OEM Upper Slides

General Product Questions

Below are some of are common questions about our products

Are these actually made by Glock and SIG Sauer?

Yes. We sell only 100% authentic, Original Equipment Manufacturer (OEM) factory parts. We do not sell “OEM-style,” “clones,” or “high-end replicas.” If it says Glock or SIG on our site, it came from their factory.

We offer both.

  • Complete: Includes the firing pin/striker assembly, extractor, safety plunger, and factory sights.

  • Stripped: The bare slide only. Please read the product description carefully to see exactly what is included with your specific selection.

Our inventory comes from several professional sources, including factory-direct overstock and brand-new “take-offs” from new, unfired firearms.

 

Compatibility & Technical

Below are some common questions about product, and compatibility. 

Will a Gen 5 Glock slide fit my Gen 3 frame?

Generally, no. Glock generations have different internal dimensions and slide-stop configurations. We highly recommend matching your slide generation to your frame generation.

 

Yes! Genuine OEM slides are the preferred choice for high-end custom builds (like Polymer80 or SCT frames) because they provide the most reliable baseline for troubleshooting and performance.

 

Unless specifically listed as a “Full Exchange Kit” or “Complete Upper Kit,” our slides do not include the barrel or recoil spring assembly.

 

Shipping & Legal

Below are some of are common questions about Shipping & Legal status

Do I need an FFL (Federal Firearms License) to buy a slide?

No. In the United States, the “firearm” is the serialized frame (Glock) or the Fire Control Unit (SIG). Since the slide is considered a “part,” it can be shipped directly to your front door. No FFL transfer is required.

 

Yes. Currently, there are no federal restrictions on shipping non-serialized slide assemblies to these states. However, it is always your responsibility to ensure your finished build complies with all local and state laws.

 

All orders over $300 are shipped with insurance and may require a signature upon delivery to ensure your package arrives safely and is not left unattended.
