In California, it is legal to possess a handgun with a pistol grip. However, there are some restrictions on how the gun may be transported and what type of ammunition it can use. A person must also have a valid license to carry a gun in public.
Pistol grips became legal in California after a ruling by the Ninth Circuit Court of Appeals in 2014. In that case, the court ruled that a ban on semi-automatic rifles with pistol grips was unconstitutional. However, the court did uphold other restrictions on how such guns could be carried and used.
Since then, there have been several changes to the laws governing firearms in California. For example, in 2017, a new law went into effect that requires all gun owners to safely store their firearms. This law was prompted by a series of mass shootings in the state, including the 2016 shooting in San Bernardino that left 14 people dead.
It is important to note that gun laws can change at any time. Therefore, it is always best to check with local law enforcement or an attorney before carrying a gun in public.
