A bill meant to ban guns manufactured through 3-D printers is expected to be tweaked after concerns were raised it would cover too many firearms as initially written.

“There were some technicalities on one and really needing to have a better definition and understanding on the other,” Senate Majority Leader Andrea Stewart-Cousins said at a press conference on Tuesday. “We want to move things out quickly, especially things that have been hanging around for a long time, but we want to do it right.”

The bill sought to restrict the possession of so-called “ghost guns” and require firearms have “each major component” be detectable by a metal detector.

Components of many modern-day firearms, like grips, are made of plastic.

“The guns used to be all made of steel with plastic grips,” said Tom King of the New York Rifle And Pistol Association. “But people wanted lighter guns to carry around. I don’t think there’s a manufacturer out there who doesn’t make one.”

King estimated this would cover about “80 percent” of legal guns in circulation.

The Democratic-led Legislature on Tuesday approved a package of gun control bills that included a ban on teachers and non-police officers from possessing guns on school grounds, an extension of the waiting period to 30 days as well as a “red flag” bill that restricts the possession of guns for people who are deemed to be too dangerous. Lawmakers also approved a bill requiring the State Police administer a gun buyback program.
