Ghost guns are illegal. If you want to build a homemade firearm, you need to get a state serial number (de facto registration) and pass a background check.  As of July 1, 2024, all “weapons precursors” must be sold through a licensed dealer.  You can carry as many pistols as you like, as long as they are handguns and they are all within the calibre limit. There is no limit to the number of pistols allowed. The bull judge is another strange weapon that is technically legal, although it can fire a shotgun grenade. California residents who purchase long guns in other states are subject to the same requirements as for purchasing firearms in the state if the purchaser returns to California with the guns in their possession. For example, a California resident who purchases a long gun in Nevada would have to go through a Nevada-registered FFL for the gun to be delivered to an EFL in California, which would then complete the DROS and manage the 10-day waiting period. However, a California resident is not subject to California law for long guns purchased out-of-state and never brought into California. In other words, a California resident who buys a long gun in Nevada and keeps it in the home of a family member or friend in Nevada would not be violating California law until the gun enters the state. This would also be the case for a California resident who purchases a California-defined assault weapon in another state where such weapons are legal, and the weapon is never brought into California. The California Department of Justice is known to conduct stabbing operations by sending undercover agents to gun stores and gun shows in neighboring states to watch California residents buy guns at those locations, and then track buyers in California. where they are then arrested and prosecuted.
 Differences in gun laws and gun control philosophies between California and neighboring states have been a source of heated controversy among political figures in California, who tend to support strict restrictions on gun ownership and use. and politicians in Arizona and Nevada, who primarily defend individual gun rights.  Even some guns that are treated as conventional firearms under federal law are illegal in California. For example, the Thompson Contender single-shot pistol, when equipped or possessed with a .45 Colt/.410 shotgun barrel combination or simply the barrel itself, and the popular Taurus Judge.45 Colt/.410 shotgun revolvers are illegal in California because they are considered short-barreled shotguns. However, the ATF does not consider them to be sawed-off shotguns, as their barrels are rifled rather than smooth holes. According to the same ATF letter, these launchers, whether armed only with pyrotechnics (e.g., “bird bombs” or “Star Burst distress torches”) or tear gas canisters, are neither weapons nor destructive devices (and are therefore not subject to federal jurisdiction). The potential “legal trap” is that possession of these 37mm launchers with only pyrotechnic cartridges led to charges in California. What for? California gun owners who found these goods acceptable because they could obtain them from commercial sources were prosecuted by aggressive district prosecutors who used the broad definitions of destructive devices and fireworks. The open carrying of firearms in California is governed by a number of laws that sometimes conflict with each other. This has led to considerable confusion about the legality of open port in the state. The open carrying of loaded or unloaded firearms in public is generally prohibited, although open carrying may be permitted in unincorporated rural areas where permitted by local ordinance, and elsewhere in certain circumstances. Although the shotgun grenade is accepted by the bull judge, it is not prohibited.
Weapons such as sawed-off shotguns, short-barreled shotguns and other similar weapons are now banned. Everything related to actions will almost always be prohibited. Sword sticks and blackjacks are examples of gunless weapons that are illegal under SDA and Oklahoma law. On June 29, 2017, a federal judge blocked the enforcement of the ban on major magazine ownership in Proposition 63 pending the outcome of a legal battle over the ban. Journals that would have been subject to the Proposition 63 ban may be lawfully retained by individuals until the injunction is lifted and/or the ban is upheld by the courts.   On 29. In March 2019, the entire Major Magazine Act was permanently blocked by the District Court; These include the prohibition of possession, as well as the prohibition of manufacture, import, sale, etc., Following a stay request by the Attorney General, Judge Benitez authorized the enforcement of the ban on the manufacture, import, and sale of major magazines, while upholding the injunction against the enforcement of the previously legal large shipper possession ban. Including all purchases made between the effective date of the court order, March 29, 2019, and April 5, 2019, at 5:00 p.m.  The HQ DOJ subsequently prepared a Ferranto Commission report announcing that this list would be updated in early 2006; as of December 2006, it had not done so.
1. In February 2006, the DOJ Board also issued a controversial memorandum on the subject; Critics say the acts described are not legally justified or supported by §§ 12275-12290 of the Penal Code. This note states that once firearms are declared and registered as assault weapons outside the list, they will not be able to add distinctive features or remove solid magazines. This is disputed by pro-gun groups because there is no criminal violation in the California Criminal Code to add or alter features to a legally acquired and registered assault weapon. There are protections under the federal Gun Owner Protection Act for non-residents traveling to California with firearms that meet the state`s criteria for assault weapons. First, the weapon must be legal for the traveler under federal law and the laws of their home state and destination state. In addition, the weapon in question must be unloaded with the firearm and ammunition, which are locked in separate suitcases, and placed in an area of the vehicle that is not easily accessible, such as in the trunk of a car or in the back of a truck. After all, the traveler should cross the state by the shortest route, which makes the minimum number of stops achievable. This is an OC Armory Judge AOW 3″ stainless steel pistol. A standard Taurus judge is illegal in the state of California because the penal code considers any pistol that can fire a solid shotgun grenade to be a short-barreled shotgun (SBS). Because the judge has a barrel fired and should fire shotgun ammunition, he only came to the state of California to legal trouble. Although it is not considered a “short-barreled shotgun” under federal law, it has been classified as such under state law.
Because California law is much more explicit regarding shotguns, including a firearm designed or redesigned to fire a fixed shotgun cartridge and has a barrel length of less than eighteen inches, the judge was classified as a short-barreled shotgun. The purchase of handguns, with the exception of private transfers and holders of certificates of eligibility, is limited to one per 30-day period. To purchase a handgun, a purchaser must have a handgun safety certificate.  This is achieved by passing a written exam conducted by a Department of Justice certified instructor on the safe and legal use of small arms. The certificate is valid for five years. A purchaser must also demonstrate safe handling when taking possession of a handgun. Certain individuals are exempt from security certificate and tamper demonstration requirements, including active and retired military and law enforcement personnel, hunter safety certificate holders, and illegal driver`s licence holders.  As of July 1, 2021, the purchase of medium-fire semi-automatic rifles will also be limited to one per 30-day period.  Although the Federal Bureau of Alcohol, Tobacco, Firearms, and Explosives (“ATF”) considers an item not subject to federal law to be a firearm, California law may make it illegal. What for?
