(NBC NEWS) A handful of pro-gun Democrats showed signs of willingness to consider strengthening regulations on firearms in the aftermath of last week’s elementary school shooting in Newtown, Conn.

But that might not mean anything without the cooperation of Republicans, whose senior leaders and rank-and-file members have been mute about their interest in cooperating in a legislative effort to curb gun violence, making the prospects for any new, federal gun law unclear.

After President Barack Obama vowed at a vigil Sunday evening in Newtown to lead “an effort aimed at preventing more tragedies like this,” several Democrats with long track records of supporting gun rights said they would be willing to consider new proposals, like renewing the ban on assault weapons or limiting the capacity of ammunition magazines that are available for sale.
