I posted this on another thread a while back, (last year) but since the question is recent, I'll give you some info.
The courthouse is located on N. Duke St. Sherrifs office is just down the hall from the entrance. There are several parking lots in the area close by.
When I went to get mine, there was another gentleman in front of me, also from DE.
I handed the completed app to the nice lady at the desk. She took my $20 (I think it may be $25 now). She handed me a receipt and told me to have a seat. Before my butt hit the chair, she was on the phone with PA State police doing the background check. about 2 minutes later, she hung up the phone, stamped my app, passed it down to the guy taking pictures and printing permits.
Had to wait till he finished with the gentleman in front of me, took my picture, punched in the info, print, laminate, done.
Total time, 19 minutes from start to finish.
I love my home state...........
