HK USP 9mm +10 Magazine Extension

Magazine Extension - +10 - HK USP 9mm 

Easy to install. Simply add the mag extension to your existing mag body and follower. No gunsmithing needed.

Made 100% in the USA out of aircraft-grade, hard-coat anodized aluminum with steel hardware. Ultra low profile & rock solid. With the addition of the +10 mag extension, the round count in the magazine will increase from a 15 round magazine to a full 25 rounds. Ideal for competitive shooters, concealed carry, or range day mag dumps!

HKP highly recommends using a magazine loader when loading ammunition into our extended magazines due to increased spring tension versus factory.

Compatible With:

• HK USP 9mm
• NOT compatible with HK USP with Jet Funnel

Please note: This listing is for the magazine extension ONLY. This is not a complete magazine.  The referenced magazine capacity is the total capacity once the extension has been added to the factory magazine (which is not included).
