A friend of mine posted something about it that he picked off a message board. And then someone else posted a link to a news story. Sounds like it's real but not a big deal. The two stories match up fairly well. Here's the message board story:
"What a day! At the airport in Amsterdam we were all lined up at the ticket counter checking in for the flight to Oslo. The 35 pieces of luggage to check were being lined up and I turned to ADAM, our Tour manager and whispered Remember there's a gun in our bags referring to the replica Glock 45 handgun that we use on stage. In a second of confusion he says to the ticket agent, Oh yeah, not to worry but we have a gun in this suitcase. Before he could explain that it wasn¹t a real gun but a replica, airport Police swarmed in on us and the questioning began. Apparently, unknown to us, any gun, whether real or fake, is highly illegal in Holland. Quick thinking ADAM realized that this was suddenly getting ugly and that we might get detained and miss the flight, thus putting the show in Oslo in jeopardy. He instantly informed them that the bag in question was his. Before I could blink, they arrested him and took him away. He looked back at me and said, Don't worry get on the plane and I'll call you later. As I watched him being led away the ticket agent handed me my boarding pass and said, Have a nice flight. Right. The rest of the entourage boarded the plane and journeyed to Oslo without further incident. Just before show time a very stressed out ADAM burst into our dressing room full of tales from his eventful day. There was no jail time only a fine and oh yeah ? they confiscated the gun. I was in Oslo in January for a press tour and it was snowing and minus 10 below, but today it was sunny and 80 degrees. I love Oslo, it's a very beautiful city and the people are friendly and really love music. The show keeps getting better and the fans that were there, although small in number, were loud and very supportive."
And
here's the news story:
(6/13/06 - LOS ANGELES, CA) - Queensryche have learned that even a toy gun brought on an airplane can be considered smuggling.
The band's label representative says Queensryche was checking in at Amsterdam's airport for a flight to Oslo, Norway. He says one of the bags contained a prop toy gun that singer Geoff Tate uses in their stage show.
He says all guns, even toys, are considered illegal in Norway. He says Queensryche's tour manager was detained and had to pay a fine, but has since been released.
