Navigating California's Latest Firearm Regulations: Derya Arms' Commitment to Compliance and Innovation

November 25, 2025

As we near the end of 2025, the firearms industry in California is adapting to a wave of new regulations designed to enhance public safety while addressing concerns over modifiable weapons and untraceable components. Key legislation signed into law by Governor Gavin Newsom in October 2025 includes Assembly Bill 1127 (AB 1127), Assembly Bill 1263 (AB 1263), and Senate Bill 704 (SB 704). At Derya Arms, we're dedicated to staying ahead of these changes, ensuring our high-quality firearms, parts, and accessories—like our popular DY9 pistols, DY12 shotguns, and precision barrels, grips, and stocks—remain accessible to law-abiding gun owners. While Derya Arms is not an activist company, we proudly contribute to pro-Second Amendment organizations such as the Gun Owners of America (GOA) and others dedicated to protecting these rights. We remain steadfast in our support for the 2A community across every state, complying fully with local laws without making concessions or compromising our principles—unlike some manufacturers who may yield prematurely or collaborate with regulators in ways that undermine the community. Our focus is on delivering reliable products that empower responsible ownership, and we're here to navigate these changes alongside you. In this blog, we'll break down these laws, their implications for shooters, dealers, and manufacturers, and how we're innovating to keep serving the Golden State without compromise.

Understanding the New Laws

AB 1127: Targeting Convertible Semiautomatic Pistols

AB 1127 focuses on firearms that can be easily modified into fully automatic weapons, often called "converter pistols" or "DIY machine guns." Effective July 1, 2026, it prohibits licensed dealers from selling, offering, exchanging, giving, transferring, or delivering semiautomatic pistols that can be readily converted into machine guns via simple devices. This particularly affects striker-fired handguns, leading some to label it a "Glock Ban" due to its impact on models like those from Glock.

Supporters argue it curbs illegal modifications and rapid-fire conversions in communities. For gun owners, this means certain pistols won't be available through dealers after mid-2026 unless redesigned to comply. Importantly, it doesn't affect current ownership—only future dealer transactions. This builds on California's existing roster system, aiming to balance Second Amendment rights with safety.

AB 1263 and SB 704: Regulating Firearm Parts, Accessories, and Barrels

AB 1263 expands oversight on "ghost guns" by regulating "firearm precursor parts" and "firearm-related products," including unfinished frames, receivers, barrels, grips, stocks, flash suppressors, threaded attachments, and even digital files for 3D printing or CNC machining. It aims to prevent untraceable home-assembled firearms through verification and sales restrictions.

SB 704 specifically targets firearm barrels, requiring in-person transactions and background checks to avoid their use in illegal builds.

Key details:

• Affected Items:
  • Parts/Accessories: Grips (pistol, forward, or second-hand), stocks (folding, telescoping, or thumbhole), shrouds, flash suppressors/hiders, and other attachments.
  • Barrels: Standalone or unattached, including threaded ones for pistols or rifles.
  • Note: Magazines follow existing rules (e.g., 10-round limit per Penal Code §32310), with no new changes beyond digital file bans.
• Digital Files: Prohibitions on sharing or selling designs for restricted parts start January 1, 2026.
• Timelines:
  • Through December 31, 2025: No changes—business as usual.
  • January 1, 2026: Enhanced verification (ID checks, acknowledgment forms) for direct shipments of parts and barrels under AB 1263.
  • July 1, 2027: Barrels under SB 704 require in-person handling via licensed California dealers (FFLs) with background checks. Non-barrel parts can continue direct shipping with verification.

These laws exempt complete firearms, attached components, and shipments to law enforcement, military, wholesalers, or FFLs. For more, check the California Legislative Information website or DOJ firearms page.

How These Regulations Affect the Firearms Market

For manufacturers like Derya Arms, these bills add compliance layers in one of the most regulated states. AB 1127 pushes redesigns for non-convertible pistols, while AB 1263 and SB 704 introduce verification for parts to close ghost gun loopholes. Dealers risk penalties for non-compliance, potentially limiting shelf options if companies lag. However, California's roster already demands high standards, and these laws extend that focus.

We've always built reliable, compliant products—like our DY12 shotgun, a favorite for hunters and sport shooters. Now, we're applying that ethos to our pistols, parts, and barrels to maintain performance while meeting new rules.

Derya Arms' Path Forward: Innovation and Continued Support

We're turning these challenges into opportunities, accelerating designs and processes to keep California customers equipped. Here's our plan:

For Pistols Under AB 1127

• Continuing Shipments of the Current DY9 Through 2025: We'll ship our California-compliant DY9—a compact, affordable 9mm—until year's end, giving you time to acquire it under current rules.
• Submitting the Patent-Pending Updated DY9 in Q1 2026: This redesigned version ensures non-convertibility while preserving ergonomics, accuracy, and value. It's our innovative response to AB 1127.
• Introducing the DY9Z for California in Q2 2026: Tailored for the market, we'll submit this enhanced model with anticipated shipments starting July 2026. It builds on our expertise for home defense and range use, at an accessible price.

For Parts, Accessories, and Barrels Under AB 1263 and SB 704

• Continuing Shipments with Minimal Disruption:
  • Parts/Accessories: Direct-to-home shipping continues post-2027, with 2026 verification.
  • Barrels: Direct shipments through June 30, 2027; post that, we'll explore FFL partnerships for pickups. For instance, our DY9 Island upper, which includes a barrel, can be shipped directly to California customers with the required verification form starting January 1, 2026, through June 30, 2027, ensuring compliance while making it accessible.
  • Compliant magazines and unaffected items ship uninterrupted.
• Streamlining Compliance:
  • From January 1, 2026, California orders for regulated items trigger automated verification: Email with e-signable form and secure ID upload (e.g., driver's license for age/address). Reviews in 2 business days, with adult signature required.
  • No added costs—integrated for affordability. Non-CA orders unchanged.
• Expanding Our Lineup:
  • Prioritizing fixed-magazine setups, non-threaded attachments, and serialized parts.
  • Removing restricted digital files, shifting to legal build resources.

Your feedback shapes these efforts, and we're grateful for the CA guns community's support. Just as with the DY12, we're ensuring our DY9 series and components remain safe, superior, and available.
