Just to clear about this court decision and what it affects...
Maryland has had a panoply of gun restrictions on the books for years.
We have a mandatory seven-day waiting period and Maryland State Police (MSP) background check for all handgun purchases and purchasers. (Even active-duty LEOs.)
We have a Handgun Roster Board that decides which guns can be sold here.
We have a one-gun-per-month limit unless you are a designated collector.
We have a ten-round magazine capacity limit.
Private handgun sales must go through an FFL or the MSP, and the seven-day waiting period applies.
So-called "assault weapons" are banned.
On top of all this, back in 2013, the General Assembly decided to license the right to buy a handgun. Anyone wishing to purchase a handgun must obtain a Handgun Qualification License (HQL), which requires that applicants undergo professional training, be fingerprinted, and pay a fee to the state for their licenses. Once you jump through those hoops, the HQL is good for ten years. It is that part of Maryland's gun law that was invalidated; everything else remains in effect.
My dancing shoes are still packed away.
