❓ FAQs

Q: Can I run a Gen 5 slide on a Gen 3 or Gen 4 frame?

Q: When should I replace the recoil spring assembly?
A: Glock recommends service every 3,000–5,000 rounds.

Q: Do custom slide cuts void the warranty?
A: Yes. Any modification may void Glock’s warranty. Consult a certified armorer first.

Q: Can I mount a red dot on a Gen 5 slide?
A: Yes — MOS versions support direct red-dot installation using adapter plates.
