Description
HKP HK Parts +4 Round .45 ACP Magazine Extension for the Compact HK45 and HK USP
HK Parts magazine extension +4 adds 4 additional rounds to the HK45C, 8 round magazine. Each unit can then be fully assembled into a 12 round HK45C magazine. Ideal for competitive shooters, concealed carry, or for everyday use while at the range.
Super easy to install simply add the mag extension to your existing mag body and follower. An easy 2-minute swap. No gunsmithing needed.
HKP highly recommends using a magazine loader when loading ammunition into our extended magazines due to increased spring tension versus factory.

- HK45 Compact (8 round magazine)
- USP Compact .45 (8 round magazine)
- Does NOT fit the full size HK45
- Will NOT fit or work with the 10 round HK45C

The after the sale service was impeccable. The mag extension is awesome. It fits well and works perfectly. It is very well made and will last a long long time. I have the 10 round magazines from H&K, But I prefer this extension. It is very easy to install the extension on an H&K 8 round mag. I have an UPSC 45 and it was the only thing it lacked. I am very satisfied with it and will eventually get a second one. I would highly recommend it.

The added bonus of having extra rounds is always good for my compact usp .45. I use my .45 as a home defense gun and those extra rounds will help. It functions as intended. The aesthetics looks good too. Can't complain on this extension and definitely can't argue the price and quality this mag extension has.
