A new slide is one of the easiest ways to refresh your Glock. For example, you can add a red dot, swap to a longer sight radius, or simply replace a worn upper. Best of all, the frame you already know stays exactly the same.

Gen 3 vs Gen 4 vs Gen 5 Glock Slides
In short, a slide must match both your model and your generation. Here is how to tell them apart, so you buy the right one the first time.
The Classic
- Rear slide serrations only
- Tenifer-style matte finish
- Single recoil spring
- No "Gen" marking on the slide
The Upgrade
- Rear serrations, larger magazine catch
- Dual recoil spring
- "Gen4" stamped on the slide
- MOS optic-ready versions available
The Latest
- Front and rear serrations
- nDLC finish and Marksman barrel
- "Gen5" stamped on the slide
- Most models offered as MOS
First, look at the left side of your slide. Glock stamps "Gen4" or "Gen5" next to the model number on newer slides, while Gen 3 slides have no Gen marking. Still unsure? Then ask our team before you order, and we'll confirm the right slide for you.
DIY · Fit it at homeMost Owners Fit Their Slide at Home

Stripped Slide
Basically, the slide itself, ready for you to build with your own parts.
- Factory front and rear sights included
- Use your own barrel, spring and internals
- The lower-cost way to upgrade
- Great for custom builds and spares
Complete Slide Assembly
By contrast, a fully assembled upper, ready to fit straight onto a matching frame.
- Barrel, recoil spring and internals installed
- Factory steel white-dot sights
- Fits a matching model and generation frame
- No gunsmith needed for a matching frame
MOS Optic-Ready Glock Slides
In particular, MOS (Modular Optic System) slides come cut from the factory for a red dot sight. As a result, you can mount an optic without sending your slide off for milling. For example, popular optics our customers run include:
Currently, we offer MOS slides for the Glock 17, Glock 19, Glock 19X, Glock 22, Glock 26 and Glock 34. Some optics need a specific adapter plate, so check your optic's footprint before you order.

Matt P.How to Choose the Right Glock Slide
Overall, buying Glock slides online is simple once you know three things: your model, your generation and the option you want. With this in mind, here is a quick guide to getting it right.
1. Start with your model number
Glock stamps your model number on the left side of the slide and on the frame, for example "17", "19" or "43". Because each model has its own length and width, a Glock 19 slide will not fit a Glock 17 frame, and so on. In addition, caliber matters: a Glock 22 is the .40 S&W version of the 9mm Glock 17, while the Glock 23 pairs with the Glock 19. So always shop by your exact model.
2. Match your generation
Next, check whether your pistol is a Gen 3, Gen 4 or Gen 5. Generations differ in recoil springs, slide stops and internal parts. Therefore, the safest choice is always a slide from the same generation as your frame. Gen 5 slides, for example, have front serrations and a "Gen5" stamp, whereas Gen 3 slides have rear serrations only and no Gen stamp.
3. Decide on stripped or complete
A stripped slide is the shell with sights, so you move your own barrel and internals across. A complete assembly, on the other hand, arrives fully built and ready to fit. If you want the easiest upgrade, a complete slide is usually the better choice.
4. Think about optics
If you plan to run a red dot now or later, choose a MOS slide. MOS slides come cut from the factory, so you avoid the cost and wait of custom milling. Meanwhile, standard slides keep a slimmer profile for iron-sight shooters.
5. Check your holster
Generally, a slide of the same model and generation fits the same holster. However, an optic-ready slide with a red dot mounted needs an optic-cut holster. Likewise, longer slides such as the Glock 34 need a holster made for that length.
Still unsure? Then contact our team, tell us your model and generation, and we'll point you to the right slide. You can also browse the full Glock slide shop or learn more about us.
Glock Slide FAQs
Here are quick answers to the questions we hear most. For anything else, however, visit Customer Help.
Will a Gen 3 slide work on a Gen 4 or Gen 5 frame?
Not reliably, because generations use different recoil springs and internal parts, so we always recommend matching your slide's generation to your frame's generation. If you want to mix generations, contact us first and we'll tell you what's needed.
What's the difference between a stripped and complete slide?
A stripped slide is the slide with factory sights, ready for your own barrel and internals. In contrast, a complete slide assembly comes fully built, with barrel, recoil spring and internals installed, so it's ready to fit a matching frame.
Can I install a Glock slide myself?
Yes, in most cases. For instance, a complete slide for the same model and generation goes on just like reassembling your pistol after cleaning. Meanwhile, a stripped slide needs your parts moved across, which many owners do at home. However, if you're unsure, a gunsmith can do it quickly.
How can I tell which generation my Glock is?
First, check the left side of your slide. Newer slides carry a "Gen4" or "Gen5" stamp, whereas Gen 3 has no Gen marking. In addition, Gen 5 frames have no finger grooves, and Gen 5 slides have front serrations.
Do your slides come with sights?
Yes. Complete slide assemblies include factory steel white-dot sights, and stripped slides also include factory front and rear sights. In addition, we offer night sights as an upgrade on request.
Are these slides compatible with my holster?
Generally, a slide of the same model and generation fits the same holster. However, a MOS slide with an optic mounted needs an optic-cut holster.
How do I pay?
Simply place your order with no card details. Then we email you payment details for Zelle, Chime, Cash App, Apple Pay, PayPal, Interac or bank transfer. As soon as we confirm your payment, we ship with tracking.
What is your return policy?
Every order comes with a 30-day money-back guarantee. So if your slide isn't right, contact us within 30 days and we'll help you return it.
