Compatibility

Glock made this slide specifically for Glock 27 Gen 3 frames and Gen 3 parts. It will not reliably fit Gen 4 or Gen 5 frames without modification. Use only Gen 3-spec barrels, RSA, and upper internals for best results.

Materials & Finish

Glock machines the slide from hardened steel and applies a factory protective finish to resist wear and corrosion. The finish reduces glare and helps the slide withstand daily use and harsh environments.

Customization Options

• Sights: Swap factory sights for night sights or fiber-optic options.
• Finish: Apply Cerakote or other professional coatings for a custom look.
• Milling: Have a qualified gunsmith mill an optic cut (note: milling an OEM slide may void warranties).
• Engraving & Serrations: Consider custom serrations or laser engraving for grip and aesthetics.

FAQs

Q: Does the complete slide include internal components?
Yes — the complete slide ships with barrel, RSA, and all upper internals. The stripped slide does not.

Q: Is this slide optic-ready?
No. The factory Glock 27 Gen 3 OEM slide comes without an optic cut.

Q: Will this slide fit a Glock 19 or other models?
No. The Glock 27 slide matches the subcompact dimensions and Gen 3 spec; it won’t fit full-size or later-generation frames.

Q: Will modifying the slide void the warranty?
Modifying or milling the slide typically voids the manufacturer’s warranty. Check Glock’s warranty policy before altering an OEM slide.
