The sale of handguns is not only legal — it is constitutionally protected. The First Amendment protects truthful, nonmisleading commercial speech promoting lawful products or services, but especially when the products or services are themselves protected by other constitutional rights, such as the right to abortion or the right to buy contraceptives. What is true for unenumerated constitutional rights must be at least as true for the enumerated right to bear arms, which includes the right to possess and acquire handguns.
Plaintiff firearms dealers are therefore constitutionally entitled to convey truthful commercial information about handguns to the public, and the public has a corresponding interest in receiving that information. This includes plaintiffs’ right to advertise their products on-site — an especially useful form of advertising for sellers and consumers alike. Yet California Penal Code § 26820 (“Section 26820”) prevents a firearms dealer from displaying any “handgun or imitation handgun, or [a] placard advertising the sale or other transfer thereof” anywhere that can be seen outside the four corners of its store. Section 26820 thus unconstitutionally prevents firearms dealers from advertising even the most basic commercial information — “Handguns for Sale” — at their places of business.
The government’s defense of Section 26820 would presumably rest on one of two theories. First, the government might argue that some people find handgun advertising offensive, and do not wish to see it in public places. But that “advertisements” might be “offensive … to those exposed to them” is “classically not [a] justification validating the suppression of expression protected by the First Amendment,” including advertising. Carey, 431 U.S. at 701. And the Court has “specifically declined to recognize a distinction between commercial and noncommercial speech that would render [the] interest [in preventing offense to viewers] a sufficient justification for a prohibition of commercial speech.” Bolger, 463 U.S. at 71-72.
Second, the government might argue that it wants to decrease handgun ownership, presumably on the theory that this will decrease violence or injury. But even if decreasing handgun ownership is a permissible justification for government regulations following Heller, it cannot justify this speech restriction. Even if California believes that buying a handgun is a bad decision, “the ‘fear that people would make bad decisions if given truthful information’ cannot justify content-based burdens on speech.” Sorrell v. IMS Health Inc., 564 U.S. ___, 131 S. Ct. 2653, 2670-71 (2011) (citation omitted). The Supreme Court has “rejected the notion that the Government has an interest in preventing the dissemination of truthful commercial information in order to prevent members of the public from making bad decisions with the information.” Thompson v. Western States Medical Center, 535 U.S. 357, 374 (2002).
“The choice ‘between the dangers of suppressing information, and the dangers of its misuse if it is freely available’ is one that ‘the First Amendment makes for us.’” Sorrell, 131 S. Ct. at 2671 (citation omitted). So long as responsible, law-abiding adults may purchase handguns in California, the First Amendment prevents the State from enforcing Section 26820’s ban on on-site handgun advertising.
 See Bigelow v. Virginia, 421 U.S. 809, 822 (1975) (striking down ban on abortion advertisements, partly because “the activity advertised pertained to constitutional interests,” citing Roe v. Wade, 410 U.S. 113 (1973)); Carey v. Population Servs. Int’l, 431 U.S. 678, 700-01 (1977) (striking down ban on contraceptive advertisements, partly because “the information suppressed by this statute ‘related to activity with which, at least in some respects, the State could not interfere’” (citation omitted)); Bolger v. Youngs Drug Prods., 463 U.S. 60, 69 (1983) (striking down ban on mailing contraceptive advertisements, partly because “advertising for contraceptives … relates to activity which is protected from unwarranted state interference”).
 The ability to obtain a handgun is central to a citizen’s ability to exercise the core guarantee secured by the Second Amendment: “the right of law-abiding, responsible citizens to use arms in defense of hearth and home.” District of Columbia v. Heller, 554 U.S. 570, 635 (2008); see id. at 628 (handguns are the “class of ‘arms’” “overwhelmingly chosen by American society for [the] lawful purpose [of self-defense]”); id. at 628-29 (handguns are “the most preferred firearm in the nation to ‘keep’ and use for protection of one’s home and family.”).
