Suppressor Laws in California – Legal Requirements & How to Buy
If you are asking “are suppressors legal in California?” the short answer is no. Civilian ownership of suppressors (also known as silencers) is currently banned under California law. However, that may not always be the case. Ongoing legal challenges, including the Sanchez v. Bonta lawsuit, are actively pushing to overturn the state’s suppressor ban and restore Second Amendment protections for Californians.
Silencer Shop proudly supports these efforts, advocating for the legalization of suppressors in California. This guide covers the current suppressor laws in California, explains the legal barriers in place, outlines what is possible for out-of-state ownership, and shows how Silencer Shop is helping lead the fight.
Is It Legal to Own a Suppressor in California?
No, suppressors are not legal for civilian ownership in California. The state explicitly bans the possession, sale, and use of silencers, regardless of federal approval or NFA compliance.
Under California Penal Code §33410, only specific law enforcement personnel, licensed dealers with the correct endorsements, and military agencies can legally possess suppressors in the state.
If a civilian is found in possession of a suppressor in California, it can result in felony charges. Violations of §33410 carry penalties of up to three years in state prison. Even though silencers are legal federally under the National Firearms Act (NFA) and in 42 other states, California law overrides that federal allowance within state borders.

Sanchez v. Bonta and the Fight for Suppressor Rights
The Sanchez v. Bonta lawsuit is the most significant active legal challenge to California’s suppressor ban. The case argues that the ban violates Second Amendment protections under the framework established by recent Supreme Court precedent. Oral arguments were heard by the Ninth Circuit in November 2025, and the case remains pending.
At the federal level, recent legislation has eliminated the $200 NFA tax stamp fee for suppressors, making ownership more accessible in the 42 states where they are legal. These changes underscore the growing momentum toward suppressor normalization nationwide, even as California maintains its ban.

Suppressor Trusts in California
An NFA trust in California can still be legally created and maintained, but it does not override state restrictions on suppressor possession. While some California residents use an NFA trust to purchase suppressors for out-of-state use or business ownership, no trust can legally own or store a suppressor inside California.
