I love my cans too. It is just a pain in the rear here to obtain one.
We might have some of the strictest laws on firearms in the world, where only a convicted terrorist (IRA) seems to be able to get a certificate for a handgun for self defence. Certainly none of the former targets of said terrorist, the current and former members of HM Armed Forces are to be trusted with one.
But that aside, at least as far as sound suppressors are concerned, the suppressor is classed and licensed at the same level as the firearm to which it is to be fitted. Which can lead to some anomalies. The big cans for centerfires are OK, since you are not likely to want to use them on something smaller. Since a lot of folks use the same type of 1/2" UNF fitting moderator for both .22LR, which is licensed, requiring that the moderator be entered on a FAC, and on an air rifle under 16J (12fpe) energy which is exempt from licensing and so then is the sound moderator. If you have one for each, one will be on an FAC and the sale or transfer is restricted to other FAC holders with the correct authority to acquire, or a licensed dealer. The other is completely unregulated. Fortunately most sound moderators in the UK have no visible maker's name or serial number, so you don't have to worry about screwing the unlicensed airgun one to your licensed .22LR and using an "unregistered" moderator, which could lose you your FAC if the police decided to be difficult. You could technically, I think, get a 5 yr sentence for fitting the registered moderator on your unlicensed airgun. As technically it is a Section 1 firearm and controlled as such, but you will have a certificate for it. But again the most likely result is losing your FAC and your ALL your guns without compensation. It just depends on how anti gun any particular police officer is, and the same with the lawyers at the CPS.
Saying all of that as far as I know there have been very few if any incidents of this nature that have resulted in loss of a certificate, or criminal charges. So although it can happen it's pretty unlikely as long as you are not an idiot.
