PHILADELPHIA (AP) — A gun-rights group is challenging a recent New Jersey law that strengthens a state ban on large-capacity magazines. A law passed this year limits most gun owners to magazines that hold 10 rounds of ammunition instead of the 15-round limit in place since 1990. The Association of New Jersey Rifle and Pistol Clubs, in federal appeals court arguments Tuesday in Philadelphia, says the new law hurts only homeowners because criminals won’t follow it. The New Jersey Attorney General’s Office says 10 rounds are enough for self-defense. Assistant Attorney General Jeremy Feigenbaum says mass shooters might be interrupted if they have to reload after 10 rounds. About seven states, the District of Columbia and several cities have limits on large-capacity magazines. The gun-rights group calls New Jersey’s lower limit an undue burden.
