Congratulations on taking the step to exercise your 2nd Amendment right.
Since Wilmington is in close proximity to Pennsylvania, I have found it
beneficial to obtain my PA (Out of State) Permit as well. While you are
having your digital finger prints taken for Delaware, for a small fee you can
have an FBI Print Card rolled in case you want an Out of State Florida
Permit, as well. I believe Radnor can assist you with this. With these three
Permits, you currently get reciprocity in 31 states. It's also a good idea to
find out why, under any circumstances you would NOT want to concealed carry
in either New Jersey and Maryland, and what steps you must take to bring
a fire arm across those state lines.
