I owned a JKHAN noblesse in .22 which was basically the same gun with a fancy stock and a lothar walther barrel. They shoot VERY hot from the factory. You will need a chronograph as has been mentioned to help you get the best out of it. When I tested mine, it was shooting at 1037fps and each shot gradually got lower and lower. It was not your traditional bell curve. I put a Huma regulator and a replacement lower tension hammer spring in it. That tamed it down immensely, and gave me a high shot count (60+) at very consistent velocity of approximately 860fps and single digit extreme spread!
