but get caught in a place with one and you'll lose your permit (and therefore your handguns).
I've never heard this one. The signs have no force of law. They can ask you to leave and if you do not, then you are trespassing. But since you are concealed, you aren't going to get caught. Bars not a problem. Schools are no gun zones legally as are gov't buildings.
I've never talked to anyone who moved from out of state, so I don't know how that complicated the process. You do have to have three references and this may be an issue because they have to have known you for a certain period of time and I think they have to reside from the same county. These two restrictions may be a county thing, so Erie may do it different. Since judges change over the years, so does the process. Once you have a permit, carry is less restrictive than many other states.
Since you state that you have to move, just don't bring your guns into the state for now and you will have time to get the straight scoop from the county clerk where you move. The SAFE Act does require them to have access to your medical records. That sucks.
Magazines are limited to 10 rounds. If you have magazines that hold more than that, you can put a block in them to limit them, but you need to rivet the base or hot glue it to make it "not readily modified" to hold more than 10. Mine are blocked.
You can have an AR-15, but it has to meet certain restrictions. Stock is not adjustable, no thumbhole, no pistol grip.
