Gov. Dannel Malloy on Thursday signed a bill that will ban all bump stock-type devices in Connecticut by Oct. 1.

The bipartisan bill will make it illegal to own, sell, transfer or use bump stocks and similar devices.

"The devices that turn semi-automatic weapons into the equivalent of automatic weapons, something that our country banned in the 1930s, is appropriate for that step to be taken in our state," the governor said.

Malloy had been pushing for the ban since he proposed it in January. The bill signing was held at Bulkeley High School in Hartford.

Malloy says he signed the bill at a high school because of the way students nationwide have been outspoken against gun violence.

Anyone caught with a bump stock after the law goes into effect could be charged with a felony. There is a one-year grace period for gun permit owners, who could face a misdemeanor.

More than 20 states have introduced legislation to ban bump stock-type devices following the mass shooting in Las Vegas, where 58 people were killed and hundreds more were injured by a gunman who used the devices.
