Year of the Glock 2026!

The serial number plate is permanently embedded in the polymer. The two I sent back had a crack/break in the polymer and were unusable, there'd be no way to fix or replace something like that once they're banned.
sure but how much of that serial number plate needs to be on a new frame you build?

As far as I know, that plate belongs to that frame, they cannot just pop the plate out and stick it in a new frame and call it good. I believe that would be considered tampering with a serial number, which is a no no for ATF.

So say you have a Springfield echelon "Central Operating group" and you modify it so that you are only using the rails of the control group and every part interior are changed. I don't think that would be illegal, would it? the only part you are saving is the part with the serial number. The Federal rule about modifying the serial number talks about "removing, defacing, modifying, etc." not taking the small amount of your firearm that is left that you would like to repair into a working firearm. Say you have an ex that's also really good with machine tools and she cuts your 1911 in half. Would it be illegal to take the portion with the serial number and rebuild that with new metal into a working frame?
 
Who knows? The only way to find is if there's precedent set. If you want to be that guy, take your chances. I assume most of the rest of us have better things to do, and a new gun is a F- of a lot cheaper than a lawyer.

Well I was trying to ask if anyone knows, not if anyone doesn't know ;) The answer could have a lot of interesting repercussions for those of us that like pistols that aren't the boring horse💩 on the roster

That's different, those parts are not a permanent piece of the serialized frame. The serial plate in a Glock frame IS a permanent part of the frame. What you are suggesting would be the equivalent of cutting off the part of a 1911 frame with the serial number and welding it onto a different frame. At that point, you are destroying a serialized frame and assigning that same serial number to a new gun, which they cannot do. What would realistically happen is Glock would stop working on guns from California, or at the very least they would refuse warranty work on anything that would require a replacement frame. As of right now, there's no way around that.
 
those of us that like pistols that aren't the boring horse💩 on the roster

Gen 6 Glocks getting on the roster won't help us get any interesting guns tho, unfortunately.

Part of me still hopes we'll see a CZ Shadow 2 Carry, or hell any CZ at this point, but I don't have high hopes. I could see FN maybe adding some of their striker pistols, but we'll see.

gen 6 is the unicorn right now because people assume its going to be some game changer. But reality its just a gen 5+ lol. people out there really paying too much for them

Gen 6 is actually the first Glock I liked the feel of, mainly just due to the more aggressive grip texture and lack of finger grooves. That said, no way is it worth even half of what people are selling them for here. For $600 or less, sure, for $1800? They must be smoking the good stuff.

OH believe me I do not disagree. I'm just brainstorming what someone with a broken pistol frame could do to repair their already registered firearm into something that works, and something that would be way better than a Glock.

I'm thinking less about what Glock would do and more about what anyone could do with a broken serialized frame or receiver. The new rules that ATF put out regarding the definitions of a firearm as a result of the supreme court ruling on ghost guns is actually kind of interesting.

Realistically for us here in Cali, your options are pretty much wall hanger or gun buy back. California has it's own laws surrounding "ghost guns" and all that, so I'm assuming the new ATF rules really won't affect us here much.

I think the law is clear in the case of the 1911. The damaged gun can be repaired by a licensed gunsmith (FFL-07) if its structurally restorable...if your ex is licensed to manufacture guns, that works too. If the gunsmith cant repair it, they need to properly destroyed and have the destruction documented.

For FCUs, the frame is the firearm — the stainless steel chassis that bears the serial number. Modify that and you are breaking the law, everything surrounding it is a non-serialized part and making changes are legal.

they both matter, Fed and State because they define things differently and you have to pass both checks. To be clear I'm not talking about manufacturing a firearm I'm talking about fixing and existing one and how much of the original frame needs to be involved.

