Compatibility

This slide fits Glock 43X frames and slim-frame compatible components. It is not compatible with standard-width Glock frames (such as the Glock 19 or Glock 26) without modification, as the 43X uses a narrower single-stack slide and frame profile. Use a standard Glock 43X barrel for proper fit and function.

Materials & Finish

Constructed from hardened steel and finished with Glock’s durable coating, this slide is built to withstand extended daily carry use while maintaining a slim, print-resistant profile.

FAQs

Q: Is this slide optic-ready? A: No — this is a standard slide without MOS capability. For optic mounting, see the Glock 43X MOS OEM Slide.

Q: Will this slide fit my Glock 19 or Glock 26? A: No — the 43X uses a narrower single-stack slide and frame profile that is not interchangeable with standard-width Glock models.

Q: What makes the 43X different from the standard Glock 43? A: The 43X uses the same slim single-stack slide width as the Glock 43 but pairs it with a longer, higher-capacity grip frame for a more full-size feel in a concealable package.

Q: Does the complete slide include a barrel? A: Yes — the complete version includes a factory Glock 43X barrel.
