Well, after a little digging around I found the bill:
MD HB 52
Short, sweet and to the point at just over 3 pages long. The bill only refers to recognition of PA, DE, and VA permits, but does not change anything about the ability to obtain a MD permit (i.e. may issue to shall issue.)
One other thing it
seems to do is include a list of 45 various "assault weapons" as legitimate carry weapons. I find it hard to believe that that is what it actually does, but I can think of no other reason to include such language. Guess that is why I'm not a lawyer.
BTW, I have found discussion on other forums (I stray from time to time :biggrin

stating that the omission of WV from the bill was an oversight, and that the bill's sponsor plans to add WV in an amendment.
