Congratulation Iowans.
Pennsylvania doen't have Constitutional Carry. I wish we did. But for now we are a "shall issue" state which means the local County Sheriff can not deny you a permit without a specific reason. Mostly that means if you are not insane, a felon or a habitual drunk, you will be issued a carry permit.
Well, one thing I know, Maryland doesn't honor ANY OOS CDW permits.
Or New Jersey and New York
Pennsylvania's License To Carry (LTC) is honored by 32 other states. Unfortunately, it is not honored by many of our neighbors. The communist states of Maryland, Delaware, New Jersey and New York are reluctant to issue carry permits to their own citizens. They sure aren't about to honor permits from another state.
