Here is some more information about the HK VP9SK.

The eagerly anticipated subcompact model of the acclaimed Heckler & Koch VP Series handgun, VP9SK (in 9 mm) has all of the sought-after characteristics of larger frame VP pistols but in a more concealable design.

The highly-rated HK VP precision strike trigger is also found on the VPSK. The VP trigger surpasses those found on competitors. It has a short, light take-up with a solid, single action type break followed by a short positive reset. The net result is trigger quality unmatched in production striker fired pistols.

A small-scale interpretation of the completely adjustable VP grip feature — consisting of interchangeable backstraps and lateral grip panels — is replicated in the compact grip frame of the VP9SK. This allows the pistol to be easily modified to fit any individual user and is a feature found only on Heckler & Koch handguns. Molded finger grooves in the front of the pistol’s grip also instinctively position an operator’s hand for optimal shooting.

The VPSK has the features of the latest, state-of-the-art handgun. All controls are completely ambidextrous. Slide releases are present on both sides of the frame and the paddle style magazine release can be easily activated by left- or right-handed shooters.

HK’s patented charging supports, found on full size VP pistols, are also present on the VPSK. The charging supports are simple components that are mounted on each side of the rear of the slide and provide better gripping leverage for racking the slide rearward. The charging supports speed reloading and make operating the VP easier for shooters with reduced hand strength.

VPSK pistols can use a variety of proven HK magazines, including compact double stack 10-round flat floor, 13/15-round extended magazines for a more ergonomic grip.
