HK VP9SK, P30SK +5 Magazine Extension Kit

Magazine Extension Kit +5 - HK VP9SK, HK P30SK

HK Parts magazine extension kit adds 5 additional rounds to the HK VP9SK/P30SK magazine with the simple swap of the floor plate & high-reliability mag spring. 

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

Compatible With:

• HK P30SK
• HK VP9SK

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).
