Frequently Asked Questions

Will this magazine fit my HK SP5 or other MP5-pattern pistol?

This KCI USA magazine is designed to fit MP5, SP89, MP5SD, and HK94 platforms chambered in 9x19mm. While it is compatible with many MP5-pattern firearms, fit can vary slightly across different manufacturers' clones and semi-auto variants. We recommend verifying compatibility with your specific firearm before purchasing. It is not intended for use with .40 S&W or .45 ACP MP5 variants.

Is this magazine truly blocked to 10 rounds, or can it be modified?

This magazine ships as a permanently blocked 10-round California-compliant magazine. The locking plate is spot-welded in four locations, making it structurally secured within the full-size 30-round body. It is sold and intended for use as a 10-round magazine in compliance with California's magazine capacity restrictions.

How does the Cation Electrodeposition coating hold up to regular range use?

Cation Electrodeposition (CED) coating is an industrial-grade finish that provides excellent corrosion and wear resistance, making it well-suited for frequent range use and storage in varying conditions. Combined with the hardened steel body, this magazine is built to withstand the rigors of regular training sessions. Periodic wiping down with a light lubricant will help maintain its appearance and longevity over time.
