W-kin <7,5 Joule
markings: F in pentagon, caliber and dealer
try to ask one of the bigger german dealer witch is allowed to stamp those markings for a "einzelgutachten", that means that your gun would be tested to complie the regulations and ,if it pass, get the markings.
but it may be easier and cheaper to buy an gun in germany or use a rental.
if it would be easy i would have already tried to get my fingers on a DSP...
