Belgium:
"Until 2006, Belgium had surprisingly lax gun control laws. After a man shot two innocent people, however, the nation become increasingly concerned with the illegal flow of firearms. The 2006 legislation requires gun permits to be renewed more frequently and sought to prevent the impulsive purchase of guns by requiring prospective gun owners to go through a three-month process which includes an extensive police screening. Six years later, in 2012, the European Union passed regulation aimed at interrupting the transportation of guns across borders by requiring exporters to obtain a special license.
Today in Belgium, it's not easy to own any type of gun, unless it's a rifle or shotgun. The nation prohibits the private possession of fully automatic weapons, and permits ownership of semi-automatic weapons only in certain case scenarios. Furthermore, the private possession of handguns is only allowed after obtaining special permission from the government. In the country, long guns, such as rifles and shot guns, are the only guns not prohibited by the state. According to GunPolicy.org, these regulations categorize Belgium as a country that has "restrictive" gun control laws."

Czech Republic:
"The most recent statistics show that on a per-capita basis Czechs own about one-tenth the number of guns Americans.... Still, owning a gun in the Czech Republic isn't so easy. Permits are for 10 years and are reviewed after five years. People have to pass a written and practical test, as well as a medical check that includes mental health, and a clean criminal record...
Mass shootings are rare in the Czech Republic, but not unknown. In 2019, seven people plus the gunman were killed in Ostrava, and in 2015, eight people plus the gunman were killed in Uherský Brod. There was also a case in 2009 with four victims plus the gunman."
