Legal position by country

Every country has its own rules. For each, this shows how its firearms law classifies the item — with the wording, the legal reference and when it was checked. What applies in a given case depends on the country, the permits held and the gun.

prohibited
Possession is prohibited; at most an individual exemption from a central authority remains.
only with a permit or exemption
Allowed with a firearms licence, for certain purposes (such as hunting or sport) or with an official exemption — the wording says which.
not covered by firearms law
The country’s firearms act does not mention the item (for magazines: below the limit). Hunting, state or provincial law may still regulate it.
not surveyed
There is no checked statement for this country. That is not a clearance.

United States (federal law) only with a permit or exemption

Under federal law a suppressor is a firearm that must be registered (26 U.S.C. § 5845(a)(7)): acquisition only with an approved application and entry in the federal registry; possession without registration is a crime (26 U.S.C. § 5861(d)). State law differs – some states prohibit possession.

Canada prohibited

Every suppressor is a prohibited device (Criminal Code s. 84(1)). Possession without a licence is an offence, and the law provides such a licence only for businesses (Criminal Code s. 92(2); Firearms Act s. 11).

Other countries

Germany only with a permit or exemption

A suppressor is treated like the weapon it is intended for (WaffG Anl. 1 Abschn. 1 UA 1 Nr. 1.3): permit required for a weapon that requires a permit, no permit for a permit-free one. For hunters, the acquisition rules for hunting weapons apply accordingly; they may only use it with long guns approved for hunting that fire centrefire cartridges, when hunting and in hunting practice shooting (WaffG § 13 Abs. 9). The act has no specific rule for sport shooters; a permit requires a need, which the approved rulebooks usually do not establish.

Austria only with a permit or exemption

Suppressors are prohibited, even without a weapon (§ 17 Abs. 1 Z 5 WaffG 1996). Exempt are holders of a valid hunting card who hunt regularly (§ 17 Abs. 3b WaffG 1996); if the hunting card ends, the suppressor must be handed to an authorised person within six months. Sport shooters are not exempt – for them only an exemption permit from the authority remains.

Switzerland only with a permit or exemption

Suppressors are weapon accessories: acquisition and transfer are prohibited (Art. 4 Abs. 2 lit. a, Art. 5 Abs. 2 lit. d WG); the canton may grant an exemption for legitimate reasons (Art. 28b WG). The law names e.g. professional needs, physical disability and collecting – not hunting or sport, but the list is not exhaustive. Since 1 February 2025 the federal hunting ordinance no longer lists the suppressor among prohibited hunting aids; the canton may still prohibit it for hunting. Anyone who acquired one lawfully may keep it.

Legal reference: Art. 4 Abs. 2 lit. a, Art. 5 Abs. 2 lit. d WG; Art. 28b WG · Checked 09/2026 · No guarantee – WG and your authority decide.

Poland only with a permit or exemption

A permit for a weapon fitted with or adapted for a suppressor is only issued for hunting (art. 10 ust. 5 pkt 3 uoBiA) – and even then it may only be used for a sanitary cull ordered by the authority (art. 10 ust. 5a uoBiA). Sport, collector and protection permits do not cover it. Whether the suppressor alone may be acquired is not regulated by the law; this is disputed.

Legal reference: art. 10 ust. 5 pkt 3 uoBiA; art. 10 ust. 5a uoBiA · Checked 09/2026 · No guarantee – uoBiA and your authority decide.

Czechia only with a permit or exemption

Suppressors are subject to the rules for category R4 weapons (§ 9 odst. 4 z. č. 90/2024 Sb.): handling only with a firearms authorisation or firearms licence; the law does not require a particular purpose.

Estonia only with a permit or exemption

The right to own a suppressor comes with the weapons permit (RelvS § 20¹ lg 3). It may only be fitted and used at a shooting range, a shooting ground, when hunting and in the further cases the law refers to there; on a long gun registered for hunting or sport it may stay fitted as long as the gun is only carried there (RelvS § 20¹ lg 3¹).

Lithuania only with a permit or exemption

Suppressors may only be acquired, owned and used by holders of a weapons permit for sport, hunting, service in the Riflemen's Union or soldiers' training (GŠKĮ 13 str. 11 d.); otherwise they are prohibited (GŠKĮ 7 str. 3 d. 6 p.). A permit for self-defence or collecting is not enough.

Finland only with a permit or exemption

A suppressor requires a permit (ampuma-aselaki 3 §, 18 §). Anyone holding a permit to possess a firearm needs no separate permit to acquire, own or transfer one (ampuma-aselaki 19 § 1 mom. 3 k.).

Italy prohibited

Manufacture, import and sale of suppressors are only permitted for the armed forces, state corps or export (art. 2, secondo comma, L. 110/1975); hunting with a suppressed firearm is prohibited (art. 21 co. 1 lett. u) L. 157/1992). Possession of an existing suppressor is not expressly regulated by the provision.
