Welcome to the Dark Side. you state that you got your CC? does this mean you got a Conceal Carry Permit? if so, then you have in fact received a LTCF (License to Carry a Firearm). PA only issues LTCFs.
i Highly reccomend a defensive pistol class before you start carrying so you know how to handle most situations you might come into.
The F.I.R.E. Institute is a great place to get proper training and they are located in Pittsburgh.
any other questions, just postem up and we'll do our best to answer them.
be safe, Chris
