What’s up with threaded handgun barrels?

Not Legal. Threaded barrel on a handgun makes it an AW.

I just mind my own business.

They're perfectly legal to own.

Use them all you want on a revolver, or a semi-auto with a fixed magazine.

Use them on a semi-auto with a detachable magazine (including rimfire) and you're created an Assault Weapon.

100% Legal to buy, sell and own in California.

Installing one on your pistol, not so legal. ☹️

You don't know what his credentials are. People always give me weird looks when I'm out testing and demo'ing various silencers.

A threaded barrel with a muzzle device that is permanently attached to the barrel, causes the barrel to no longer be considered a threaded barrel.
^Per CA DOJ BOF, if a CA LE forensic/gun unit can remove the muzzle device that was affixed in a manner that does not meet the CA regulations for permanently attachment [11 CCR 5471(d)], then it will be treated as a threaded barrel.

*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.

Exactly why I don’t even take my RAWs out anymore. Have some 19 year old come tell me why my guns are evil and illegal. Or, my favorite, some dude who’s been into guns for a whopping 2 years tell me I can’t own what I have. Lol

Meh. I don't hesitate to run my RAWs at public ranges or my silencers. (I do bring the paperwork for the silencers just in case)

Threaded barrel on a handgun makes it an AW.

Not a problem if you registered the handgun as an AW during one of the openings.