And actually that specific federal definition was adopted into our state code. I actually misspoke when I said they made the definition per the supreme court case, they made the definition in 2022 and it was upheld by the SC with Vanderstok

Cal. Code Regs. Tit. 11, § 4303​

(a) For purposes of this chapter, the following definitions apply:
(1) "Federally regulated firearm precursor part" means any firearm precursor part deemed to be a firearm pursuant to Chapter 44 (commencing with Section 921) of Title 18 of the United States Code and regulations issued pursuant thereto, and, if required, has been imprinted with a serial number by a federal licensee authorized to serialize firearms in compliance with all applicable federal laws and regulations. (Pen. Code, § 16519.) As of August 24, 2022, the "regulations issued pursuant thereto" are sections 478.11 and 478.12 of Title 27 of the Code of Federal Regulations (August 2022), hereby incorporated by reference.
(2) "Firearm precursor part" means any forging, casting, printing, extrusion, machined body or similar article:
(A) that has reached a stage in manufacture where it may readily be completed, assembled or converted to be used as the frame or receiver of a functional firearm; or
(B) that is marketed or sold to the public to become or be used as the frame or receiver of a functional firearm once completed, assembled or converted.

"Firearm precursor part" does not include firearm parts that can only be used on antique firearms, as defined in Penal Code section 16170, subdivision (c).
(3) "Frame" means the part of a handgun, or variants thereof, that provides housing or a structure for the primary energized component designed to hold back the hammer, striker, bolt, or similar component prior to initiation of the firing sequence (i.e., sear or equivalent), even if pins or other attachments are required to connect such component to the housing or structure.

For a split or multiple part frame design, "frame" instead means the part of a handgun, or variants thereof, that has been designated as the frame by the federal Bureau of Alcohol, Tobacco, Firearms, and Explosives in subdivision (f)(1) of section 478.12 of Title 27 of the Code of Federal Regulations (August 2022), hereby incorporated by reference. One example includes the Ruger Mark IV pistol, in which the frame is the upper part of the weapon that provides housing for the bolt or breechblock.
(4) "Machining" means the process of cutting, drilling, shaping, indexing, milling, or removing material from a forging, casting, printing, extrusion, or similar article using a tool or equipment.
(5) "Readily" means a process, action, or physical state that is fairly or reasonably efficient, quick, and easy, but not necessarily the most efficient, speediest, or easiest process, action, or physical state. With respect to the classification of firearm precursor parts, factors relevant in making this determination include the following:
(A) Time, i.e., how long it takes to finish the process;
(B) Ease, i.e., how difficult it is to do so;
(C) Expertise, i.e., what knowledge and skills are required;
(D) Equipment, i.e., what tools are required;
(E) Parts availability, i.e., whether additional parts are required, and how easily they can be obtained;
(F) Expense, i.e., how much it costs;
(G) Scope, i.e., the extent to which the subject of the process must be changed to finish it; and
(H) Feasibility, i.e., whether the process would damage or destroy the subject of the process, or cause it to malfunction.

In determining whether a forging, casting, printing, extrusion, machined body, or similar article has reached a stage in manufacture where it may readily be completed, assembled, or converted to be used as the frame or receiver of a functional firearm, the Department may consider any available instructions, guides, templates, jigs, equipment, tools, or marketing materials.
(6) "Receiver" means the part of a rifle, shotgun, or projectile weapon other than a handgun, or variants thereof, that provides housing or a structure for the primary component designed to block or seal the breech prior to initiation of the firing sequence (i.e., bolt, breechblock, or equivalent), even if pins or other attachments are required to connect such component to the housing or structure.

