Description
The 50/50 Banded California Kingsnake is a high-performance, two-tone magazine extension designed for shooters who demand reliable capacity and a secure grip. It adds +5 rounds to compatible Glock 17/19 magazines while maintaining a low-profile, snag-free design. We added this to our catalog in late 2025 based on consistent positive feedback from our customers regarding its fit and function. One customer did return it for being ‘too tight,’ which we traced to an aftermarket frame—it fits OEM frames perfectly.
Stand-Out Features
- Two-Tone Banded Design: The distinctive black base with a tan band provides a unique, tactical aesthetic that stands out from solid-color options.
- Positive Grip Texture: Aggressive texturing on all sides ensures a firm, non-slip hold during rapid reloads, even with wet or gloved hands.
- OEM-Specific Fit: Engineered to precise tolerances for a seamless, rattle-free fit on factory Glock frames. Aftermarket frame compatibility is not guaranteed.
- Durable Polymer Construction: Made from a reinforced, impact-resistant polymer that withstands drops and hard use without cracking.
- Easy Installation: Uses the factory magazine spring and follower. Install in seconds with no gunsmithing or permanent modification required.

Your Questions Answered
Will this fit my aftermarket Glock clone or P80 frame?
It is engineered specifically for OEM Glock frames. We have had returns where it did not fit properly on aftermarket frames. For guaranteed fit and function, use only with factory Glock frames.
Does it come with an extended spring?
No. This extension is designed to use your magazine’s existing factory spring and follower. This simplifies installation and maintains reliability with proven components.
Is the color pattern consistent?
The ‘California Kingsnake’ banded pattern features a tan band over a black base. While the color application is consistent, slight variations in the exact line of the band can occur, which is normal for this style.
