SACRAMENTO (CBS/AP) – A California lawmaker has said he will introduce legislation aimed at strengthening the state’s restrictions on gun ownership in the wake of the mass shooting at an elementary school in Newtown, Conn.

Sen. Leland Yee, a San Francisco Democrat, said Monday that he will try again to close the so-called “bullet button” loophole in the state’s assault weapons ban, which allows manufacturers to sell weapons with magazines that can be replaced quickly using a simple button.

Yee said he is also exploring legislation on everything from background checks to gun storage.

A similar “bullet button” bill Yee introduced in the wake of the massacre in Aurora, Colo., died in the state Assembly.
