In explaining his plan to ban “high-capacity magazines,” Biden also talks about hunting. “Federal law prevents hunters from hunting migratory game birds with more than three shells in their shotgun,” his campaign says. “That means our federal law does more to protect ducks than children.”
The three-round limit suggested by that non sequitur would be clearly unconstitutional, effectively banning all semi-automatic firearms and revolvers. But judging from an expired federal law that Biden supported, he would be more generous, allowing magazines with capacities of up to 10 rounds—the same as the limit set by California, which made it a crime to manufacture, transfer, or even possess “large-capacity magazines” (LCMs).
As the 9th Circuit noted, that law covered half of the magazines owned by Americans—115 million out of 230 million, according to one estimate. LCMs come standard with some of the most popular firearms sold in the United States, including “Glocks, Berettas, and other handguns that are staples of self-defense.”
