I think there's probably a lot, and that would likely need a bit of exploration to understand. I think right now if I order a firing pin out of Germany, there's no tracking of it. There are no requirements for that to be regulated in any way, whereas if I go to buy a firearm, ammunition or something else, in most cases there's a need to produce some sort of licence that shows I can do that.
We had a recent case in Saskatchewan where a person was fairly sophisticated in their ability to produce not only a firearm predominantly made from a 3-D printer, but one that would fire 40 or 50 times while it held the integrity of the firearm. You need it to be able to fire only once for it to be fatal and used in a homicide.
I think if we can somehow work on the importation of parts, and perhaps there are some other things.... I don't know what best practices exist in other countries, but again, it would be an exploratory piece of work to look into that.
