NY Gov. Andrew Cuomo, the governor who looks like a secret super villain, signed a landmark gun control law in January that nearly made criminals out of cops and limited ammunition magazines to a capacity that doesn’t exist. Now the governor seeks to undo what he done did in haste and stupidity.

The gun-control law, approved in January, banned the sale of magazines that hold more than seven rounds of ammunition. But, Mr. Cuomo said Wednesday, seven-round magazines are not widely manufactured. And, although the new gun law provided an exemption for the use of 10-round magazines at firing ranges and competitions, it did not provide a legal way for gun owners to purchase such magazines.

As a result, he said, he and legislative leaders were negotiating language that would continue to allow the sale of magazines holding up to 10 rounds, but still forbid New Yorkers from loading more than 7 rounds into those magazines.

“There is no such thing as a seven-bullet magazine,” Mr. Cuomo said at a news conference. “That doesn’t exist. So you really have no practical option.”

So, even under the revision, New Yorkers could own a 10-round magazine…they just couldn’t put 10 rounds into it.

Criminals all over the state will be sure to abide by that.
