I am curious as to how the law defines (as per a shotgun cert) preventing "access to shotguns by an unauthorised person". Specifically, would use of a trigger lock (e.g. Master Lock Trigger Lock | Canadian Tire) meet this requirement? In Canada you are not required to keep firearms in a safe, but instead can just use a trigger lock. Is it reasonable to think that this would be true in the UK? Any insights would be greatly appreciated.
