It can be done, but is highly unlikely for you to get one. And, if you do get one it will be highly restricted depending on your justification.
My advice; don't bother with it. Can't carry daily if you work on post so the weekdays are a wash for you anyways.
Live in PA (not that far of a drive), get your permit there. Then, stay out of MD all that you can.
