WASHINGTON — Sen. Charles Schumer yesterday slammed a Republican plan that would allow out-of-state gun carriers with concealed-carry permits to bring their weapons into New York.

Republicans are trying to make concealed-gun reciprocity among the states an amendment to Senate gun-control legislation that will be brought up for long-awaited debate tomorrow.

“This amendment would open the floodgates to guns across New York City, and there is nothing the NYPD or other law enforcement can do about it,” said Schumer (D-NY). “It would turn Times Square into the OK Corral.”

New York state requires higher standards for conceal permits than do federal laws and other states, Schumer said.
