Connecticut, the site of the massacre that killed 26 staff and children at a local elementary school in December, has become the third state to pass new gun-control legislation in the aftermath of the killings.

The contentious debate in the state ended late Tuesday with the passage of some of the strictest gun laws in the nation (the state already had some of the toughest laws on the books). Connecticut joins New York and Colorado, the site of the 2012 Aurora movie theater shootings, in passing new legislation before Congress takes up its own bill.

The Post's Ed O'Keefe recaps over at The Fix just what the Connecticut bill would do:

The Nutmeg State’s gun laws are now some of the strictest in the nation, as state lawmakers approved a series of changes, including new restrictions on weapons and large capacity ammunition magazines.

The state’s assault weapons ban — already one of the most aggressive nationwide — is being updated to include 100 newer weapons and related parts. It is a more comprehensive ban than most because it lists specific makes and models and only requires a weapon to have one specifically-banned characteristic. Owners of the banned weapons may keep them, but must register with the state.

The law also requires people convicted of certain gun crimes to register with the state, a program similar to the registration of sex offenders. These provisions mirror a similar law passed in New York City in 2006.
