Firearms regulation in Switzerland allows the acquisition of semi-automatic, and – with a may-issue permit – fully automatic firearms, by Swiss citizens and foreigners with or without permanent residence. The laws pertaining to the acquisition of firearms in Switzerland are amongst the most liberal in the world, as well as being the most permissive in Europe. Swiss gun laws are primarily about the acquisition of arms, and not ownership. As such a license is not required to own a gun by itself, but a shall-issue permit is required to purchase most types of firearms. Bolt-action rifles, break-actions and hunting rifles do not require an acquisition permit, and can be acquired with just a background check. An explicit reason must be submitted to be issued an acquisition permit for handguns or semi-automatics unless the reason is sport-shooting, hunting or collecting. Permits for concealed carrying in public are issued sparingly. The acquisition of fully automatic weapons, suppressors and target lasers requires special permits issued by the cantonal firearms office. Police use of hollow point ammunition is limited to special situations.
The applicable federal legislations are "SR 514.54 Federal Law on Weapons, Weapon Equipment and Ammunition" (, , ) of 20 June 1997 (current edition of 15 August 2019), and "SR 514.541 Ordinance on Weapons, Armament Accessories and Ammunition" (, , ) of 2 July 2008 (current edition of 15 August 2019). The Weapons Law recognises a qualified "right to acquire, possess and carry arms".
Swiss gun culture has emerged from a long tradition of shooting ("tirs"), which served as a formative element of national identity in the post-Napoleonic Restoration of the Confederacy, and the long-standing practice of a militia organization of the Swiss Army in which soldiers' service rifles are usually stored privately at their homes (it became the choice of the soldier in 2010). What started as a gun culture centered around defense of the country through military duty also became a target shooting and collecting one. In addition to this, many cantons (notably the alpine cantons of Grisons and Valais) have strong traditions of hunting (see #Gun culture in Switzerland), accounting for a large but unknown number of privately held hunting rifles, as only weapons acquired since 2008 are registered. However, in a 2019 referendum voters opted to conform with European Union regulations which restrict the acquisition of semi-automatic firearms with high-capacity magazines. A permit for semi-automatic firearms equipped "with" high-capacity magazines is issued to anyone fulfilling article 8 of the Weapons Act under the promise they will show after five and ten years that they are a member of a shooting club, or that they used a firearm at least once a year within that five and ten years period for their first permit of the kind or to weapons collectors. The law on the acquisition of a high-capacity magazine by itself did not change.
Number of guns in circulation.
Switzerland thus has a relatively high gun ownership rate. There are no official statistics, and estimates vary considerably.
The 2017 report from Small Arms Survey has estimated that the number of civilian-held firearms in Switzerland is 2,332,000, which given a population of 8.4 million corresponds to a gun ownership of around 27.6 guns per 100 residents. Other estimates place the number of privately held firearms upwards to a high total of 4,500,000, giving the nation an estimate of 54.5 guns per 100 people in 2017. 
The International Crime Victims Survey conducted in 2004-05 reported that approximately 28.6% of all households in Switzerland owned firearms and 10.3% owned handguns, giving Switzerland the second-highest percentage of firearm ownership in Europe. A recent study by the Zurich University of Applied Sciences released in 2023 revealed that the most commonly owned guns are handguns (caliber ;.22lr) (85%) with semi-automatic rifles in close second (76%). 
When Switzerland joined the Schengen Information System in 2008, it was forced to introduce a registry for firearms, though only those that changed hands since are registered, and no central registry was created. However, multiple proposals have been submitted over the years and most recently, a proposal by Green Party Marionna Schlatter to introduce a central registry was rejected by the Parliament on the 5th of March 2024. Consequently, each canton is still responsible for its registry.
The number of registered firearms in thoses databases was reported as 876,000 as of August 2017 which given a population of 8.4 million corresponds to around 10.3 registered guns per 100 residents.
Regulation.
Switzerland's Weapons Law (WG, LArm) and Weapons Act (WV, OArm) has been revised to accede to the Schengen Treaty effective 12 December 2008, and modified in 2019 after a referendum from the Swiss population to implement the European Firearms Directive which was added in the Schengen agreement. The Act on Personal Military Equipment (VPAA, OEPM) governs the handling of military equipment, and in particular the handling of personal weapons by military personnel.
The law is applied to the following weapons:
Generally prohibited weapons are:
Acquisition.
Buying guns.
In order to purchase most weapons, the purchaser must obtain a weapon acquisition permit (art. 8 WG/LArm). Swiss citizens and foreigners with a C permit over the age of 18 who are not under a curator nor identified as being a danger for themselves or others, and who do not have a criminal record with a conviction for a violent crime or of several convictions as long as they haven't been written out can request such a permit. Foreign nationals who do not have a settlement permit but who are resident in Switzerland must present the competent cantonal authority with an official attestation from their home country confirming they are authorised to acquire the weapon or essential weapon component in that country in order to buy (art. 9a WG/LArm). Foreigners with sole citizenship to the following countries are explicitly excluded from the right to buy, sell and own weapons and their parts unless they ask for an exceptional authorization to the state: Serbia, Bosnia and Herzegovina, Kosovo, North Macedonia, Turkey, Sri Lanka, Algeria and Albania.
