How to Choose the Right Glock Slide
Four quick checks make sure your new Glock slide fits your frame and does the job you want it to do.
Match Your Model
A Glock 19 slide is built for a Glock 19 frame, a Glock 17 slide for a Glock 17. Start with the model number stamped on your pistol.
Check the Generation
Gen 4 and Gen 5 slides are marked on the side; Gen 3 slides have no marking. Gen 4 and Gen 5 use a dual recoil spring, Gen 3 a single spring — so generation matters.
Stripped or Complete
A stripped slide is the bare slide. A complete slide comes assembled with its internal parts, ready to install. Choose based on the parts you already have — see the comparison below.
Optics or Iron Sights
Running a red dot? A MOS (Modular Optic System) slide has a factory optic cut. Iron-sight slides suit shooters who don't plan to mount an optic.

What Our Customers Say
What buyers have told us about their Glock slide orders.
“Was a little nervous dropping this much on a slide online but it showed up fast and looks awesome. Fit my gen 3 19 frame perfectly. The black finish matches my lower exactly. Good stuff.”
“Finally got to the range with the 43x slide I got from you guys. Put 200 rounds through it with zero hiccups. The optic cut was perfect for my Holosun. Thanks for the fast shipping.”
“Slide is legit OEM, no issues with the internals. Only giving 4 stars because it took a couple days longer to ship than I thought it would, but the tracking updated eventually and the product is solid. Can't beat the price for a complete slide.”
“Ordered the Glock 17 MOS slide. Came in a few days. Everything looks factory new. Dropped right on. Will definitely be checking back here for my next build.”
“Great customer service. I had a question about the difference between the stripped and complete and they got back to me quick. Slide works great.”
Glock Slide FAQ
Answers to the questions we hear most about buying Glock slides online.
Are your Glock slides genuine OEM?
We carry both. Every listing states whether it is an OEM Glock slide (made by Glock) or an aftermarket slide like our Zaffiri Precision slides, so you always know exactly what you are buying.
Will a Glock 19 slide fit my frame?
A Glock slide is designed for its matching model and generation — a Glock 19 Gen 3 slide for a Glock 19 Gen 3 frame, for example. Some slides cross over between generations depending on the frame and recoil spring assembly. If you are unsure, send us your model and generation and we will confirm fitment.
What is the difference between a stripped and a complete slide?
A stripped slide is the bare slide without internal parts. A complete slide comes assembled with its internal parts and installs on a compatible frame as one unit. Builders reusing parts often choose stripped; most replacements are complete. Compare them side by side.
What does MOS mean on a Glock slide?
MOS stands for Modular Optic System. A MOS slide has a factory optic cut and uses adapter plates so you can mount a red dot sight without having the slide milled. Popular options include the Glock 19 Gen 5 MOS and Glock 19X MOS slides.
How do I tell which generation my Glock is?
Gen 4 and Gen 5 Glocks are marked "Gen4" or "Gen5" on the slide. Gen 3 slides have no generation marking. Gen 4 and Gen 5 pistols also use a dual recoil spring assembly, while Gen 3 uses a single spring.
Do you offer free shipping on Glock slides?
Yes. Orders over $350 ship free, and every order includes tracking. Shipping details are in our Help Center.
Is it legal to buy a Glock slide online?
Under US federal law the frame, not the slide, is the regulated part of a pistol. Some states and cities have their own rules, so please check the laws where you live before ordering. Buyers are responsible for complying with all federal, state and local laws. See our Terms & Conditions.
