The devil’s in the details @JamesCanby, that’s what I said. Capacity is not an issue in Maryland when it comes to possession, only transfer within the state borders. @TexasEskimo asked if the mags could be sent to someone else in a different state (Texas), reboxed by that person then sent to the original address within the state having the mag cap limit (Maryland). Doing this would be illegal in the state of Maryland as it constitutes a transfer within the state borders of magazines with a capacity of over 10 rounds. It is no different than an online gun shop sending high cap mags to someone Maryland (other than an FFL), it is not lawful.
To be clear, transfer means to buy, sell and gift/give. But, in fact, there’s more to it, I believe the manufacture of mags over 10 rounds is illegal in the state as well.
I cannot legally give my next door neighbor a 30 round AR magazine, if I do I have technically broken the law as that is a transfer within the state borders. If my neighbor and I hop in my car, drive over the Delaware state line, I can then give him that 30 round mag, turn the car around and return to Maryland. Perfectly legal, but absolutely absurd.
The edit I added (which you highlighted in bold) was intended tongue-in-cheek, as people say, “it’s only illegal if you get caught”…
As I remarked previously, it is a foolish ban for a number of reasons:
Mag cap has been shown to have no difference in the outcome of criminal shootings (however that high cap mag might come in handy in a home defense situation, but they do not care about defending yourself in this state, the criminals have more rights than the law abiding citizens in most cases…)
The law as it stands robs Maryland businesses of income and the state of sales tax, they are literally driving commerce out of the state.
