Well, the one i have, is the 1000s, and the first time the trigger didnt engage, then, i sent it back to Hatsan and they sent me another rifle, this rifle had the barrel loose, so i sent it back, then they sent a third rifle, three weeks later it lost power, so i sent it back, they fix it and now it lost power again and im waiting for it again, so i dont know if this is the only case or there are someone else's having problems too
