1. All pistols (except revolvers) are semi-automatic.
2. High capacity is not a descriptor of a gun, but of the magazine holding the bullets.
3. The stats are all right in the link I posted. Handguns account for the vast majority of gun deaths, but gun control debates are dominated by talking about regulating rifles.
4. Sub-400 people per year in a country with 14,000 killings that year is a negligible number, regardless of any eye rolling.
