Governor Newsom signed AB-1263, affecting sales and shipping of Firearm Acessories*, 3D printer code distribution, etc.

**Update 11/4/2025:** For some reason people have been landing on this thread for AB-1263. You should instead be going to the [New Gun Law Practical Overview thread](https://www.reddit.com/r/CAguns/comments/1oew6g5/ca_2025_new_gun_law_practical_overview/) which discusses AB-1263 in easy to read language and breaks down the "firearm accessories" definition into easy to digest parts. The [older more complete analysis thread](https://www.reddit.com/r/CAguns/comments/1jk7xhq/ab1263_hindering_shippingsales_of_pistol_grips/) is still generally true and especially relevant for the other restrictions re: 3D printing and the like.

--- Just a quick legislative update:

[AB-1263](https://leginfo.legislature.ca.gov/faces/billTextClient.xhtml?bill_id=202520260AB1263) was part of the [bills that Governor Newsom signed into law on Saturday, 10-11-2025](https://www.gov.ca.gov/2025/10/11/governor-newsom-issues-legislative-update-10-11-25/).

I already did a [thread with an extensive analysis on this bill](https://www.reddit.com/r/CAguns/comments/1jk7xhq/ab1263_hindering_shippingsales_of_pistol_grips/), so I'll just copy the TL;DR from that.

> ***Firearm Accessory and Gun Barrel sales will require the following:*** Identity + Age Verification (likely via ID/Driver's License), A notice (that purchaser verifies they've recieved and understood) of illegal acts you're not allowed to do. If these items are shipped, address must match the address used for Identity + Age Verification and must be shipped w/ Adult Signature Verification. *A bunch of retailers, especially smaller ones, are going to likely stop shipping to California, and if they do, it will be more expensive.*

> ***What is a Firearm Accessory? It's definitely:*** Pistol Grips, Thumbhole Stocks, Folding or Telescoping Stocks, Grenade Launchers or Flare Launchers, Flash Suppressors, Forward Pistol Grips, Threaded handgun barrels, second handgun handgrips, handgun shrouds, folding/telescoping shotgun stocks, and any other accessories from [CA PC 30515](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=PEN&sectionNum=30515.).

> ***A Firearm Accessory is also probably:*** Fixed Magazine compliance devices like AR MAGLOCK, kingpin, CompMag, etc. Might also be things like speedloaders and MA Loader.

> Also if anyone gets injured/killed by these items the bill opens up a direct path to civil suits against the "firearm industry members" responsible for selling/manufacturing/importing/marketing/wholesaling the item in question.

> And then bill does more stuff: bans more CNC/CAD/3D printer firearm (and accessory) code distribution, holds websites hosting (and people distributing) those things liable to civil suits and civil fines, tries to ban more CNC/3D Printers related to firearm accessory manufacturing... I really have to emphasize there's a lot of stuff here so that's why it's hard to summarize with a single tagline, other than "Here's a huge pile of crap from Mike Gipson".

The bit on Gun Barrels is a bit less important with the signing of [SB-704](https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=202520260SB704), but I expect the defined firearm accessories will see more difficulty being shipped to California in the new year.. ***This will go into effect starting 1/1/2026***. We'll also need to wait for additional regulations to be promulgated by the CA DOJ to further define certain parts of this law.

Once again, [this thread](https://www.reddit.com/r/CAguns/comments/1jk7xhq/ab1263_hindering_shippingsales_of_pistol_grips/) goes into extensive detail if you have any more questions.

I'll see if I find some time next week to do an overview thread of new gun laws passed.
