I could not find any information on the legality of suppressors in CA, if they were ever legal. The current Penal Code section 33410 is about suppressors, which was previously section 12500 before the Penal Code was reorganized in 2010. The notation listed in the old section 12500 says that section was amended in 1990, but I couldn't find any language in the 1989 AW ban nor the subsequent feature ban in 1990 that introduced the silencer ban. I've searched various wiki such as the Calgun one but none of them mentions when suppressors get banned in CA. Does anyone know the answer?
Edit: answer is Dangerous Weapons Control Law (1953)
