Threaded barrel

[jeff.i.thomas]

Are threaded barrels legal in California? I'm trying to find some documentation that says they are or are not but can't seem to find anything.

I was talking to a group of guys and one had a comp on his glock. That sparked a debate about the legality of it and more specifically the threaded barrel.

Links and/or penal code numbers would be preferred if they exist.

Thanks much.

In order for a semi-auto Glock pistol to legally have a threaded barrel in CA...
Option A. It is a Registered Assault Weapon (RAW).
Option B. It has a fixed 10 round magazine that can not be removed without removing the slide from the frame or that is permannently attached in the grip.
Option C. A muzzle device is permannetly attached to the threaded barrel.
Option D. The threaded barrel has the threads removed.

California Code of Regulations Title 11 Divison 5 Chapter 39 Article 2 Section 5471
(rr) “Threaded barrel, capable of accepting a flash suppressor, forward handgrip, or silencer” means a threaded barrel able to accept a flash suppressor, forward handgrip, or silencer, and includes a threaded barrel with any one of those features already mounted on it. Some firearms have “lugs” in lieu of threads on the end of the barrel. These lugs are used to attach some versions of silencers. For purposes of this definition a lugged barrel is the same as a threaded barrel.

...Threaded barrel installed on a semi-auto pistol that does not have a fixed magazine = CA illegal assault weapon. [PC 30515(a)(4)(A)]

I knew you'd come through! Almost asked the question to you directly tbh.

So just to be clear, based on that and the specific scenario I mentioned, it would appear that a Glock being a simi-auto pistol without a fixed magazine is illegal in California if it has a threaded barrel as California considers that to be an assault weapon.

Correct.

Only exemptions to this are...
... the Glock is a RAW.
... the muzzle device is permanently attached on the threaded barrel installed on the Glock.

Permanent methods of attachment include full-fusion gas or electric steel-seam welding, high-temperature (1100o F) silver soldering, or blind pinning with the pin head welded over.

Thanks for the info...it's much appreciated.

Is it legal to own a threaded barrel that is NOT INSTALLED on a pistol?

Yes.

However, various CA firearms lawyers have advised that it is prudent to not store or transport a threaded barrel with a semi-auto pistol that does not have a fixed magazine. This is due to past cases involving arrests & convictions for possessing a "broken" assault weapon and for "intent to make/possess" an assault weapon.

Guess then I will take my own advice and turn the threaded end off, or send the barrel to a friend in a state where it is legal.
