American Tactical Imports are importing the GSG-5P, a pistol version of the .22 MP5 patterned GSG-5.
The specs are the same as the carbine/rifle version apart from weighing 400 grams less. As far as I can see it is a GSG-5 with a butt plate instead of a stock.
The first thing I thought when looking at it was “wouldn’t that be cool in an MP5K configuration”, but bear in mind that adding a forward grip will make it an AOW.
