I'll be making a trip south in upcoming days and I'll have to pass through the state of Maryland. I was stationed there about 8 years ago, but I'm sure things could have easily changed since then.

I know my CCW is not valid there; while within the state am I good to go if I just unload, remove the loaded mag from the gun, and keep the empty pistol and loaded magazine and ammo in separate compartments? I'll be in a truck, no trunk. Also possession of hollow points is good to go right? I wouldn't get a specified amount of jail time per HP bullet like you do in NJ?

Thanks

No problem at all with hollow points.

Rest of your plan sounds OK.

 You should not have to unload your mags.  There's an AG letter on it.

However, it would not hurt.  And I do not assume every MD Leo has read the AGs letter.  Ymmv.

Nope, just passing through on the way to Virginia.

There was one single case (that we know of) where a Florida CCW holder got tailed, then pulled over after passing through the I95 tunnel with his family (think it was even a minivan he was driving).  

The only reason appeared to be the computer database of Florida CCW holders the police obviously have.  Op , they probably know about your PA permit as well as my VA permit; don't be surprised if they ask about it if you get pulled over.  They know everything these days.

But as far as I know, they immediately dropped any practice of stopping drivers for that alone.  I haven't been hassled, and I visit MD a lot (though not through the tunnel).  Is that your route?
