Democrats' plan for gun control is a throwback to 1994's failed "assault weapons" ban, which now includes a limit on high-capacity magazines.
Second amendment opponents argue there is no reason anyone outside the military needs a gun magazine that holds more than 10 rounds. However, those who currently own them would be grandfathered in.
Police agencies say enforcement against person-to-person sales would be virtually impossible.
“There would be millions of them out there, so I don't see how you would ever control that,” says Lenny Miller at Hog Heaven Houston.
Miller says a lot of people use these magazines for sport. Others just because they own them. And he argues banning them will not stop someone from shooting up a grocery store.
“Even if you to 10 or 20, or whatever makes you comfortable, it takes only a split second to pop one out and put another one in,” he says.
Gun control advocates argue it could at least give shooting victims a moment to run, possibly saving lives.
