Happened to see this handy overview of what's legal here. Most of this I already knew, but I wasn't aware of the number of guns available to the general population given Portugal's low firearm-related murder rate.
We were engaged in a tremendous amount of planning leading up to our relocation to Portugal. Being an engineer by trade, I had actually prepared a GANTT chart with all the projects that were needed prior to our leaving the U.S., a process that involved a lot of reading and research to make sure that everything was checked and double-checked. We made sure to have legal assistance every step of the way.
Of course, there was an unexpected glitch: my name.
