I work in md, live elsewhere, and recently got my hands on the "new" applications. Apart from the standard fare (completing the training course, paying fees) the application is 13 pages, requires (among other things) two notarized sections, digital fingerprints, and three references.
That being said, It's still up in the air. Last I heard (and it's probably changed) apps could be filed August 8, 2012.
The trick MD has adopted recently to disarm its citizens is to send letters to CCW carriers. A family friend of mine, a retired NYC cop, was recently told via letter that "since [he] hadn't been involved in any incidents or needed to defend himself since requesting [his] permit, the state was deeming it unnecessary."
And as such they refused to renew his permit.
I say the only hope for MD is if they pass the national Reciprocity bit that's been gaining steam, at least then neighboring states can carry while in MD...
