Mayor Bloomberg’s plan to slash fees for pistol permits is facing a blaze of opposition in the City Council, with many members saying the move is a misfire for one of the nation’s leading voices against gun violence, The Post has learned.

Bloomberg is pushing a council bill — introduced at his request by Public Safety Committee Chairman Peter Vallone (D-Queens) — that would cut the $340 price for original or renewal applications to between $25 and $110, depending on the type of permit.

During a closed-door caucus meeting of about 15 Democratic members of the council yesterday, roughly 10 lawmakers voiced objections to the measure, several sources said.

“There’s no way I could vote on this. Since I’ve been in the council, we’ve voted on numerous bills where fees and fines were increased and it would send a strange message to New Yorkers that the one fine we look to reduce is the fee and fine to permit a gun,” Councilman Erik Dilan (D-Brooklyn), who did not attend the caucus, said.

City Hall sources said the bill, which seems to undercut one of the mayor’s signature causes, is intended to avoid legal battles.

“The National Rifle Association is very good, and we don’t want to open ourselves up needlessly to legal challenge,” one source said.

But Dilan called that rationale “very questionable.”

“I don’t know how anybody could . . . speculate that we’re going to be sued by the National Rifle Association or any other entity for the fee when it’s been set at that rate for several years,” he said.

Council members are scheduled to meet today with city Criminal Justice Coordinator John Feinblatt, who will try to persuade them to support the bill, sources said.

Bloomberg announced in May his proposal to decrease fees as part of a broader plan to ease the city’s gun-application process.

He also announced that the NYPD would accept credit cards for renewal fees and post applications online.

The announcement was seen as a response to the 2008 Supreme Court ruling that struck down parts of the gun-control law in Washington, DC, and other legal challenges to gun laws elsewhere in the country.

“This bill cuts red tape without reducing our ability to keep guns out of the hands of criminals,” Bloomberg spokesman Jason Post said.
