The HK VP9SK is a compact version of the HK VP9 that was introduced in 2014. It is a striker fired subcompact that makes a really nice concealed carry pistol. The barrels in the VP9 series pistols have been tested up to 90,000 rounds which is in keeping with VP quality.
The VP9SK has some great features such as the mag release is part of the trigger guard and the grip is adjustable by changing out the back straps. The serrations on the slide are perfect making racking the slide very easy.
Here is a really good review on a very fine pistol.
Excellent review.
