While this is not the perfect / inexpensive solution to the lack of grip options for the CZ Scorpion, it does work well and it gives you more options.
I was not not impressed by the current pistol grip offerings for the CZ Scorpion. While browsing thru various grip options on Google Images, I stumbled upon the Thordsen Customs EVO Adapter. Since Thordsen stocks are designed to fit a standard AR15 lower and this adapter is made to fit a Thordsen stock to a Scorpion EVO, I thought that I'd take a chance and see how it would work with a AR15 pistol grip.
Most of the AR15 pistol grips are not going to change the angle of the grip. But the Magpul K2+ does provide a steeper angle that I find comfortable. It's not a perfect fit. I had to file a little off the grip so that the edge just above the finger well does not rub against my index finger.
