Compatibility

This slide fits Glock 25 Gen 3 frames and Gen 3-compatible components. It is not directly compatible with Gen 4 or Gen 5 frames without modification. Use a standard .380 Auto Glock 25 barrel for proper fit and function; note that the Glock 25 slide and frame are dimensionally similar to the Glock 19 but chambered differently, so components are not generally interchangeable across calibers.

Constructed from hardened steel and finished with Glock’s durable coating, this slide is built to withstand extended use in duty or range environments where legally available.

Customization Options

• Sights: Upgrade to night sights or fiber-optic options

FAQs

Q: Is this slide optic-ready? A: No — this is a standard Gen 3 slide without MOS capability.

Q: Will this slide fit a Glock 19 frame? A: No — while dimensionally similar, the Glock 25 is chambered for .380 Auto and its components are not a direct caliber-interchange with Glock 19 (9mm) parts.

Q: Does the complete slide include a barrel? A: Yes — the complete version includes a factory Glock 25 barrel in .380 Auto.
