I submitted my application on the morning of Monday, 8/27. I had my fingerprints done via LiveScan at the Marquette City PD immediately afterward.

In the interest of being very specific, it took 14 days, 23 hours from the application time printed on my receipt until USPS delivered the permit. I know this because I also had a package delivered at the same time and an email notification when it was dropped off

Keep in mind that there was a government holiday (Labor Day) during this period.
