FAQs

Q: Can I use a Gen 5 slide on a Gen 3 or Gen 4 frame?
A: No. Gen 5 slides have internal changes and won’t fit older frames without major modifications.

Q: Will OEM parts work in aftermarket slides?
A: Most aftermarket slides accept OEM parts, but always check for compatibility before installation.

Q: How often should I replace the recoil spring assembly?
A: Glock recommends replacing it every 3,000 to 5,000 rounds.

Q: Will modifying my slide void the warranty?
A: Yes. Custom cuts or other changes can void the Glock warranty. Talk to a certified armorer before making changes.

Q: Can I mount a red dot on my Gen 5 slide?
A: Yes, if it’s an MOS model. You can also use a custom-cut slide for optic mounting.
