HK USP Magazine Extension - 9mm - +7 Round

HK Parts Magazine Extension for your HK USP or HK USPT 9mm +7 Magazine Extension

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

Made in the US from aircraft-grade hard coat anodized aluminum with steel hardware. Ultra-low profile & rock solid. With the addition of the +7 mag extension, the round count increases from a 15-round magazine to a full 22 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 does not fit the HK USP Compact 9mm or the USP .40 and will not fit or work with the 10-round USP 9mm magazines.

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).
