Assault weapons are banned in Spain, right? Also, you can't just openly carry guns of any kind on the street over there? Am curious about this.
Might as well be an excuse for a bit of an expository rant:
You can get licenses for everything from sword canes to firearms just under mounted and automatics (which only specific security firms and border patrol and customs get a license for), but I think it's descriptive enough that the law doesn't contemplate any use of weapons that isn't for sports or hunting, as the (latest) constitution reads, "The Spanish State has exclusive competence over production, acquisition, selling, possession and usage of weapons explosive or otherwise" (roughish translation), of course, with exceptions by judgement of entitled entities when it comes to harm to the parties involved and severe future risk.
Of course it changes all the time because people don't jerk themselves off to Constitution, but the general lines stay the same. You need a personality/physical condition test, criminal record and a stated case to why you'll need it for one of the tiers of license and then go buy to the actually pretty hard to come by gun stores.
There are monthly inventory checks for the status of each weapon and its owner’s location, which is doable because there are like way less than a hundred thousand normal license owners, most being business owners like jewelers, judges, ex-military, sports players, and politicians. Most gun owners are in fact hunters, on around the million or so. If anything, the lowest tier is a bit too hard to get and for situations like domestic abuse it's hard and rare to actually be granted it, and thus some loopholes have been exploited by people who felt distressed, like keeping target training guns. Also no, no open carry whatsoever. You won't be shot if you're a dumbass and wave around airsoft replicas, but you'll certainly get some REALLY pissed off cops.
Funnily enough, a common motto of ANA (our NRA equivalent) is that security isn't a pretext to override any rules, even if the right to self defense should be upheld, of course. They're a lot more rigorous, if also less prominent in politics. Of course they are trying to budge for some leniency and raise awareness for the black market, which is fair enough. It's a notable problem as despite the almost draconian regulations we're the world's 7th top gun exporter.
Personally, I don't even know any gun owners that aren't hunters and since my grandfather died not, and not even that as he barely even used them. Only time I got to shoot a live weapon was shortly before he passed and I blatantly missed the ducks I was pointed towards. Where I live about 1 in a 500 people own one, and as I implied earlier gun stores are hard to come by and the couple I know are really sporting and hunting goods shops. Nationally there's about 80-100 gun related homicides total a year, and when it comes to terrorism half the deaths in contemporary history coming from a single attack on 2004, which was sparsely followed by radical extreme nationalist Basque organization ETA, which finally disbanded and stopped fire on 2016, to be followed by the latest yihadist attack since the 2004 one as of 2017, and mass shootings are very rare and situations that could make them end up with 1-3 dead tops, in their rarity.
Overall, it's even stiffer than the usual European standard preconception. But really, besides relaxing some other terms, it's generally fine in its current state. And no TLDR no open carry, no
