Take your pick. The pandemic, the police killing of George Floyd, the presidential election. Protests, looting, calls to “defund the police.” Any one of such similar events historically has been enough to push some people off the fence, prompting them to finally buy a gun or add to their collection. But with a wave of crises crashing across the country, more than 40,000 Illinoisans applied for a gun permit in a little more than two weeks this month, more than 500% over this time last year, according to Illinois State Police. Gun sales are soaring at Mark Glavin’s gun shop in Elgin, from an average of 10 a day last year to as many as 200 a day this year. With so many gun purchases, he said, ammunition also can be hard to find. “Take a full glass of coronavirus, shake in a shot of riots and another of this defund police notion, and everything goes crazy,” said Glavin, owner of Fox Valley Shooting Range. “Not to mention the backlog on background checks.”
