As a Maryland resident, I think the bill is utterly reprehensible. Fortunately, the history for the last several years is that almost none of these quack bills get out of committee and then none of them pass the Assembly. Alas, none of the pro-2A bills manage, either; the best one can say right now is that Maryland gun laws are in a sort of stalemate.
I figure this to change, one way or another, after McDonald v. Chicago is decided by SCOTUS.
Honestly, the main problem with Maryland right now is the may-issue nonsense and the corresponding lack of reciprocity/non-resident permits. Without a permit, Marylanders are very limited in where they can have guns and how they can move them from point A to point B. With a permit, most of those restrictions go away.
Maryland doesn't have any particularly onerous high-cap law (you can't transfer 20+ in the state, but you can own them if you get them elsewhere), you can own NFA items, and you can own "assault" weapons. The training requirement is a 20 minute web-site flash presentation joke. There is a fairly minimal list of places permit holders can't carry.
After may-issue, it'd be nice to get rid of the registration requirement on handguns and "assault" weapons, but I don't see that happening any time soon.
