As I see it; in America you do have Proof testing which is that done by the manufacturers. No doubt to both protect the good name of the manufacturer and for some measure of safety for the consumer. You seem quite happy with that. But you have no way of checking a gun's safety after it has been messed around with by some back yard 'gunsmith' but for some odd reason you feel uncomfortable about some system where you can go and check (voluntarily, not compulsory) to see if it is safe or not. A bit like flying in an aeroplane that has no air worthiness certificate but you feel o.k. because it has still got two wings and someone has been round and kicked the tyres. Even with the certificate the plane might crash due to pilot error but I'd still like to know it is in a safe condition to fly in in the first place. Lagopus.....
