(CNN) A series of new firearm laws go into effect in Texas on Sunday, just hours after a shooting left seven people dead in the western part of the state.

The laws will further loosen gun restrictions in a state that's had four of the 10 deadliest mass shootings in modern US history, including the El Paso shooting last month, when a gunman stormed a Walmart and killed 22 people.
