Every HK owner should upgrade. Read the many raving reviews and you will see what you have been missing. Now finally available & hard to find!

  • All HK USP Tactical, Elite & Expert Pistols
  • All HK USP Full Size Pistols
  • All HK USP Compact Pistols
  • All HK P2000 Pistols (All Models)
  • All HK P2000SK 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.

"This should come standard on all USP"

Ryan on 1/4/2013 9:44:47 PMVerified

Overall Product Rating:


The feel of the normal and the extended are pretty much night and day. While there really isn't much wrong with the standard one, the extended just gives you more real estate to deal with. Still works with my Safariland holster


"HK Extended Mag release."

RUSSELL SCHUCKERT on 6/22/2011 6:22:28 PMVerified

Overall Product Rating:


This is a great upgrade for the P2000 series. Install was quick and easy and now it is much easier to release mags. Thanks for the quick service.


"Wish I had this 9 years ago"

Lee Hunkovic on 4/10/2012 12:37:26 PMVerified

Overall Product Rating:


This magazine release is a must have, in my opinion, for anyone who owns a USP and doesn't have very long thumbs. It definitely improved my reloads, allowing me to shift my grip much less when dropping the magazine. If I ever get another HK, this will be a standard upgrade. Money very well spent.


"USP & USP Compact Magazine Release"

D J on 7/12/2013 3:37:20 PM

Overall Product Rating:


A great improvement. Works flawlessly on USP .45, USP Compact .40, and USP Compact .45. Note however, that on the USP .40 (full size) the original mag release has a plastic tab instead of a metal one (to engage the plastic magazine.) If you install this extended release with the metal tab, it will start to gouge and score the plastic magazine body. It works fine, but will eventually take it's toll on the .40 plastic magazines. I love the ext. mag. rel. on the others, but will leave it off of the... More details


"fast, accurate service"

I ordered magazine release extension for a USP. Part arrived in record time. Easily installed, works great.


"Small upgrade with Big returns."

Carlos Rojas on 1/4/2014 12:09:04 PMVerified

Overall Product Rating:


This fairly inexpensive upgrade might seem like a small modification. It will, however, change the overall perception of your HK and increase your pride of ownership. People who don't run HKs love to bash the "European style" mag release. The position of the release is far more ergonomic and accessible than most modern pistols and those with 100 year old designs. If you've manipulated a P30, HK45, or an HK45c you'll probably better understand my argument. The small increase in surface area great... More details


"Best and easiest upgrade"

Took me 5 minutes to install this. Made a huge difference in the ability to drop the magazines. Definitely worth the upgrade.


"Excellent Part"

chad jones on 4/8/2012 9:33:10 PMVerified

Overall Product Rating:


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!


"Great upgrade"

jeray on 5/7/2013 9:48:51 AM

Installed on USP Competition Combat in 9mm. Works great, easy to swap and makes mag changes much easier.


"Best no-brainer upgrade for your USP"

Michael Coogan on 9/3/2012 4:59:19 PMVerified

Overall Product Rating:


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