One year after a change in Iowa law required county sheriffs to issue concealed weapons permits, without restriction, to anyone who applies and meets certain requirements, the number of permits issued in Allamakee County has more than doubled. Allamakee County Sheriff Tim Heiderscheit said that prior to the passage of the new law, 256 concealed weapons permits had been issued in Allamakee County, while after the passage of the law, 312 new permits were also issued.
