Sorry I meant to add this statistic (updated now):
"The most recent statistics show that on a per-capita basis Czechs own about one-tenth the number of guns Americans."
The Czech Republic has 10% the per capita gun ownership of the US, and some moderate controls on ownership, and suffers from occasional mass shootings. That seems to me consistent with the idea there's a relationship between gun ownership, and its lax regulation, and mass shootings.
The Czech Republic has less ownership, a bit more regulation, so has less mas shootings. But it still has them because those values are not 0.
