Duration: 6:42

California's SB452, enacted in 2023, is set to effectively ban the sale of new semi-automatic handguns in the state starting January 1, 2028. This is due to new microstamping requirements, which the California Department of Justice has deemed technologically viable. The law mandates that all semi-automatic handguns sold by licensed dealers must be "Micro Stamp enabled," a technology not currently widespread or available in the industry, thus impacting the existing firearm roster.

Quick Summary

California's SB452 law, effective January 1, 2028, requires all semi-automatic handguns sold in the state to be 'Micro Stamp enabled.' The California DOJ has deemed this technology viable, but its lack of widespread industry adoption means this effectively bans the sale of new semi-automatic handguns, impacting the existing firearm roster.

Frequently Asked Questions

What is California's SB452 law and when does it take effect?

California's SB452, signed in 2023, mandates that all semi-automatic handguns sold by licensed dealers must be 'Micro Stamp enabled' starting January 1, 2028. This law effectively bans the sale of new semi-automatic handguns that do not feature this technology.

What is firearm microstamping technology?

Firearm microstamping technology imprints a unique, microscopic array of characters, known as a micro stamp, onto spent cartridge cases. This is achieved through a specially designed firing pin installed in the firearm.

How does SB452 impact the California firearm roster?

SB452's microstamping requirement means that any semi-automatic handgun not equipped with this technology cannot be sold or transferred in California after January 1, 2028. Since most, if not all, firearms currently on the roster lack microstamping, it will effectively remove them from sale.

Has the California DOJ deemed microstamping viable?

Yes, the California Department of Justice, under Attorney General Rob Bonta, has released a report concluding that firearm microstamping technology is technologically viable for imprinting micro stamps on spent cartridge cases.
