All very confusing but you can bet that SMK checked out the legal side before any expenditure was made
Whats the betting that the smk was made for markets other than the uk and they thought "sod it we'll give it a go in the uk"

Edit, I think I know how they get away with it, the valve is set at one level, the pistol barrel is machined to a length that produces 5.5 ft lbs but it wastes gas hence the silencer the rifle barrel will be able to use that extra gas to get the higher ft lbs
