(CNN) - New Jersey Gov. Chris Christie wouldn't say Tuesday whether he'd sign a bill moving through the state legislature that would toughen the state's gun laws.
He was asked by a caller to his monthly "Ask the Governor" program on New Jersey 101.5 about his stance on the measure proposing to reduce the capacity of ammunition magazines that gun owners are permitted to carry.
Christie said he would review whatever final version of the bill that reaches his desk.
"I can't tell you what I'm going to do with the bill until that bill hits my desk," he said. "I'm not going to prejudge anything."
The state Senate voted Tuesday to approve the bill, which now heads back to the Assembly with changes. If finalized, it will be sent to Christie's desk where he'll have 45 days to decide whether to sign it.
Christie, who's one of several Republicans considering running for president in 2016, has been accused by some conservatives of being too moderate on certain issues.
Pressed about his stance on gun control, independent of the pending bill, Christie pivoted back to the New Jersey legislation.
"When it comes to my desk, I will make a decision."
