Calendar. 22 business days. I submitted my application online 10/29 and got a call today to pick up my P2P and FID. I waited until 11/25 to fingerprint and pay my fees at my local PD unfortunately as didn't have time prior so even more amazing that both were done 11/25, background check finished 11/28, and call came 11/30 for pick up.
Welcome to the shooting sports... and to NJGF! I'm glad your FID process went smoothly. As you already know, there are large discrepancies between various municipalities. Some people have been held up for MONTHS... hence some of the - understandable! - griping you'll see on here. Consider yourself very lucky indeed! It sounds like you're off to an auspicious start.
