousands of rounds of practice without complaint.
Skip it if: You must have an optics-ready pistol out of the box. (Look at the Glock 17 Gen5 MOS). You’re solely a concealed carrier and find full-size guns too large. (Consider the Glock 19). You’re a collector only interested in classic steel. This is a working man’s tool.
Frequently Asked Questions
How do I disassemble a Glock 17 Gen 5?
Clear the pistol. Pull the trigger to decock (ensure it’s empty!). Pull down slightly on the two slide lock tabs on the frame, then push the slide forward off the frame. Remove the recoil spring assembly and barrel from the slide. That’s field-stripping for cleaning. No tools needed.
How do I break down a Glock 17 Gen 5 for cleaning?
“Break down” typically means field-stripping, as described above. For a complete detail strip (not recommended for routine cleaning), you’ll need punches to drive out pins. Stick with field-stripping for 99% of maintenance. The manual has full instructions.
How can I tell what generation my Glock 17 is?
Check the frame. Gen5 has no finger grooves, ambidextrous slide stops, and a flared magwell. The slide will have “Gen5” marked on it. The serial number prefix can also indicate generation, but the physical features are the fastest tell.
Is the Glock 17 Gen 5 good?
It’s not just good; it’s the benchmark. The improvements in ergonomics and barrel accuracy address the main critiques of earlier models while retaining the legendary reliability. For a duty-size 9mm, it’s the standard against which others are measured.
What’s the difference between the Glock 17 Gen5 and the MOS version?
Can I use my old Glock 17 magazines in a Gen5?
Gen5 magazines are optimized for the flared magwell and have an orange follower. Older Gen1-4 magazines will physically fit and function, but for optimal reliability, especially in defensive use, Gen5 mags are recommended.

Did a lot of research before pulling the trigger on this purchase (pun intended).

Been in the market for a while and finally decided to buy from glockswitchstore.com. I was comparing this against similar products from the other site and decided to take the chance. Glad I did. Arrived in 4 days, well-packaged, and the quality speaks for itself. Installed it on my Glock 45 and ran 139 rounds through it without a single hiccup. This is the real deal.
