  • All HK USP Full Size Pistols
  • All HK USP Compact Pistols
  • All HK P2000 Pistols (All Models)

  • HK45C this is the factory upgraded mag release for this model
  • Will not fit the HK45 full size, P30, P30L, VP9 or Mark 23 Pistols.

Installation Instructions:

This is a simple straight forward parts swap and can be done in a few minutes. The end result is a much easier mag release and better comfort for mag changes. Highly desirable and one of the cheapest upgrades you can do to your HK pistol.

Simple install: Use a 2.8mm punch to drive out out the roll pin. HK suggests replacing the roll pin (clamping sleeve) EVERY time you remove any roll pin. Pull down on the mag release gently, remove the spring (replace spring if needed) from the old mag release. Replace the mag release with the new HK 45C mag release. Re-install by compressing the spring in place, and pushing the new roll pin in place. We have both the 3mm roll pin and the magazine release spring in stock below so grab a few spares. Swap out all of your HK mag releases with this upgraded version. It is the best upgrade for the money on your HK pistol.
Please note: In some cases, the extended magazine release will not engage the jet funnel magazines properly. It is best to use them with standard magazines only on the USP full size pistols.

Please Take Note: That although this mag release will fit all of the HK models listed above this is not an approved modification by HK. This magazine release is designed specifically for the HK45C as the standard OEM magazine release and not a factory upgrade for the HK pistols mentioned above. This new style magazine release has a steel insert. That makes contact with the magazine catch notch. And if installed on a USP pistol using polymer magazines. The steel contact point can eventually dig into the polymer magazine and cause the magazine fitment to become loose and possibly for mags to fall out. HK does not approve this modification especially for L.E. use.

"Great upgrade for my USP Compact 40"

Very easy install, took about 3 minutes.


"Great OEM Upgrade"

Overall Product Rating:


This simple modification will make your HK much easier to function and can always be removed. I have installed the HK45c magazine releases on both a full size and compact USP and a P2000. The fit has been perfect on all of these guns. The process is very easy using the credit card method mentioned already. I recommend buying a roll pin punch to do the procedure, 3mm Mayhew "pilot punch" is the best fit although the SAE sizes can be used. If you want to take the extra step to ensure a smooth inst... More details

Simple install. If you can drift a roll pin out and back in, you can do this!

"Great Addition"

A perfect addition to my P2000 SK. The stock mag release was difficult to use. So glad I switched them.


"Extended mag release"

James Longmire on 3/11/2012 11:03:39 AMVerified

Overall Product Rating:


I found the stock mag release was very small and difficult to eject the mag. The extended release is great and a release using the shooting hand is now possible.

Quick shipping, OEM H&K parts. Extended mag release is an easy install. Order it now!


"Excellent mod"

Pete on 9/19/2011 1:47:02 PMVerified

I bought the extended mag release for my P2000 and P2000sk. The parts arrived within days of being ordered. They were very easy to swap out. I removed the roll pin, removed the old mag release, and put the new one in without any trouble. The only thing I would caution people about is when used with a SERPA holster the new mag release catches on the holster. I removed some of the holster and resolved that issue.


"Excellent Part"

This truly is one of the best and cheapest upgrades for your HK. I am not an armorer but it took me 5 minutes to put in and makes mag releases so much easier!


"extended mag release"

I knew it would be an improvement but wow what a difference. This is one of the best things you could add to your usp and definitely the first upgrade. Very happy with the after release now and the install was super easy and took about 3 min. The service and shipping was probably the fastest I've ever had from any other company. Will be ordering more stuff for my USP from these guys in the future.