For a split or multiple part receiver design, "receiver" instead means the part of a rifle, shotgun, or projectile weapon other than a handgun, or variants thereof, that has been designated as the receiver by the federal Bureau of Alcohol, Tobacco, Firearms, and Explosives in subdivision (f)(1) of section 478.12 of Title 27 of the Code of Federal Regulations (August 2022), hereby incorporated by reference. Some examples include the following:
(1) for AR-15/M16 variant firearms, the receiver is the lower part of the weapon that provides housing for the trigger mechanism and hammer (i.e. lower receiver);
(2) for a Benelli 121 M1 Shotgun, the receiver is the lower part of the weapon that provides housing for the trigger mechanism; and
(3) for Vickers/Maxim, Browning 1919, M2, and box-type machineguns and semiautomatic variants, the receiver is the side plate of the weapon that is designed to hold the charging handle.
(7) "Variant" and "variants thereof" mean a weapon utilizing a similar frame or receiver design irrespective of new or different model designations or configurations, characteristics, features, components, accessories, or attachments. For example, an AK-type firearm with a short stock and a pistol grip is a pistol variant of an AK-type rifle, an AR-type firearm with a short stock and a pistol grip is a pistol variant of an AR-type rifle, and a revolving cylinder shotgun is a shotgun variant of a revolver.
 
which law is that that says it has to be repaired by a gunsmith? And what law says you can't modify the serial bearing part as long as you aren't destroying identifying information

man you are in DEEP grey territory - its interesting, and TBH, Im probably going to burn through my Claude credit pool out of curiosity.

Its interesting the response - I went back and forth with it for a bit, largely introducing your ideas, here is where it landed (note the ending with Claude keeping it real):

The federal principle supports your reading — theoretically

Under the ATF framework, if the serialized component survives intact and legible, federal law's position has been that rebuilding around it is repair. The ATF Rule 2021R-05F points in that direction.

But your scenario exposes the real limits of that principle:

On a Glock, the serial number is on a small metal rail plate embedded in the polymer frame — it is not itself a structural component capable of independently functioning as a frame. This creates a problem the ATF framework doesn't cleanly resolve: there's a meaningful difference between a damaged serialized receiver that retains structural integrity as a foundation versus a bare serial number plate with no remaining structural function whatsoever.

ATF has specifically addressed torch-cut and severely damaged receivers in several technical letters — and the position has generally been that a receiver reduced to a non-structural fragment is considered destroyed, not repairable. The serial number's legibility is necessary but not sufficient — the component also needs to retain enough structural identity to serve as the foundation for reconstruction rather than merely serving as a source of identification numbers.

If only the serial plate survives, rebuilding a complete Glock frame around it is functionally identical to creating a new gun. ATF would likely characterize that as manufacturing, not repair, because the structural foundation of the regulated component no longer exists.

The California layer compounds it

Even if the federal repair argument were viable, California PC 29180 requires that any firearm manufactured in California — including personally manufactured firearms — be serialized through DOJ before completion. If ATF characterized your rebuild as manufacturing, California's law independently requires DOJ serialization of the new component regardless of what serial plate you retained from the original.

The honest bottom line

Your scenario sits in genuinely unresolved territory where the theoretical federal repair framework collides with the physical reality of what survived. A fragment that is exclusively an identifier with no remaining structural function as a frame is a much weaker basis for a repair claim than a damaged but structurally present receiver. This is precisely the kind of edge case that warrants a California firearms attorney and potentially a direct ATF technical letter before proceeding — not because the answer is definitely no, but because the consequences of being wrong are federal felony exposure and I cannot tell you the answer is definitively yes.

Man, yeah AI is f'd. Federally you can "self make" firearms without even having to serialize them. So if you are starting from a block of metal you can make a frame/receiver/etc and legally make a "ghost gun" with no serial number. I believe that "claude" also made an assumption on "torch cut and severely damaged receivers" because there is guidance on torch cutting from the ATF but it's guidance on what constitutes destruction, not construction. either way, yes it's complex and I'm not trying to do it I'm just interested in what the limits of the law are. It does seem like something that hasn't been tested, hell I've been looking online for like a whole hour and haven't found any case law so.... ha
 
That’s what I’m worried about. I just bought a new gen 6 and I’m not sure what would happen if I needed it repaired/replaced 😬
Has anyone ever cracked a stock pistol frame? Some folks have gotten 200,000 rounds through Glocks and 100,000 rounds through CZ’s. PX4’s as well. If your off roster pistol frame cracks, you may just have to buy another. Them’s the breaks. You’ll spend more on ammo trying to wear them out than buying a new one.
