It isn't a replica - a replica doesn't do anything but look like a gun. Replicas aren't handled like a gun, they are simply forbidden. You can't get a license to own a replica firearm. Blue guns aren't replicas either, both the SIRT and the Blue Gun are classified by the police as training devices. Customs has decided to define the SIRT as a replica, and since they can't be challenged, most of us are stuck since they're in limbo. If you own one, the status is unclear, so if you want to sell it, it's a gray area. In short, you can have it, but you can't get it, and if you've got it, you can't sell it, but you aren't breaking the law. For what they are, they work very well, but given our dollar, and the fact that the Pro is now over $400 US, I can't see why you'd want to pay that.
