The United States experiences mass shootings which cause the American public to respond in various ways. One measurable aspect is the demand for firearms following a shooting. Using the Federal Bureau of Investigation’s National Instant Criminal Background Check System to proxy firearm sales, I create an ARMA model that estimates which characteristic of a mass shooting dictates the largest firearms purchase response. I find that President Obama’s tenure caused 210,000 more firearms sales per month. I also find that if the mass shooter was an internationally influenced terrorist, firearms sales increased by about 420,000 for the two-month period.
