FAQs

Q: Can I use a Glock 43X slide on my Glock 48?

No. The Glock 48 and 43X use the same frame, but the slide lengths differ. A 43X slide will not fit properly on a Glock 48 frame.

Q: Does the Glock 48 MOS slide come pre-cut for optics?

Yes. The MOS version of the Glock 48 includes a factory optic cut for micro red dot sights like the Shield RMSc or Holosun 507K.

Q: Is the Glock 48 slide compatible with aftermarket barrels?

Yes. Most aftermarket barrels designed for the Glock 48 will fit this OEM slide, but always verify compatibility with the manufacturer.

Q: Can I use a Glock 19 slide on a Glock 48 frame?

No. The Glock 19 uses a wider, double-stack frame that does not match the Glock 48’s slimline design.

Q: Will customizing my Glock 48 slide void the warranty?

Yes. Modifying the slide with milling or aftermarket optic cuts will void Glock’s factory warranty. Proceed with caution or consult a certified armorer.
