Roughly N-NE Philly...
... if you're approx. 15 minutes out from Univ. of Penn, depending on what street or blvd., still inside the Philly limits but Montgomery cnty. is just down the street, then you're most likely north of Roosevelt Blvd. , east of Fairmont Park and maybe west of the N.E. Airport.
Hmmm, pretty big chunk of real estate. Too bad you're not in Montgomery Cnty, because as soon as you had established residency, the PA CCW wouldn't have been a problem. The city has to live by the same rules as the rest of the state, though they can take their time in doing so(and do), as well as "assessing" processing fees. Pittsburgh used to think themselves above the rest of the state also, just like Philly. Ah well, keeps us in practice for watching the political rascals.
Anyway, ranges aren't all that far off. Here are some links:

These are a good starting point. Targetmaster is over in Chadds Ford along Route 202, a bit of a ride from your location but a nice adventure for a Saturday or Sunday. Target World Inc., is up in Chalfont at Route 202 and County Line Road and again, is a bit of a ride from your location. Classic Pistol is in Southampton off exit 27 of the PA Turnpike and a little closer. Pistol People is over in Bensalem, a little outside of NE Philly, but no Sunday hours(bummer!). Double Action is over in Yeadon in the Yeadon Industrial Park. That leaves Lower Providence Rod & Gun Club out in Audubon, a nice ride out 422. LPRGC is a private club with outdoor ranges but has monthly IDPA matches year round. There are others, which I'm sure fellow PA'ers here on THR will clue you in on.
BTW, if you ever get in a morose mood and wishing for the bad old days of the PRK, just move yourself across the Delaware to PDRNJ(Peoples Democratic Republic of New Jersey), where they're trying very hard to out-do either California or Massachusetts.
As an after-thought, does anyone know if Ready Aim fire is still alive over in Bristol?
