I'm thinking of buying some parts for a Cz pistol from the us, it's just springs and possibly a hammer upgrade. My question is can I legally buy these bits and have them shipped to me or am I breaking some sort of law by doing so? The manufacturer has said they will refund me if customs return them to sender but I don't want to get into trouble?? I cannot buy the bits in the uk as no one has pistol parts anymore. And have been quoted €40 postage to get them from a company in Estonia. What to do???