The following information must be provided to the cantonal weapon bureau together with the weapon application form (art. 15 WV/OArm):
For each transfer of a weapon or an essential weapon component without a weapons acquisition permit (art. 10 WG/LArm), a written contract must be concluded. Each Party shall keep them for at least ten years. The contract must include the following information (art. 11 WG/LArm):
This information must be sent within 30 days to the cantonal weapon registration bureau, where the weapon holders are registered, though CO2 and airsoft guns are not concerned by this (art. 11 WGLArm)
Categories.
Antique firearms.
The following weapons are governed solely by Articles 27 (carrying) and 28 (transportation) (art. 2 WG/LArm):
No acquisition permit needed.
The following weapons can be acquired without acquisition permits (art. 10 WG/LArm):

Shall-issue exceptional acquisition permit for sport shooters.
The following weapons from the generally prohibited category as well as weapon accessories can be bought with a shall-issue exceptional permit for sport shooter; proof of regular use or membership of a club needs to be provided after 5 and 10 years.

Buying ammunition.
In order to purchase ammunition, the buyer must fulfill the same legal rules that apply when buying guns ;ref name="art. 8 al. 2 WG/LArm" group=note ;buyer must be over the age of 18, not under a curator nor identified as being a danger for themselves or others, and don't have a criminal record with a conviction for a violent crime or of several convictions as long as they haven't been written out. ;/ref ; (art. 15 WG/LArm). Foreigners with sole citizenship to the following countries are explicitly excluded from the right to buy and own ammunition: Serbia, Bosnia and Herzegovina, Kosovo, North Macedonia, Turkey, Sri Lanka, Algeria and Albania.
The buyer must provide the following information to the seller (art. 15, 16 WG/LArm; art. 24 WV/OArm):
However, ammunition can be freely acquired during shooting events and range practice. Any person who has not yet reached the age of 18 may freely acquire ammunition if it is used for shooting immediately and under supervision (art. 16 § 1 &amp; 2 WG/LArm)
The acquisition and possession of the following ammunition is generally prohibited but can be acquired for reasons such as industrial purposes, hunting or collecting (art. 26 WV):
Reloading of ammunition is allowed (art. 19 § 4 WG/LArm) 
While the Swiss Weapons Act and its Ordinance don't limit the quantity of ammunition one can own and store, cantonal ordinances on regulations on preventive fire protection may limit the storage without appropriate paperwork. Zürich, for instance, limits the storage to 300kg of ammunition without permitting from the cantonal fire police (VVB art. F § 17 let. e)
Storage.
Storage of weapons, essential weapon components, ammunition and ammunition components is regulated as follows (art. 26 WG/LArm):
Further requirements are needed in regard to automatic firearms or firearms that have been converted to semi-automatic (art. 47 WV/OArm):
Carrying guns.
To carry a firearm in public or outdoors (and for a militia member to carry a firearm other than his issued weapons while off-duty), a person must have a gun carrying permit (, , ; art. 27 WG/LArm), which in most cases is issued only to private citizens working in occupations such as security. It is, however, quite common to see a person in military service or a sport shooter to be "en route" with his rifle, albeit unloaded. The issue of such exceptional permits is extremely selective (see #Conditions_for_obtaining_a_Carrying_Permit).
However, it is permissible to carry firearms in public or outdoors if the holder (art. 27 § 4 WG/LArm):
Furthermore, any licensed holder of a gun may "transport" an unloaded firearm for special situations (see #Transporting guns).
Conditions for obtaining a Carrying Permit.
There are three conditions (art. 27 § 2 WG/LArm):
The carrying permit remains valid for a term of five years (unless otherwise surrendered or revoked), and applies only to the type of firearm for which the permit was issued. Additional constraints may be invoked to modify any specific permit (art. 27 § 3 WG/LArm).
However, a person who wants to renew his or her firearms license does not need to retake the practical test if the test was passed less than three years ago. They do not need to retake the theory test on the same condition, provided that the legal provisions have not been significantly changed and that there is no doubt that they have sufficient knowledge of the legal conditions for using a weapon (art. 48 § 4 WV/OArm).
Transporting guns.
Guns may be transported in public as long as an appropriate justification is present. This means to transport a gun in public, the following requirements apply (art. 28 WG/LArm):
Army-issued arms and ammunition collection.
The Swiss army has long been a militia trained and structured to rapidly respond against foreign aggression. Swiss males grow up expecting to undergo basic military training, usually at age 20 in the recruit school, the basic-training camp, after which Swiss men remain part of the "militia" in reserve capacity usually until age 30 (age 34 for officers).
Before 2007, members of the Swiss Militia were supplied with 50 rounds of ammunition for their military weapon in a sealed ammo box which was audited by the army during repetition courses (Pocket ammunition). This was so that, in the case of an emergency, the militia could respond quickly.
In December 2007, the Swiss Federal Council decided that the distribution of ammunition to soldiers would stop and
