In Singapore, the laws surrounding weapons are taken very seriously, with strict regulations in place to maintain public safety. Whether it’s a prohibited weapon, a replica weapon, or a weapon used for self-defence, each category is governed by its own set of laws, and breaching these can lead to severe consequences.
Understanding the prohibited, replica and self-defence weapons is crucial for anyone living in or visiting Singapore, as even seemingly harmless items can be classified as illegal weapons under certain circumstances.
In this blog, we’ll break down these categories of weapons, what the law says about them, and the penalties associated with violating these laws.
Prohibited Weapons in Singapore
In Singapore, certain weapons are strictly prohibited due to their potential danger to public safety. These weapons are regulated under the Weapons Act and include items that can be used for criminal purposes, particularly those capable of causing harm or injury.
Here are the key points to know:
-
- Firearms and Ammunition: Firearms, such as guns and rifles, are strictly prohibited without a valid licence. Possessing or trafficking in firearms and ammunition without proper authorisation can result in severe legal consequences.
- Explosives and Explosive Materials: The possession, manufacture, or sale of explosives, including items like grenades or bombs, is banned. This also extends to certain chemicals that could be used to create explosives.
- Flick Knives and Switchblades: Flick knives, which open automatically by the push of a button, and switchblades are considered illegal under the Weapons Act. These types of knives are seen as particularly dangerous due to their ease of use and concealability.
- Other Prohibited Weapons:
-
- Zombie knives, brass knuckles, stun guns, and taser guns are prohibited for civilian use in Singapore.
- Machetes, swords, and other large bladed weapons may also fall under restrictions if they’re deemed to be used as weapons rather than for legitimate purposes (e.g., farming or sporting).
Replica Weapons and Their Legal Status

Replica weapons are items designed to look like real firearms, knives, or other dangerous objects but are incapable of causing harm or firing projectiles. Although they are not functional weapons, their legal status is subject to regulation in Singapore due to their potential to cause alarm or be mistaken for real weapons.
Here are the main points:
- Legal Classification of Replica Weapons:
- Replicas of firearms, knives, or other dangerous weapons are considered prohibited if they can reasonably be mistaken for the real thing, even if they are not capable of causing harm.
For example, replica guns that closely resemble actual firearms may be restricted, particularly if they are used or displayed in public places.
- Possession and Display:
- Public Display: Displaying replica weapons in public or using them in public spaces can lead to legal consequences if they cause panic or alarm among the public.
- Private Ownership: Owning a replica weapon for personal collection or display may be legal, but it is advisable to check the specific regulations and ensure the weapon does not resemble a real firearm or pose any safety risks.
- Penalties for Unlawful Possession or Use:
- Possession of a replica weapon without a legitimate reason (such as for a movie or theatrical production) can result in criminal charges.
- The Court will consider the context in which the replica weapon is used or displayed, and it can lead to fines, imprisonment, or both.
Penalties for Violating Weapon Laws

Violating weapon laws in Singapore, whether it involves prohibited weapons or the unlawful possession of replica or self-defence weapons, carries severe penalties. These laws are in place to ensure public safety and deter the use of dangerous weapons for criminal activity.
The penalties are structured as follows:
- Prohibited Weapons:
- Firearms and Ammunition:
- Individuals found guilty of possessing firearms or ammunition without a valid licence can face up to 10 years in prison and/or a fine of up to $20,000.
- Trafficking or importing firearms or explosives can result in life imprisonment or death, especially if the offence involves a firearm that is used in a crime.
- Other Prohibited Weapons:
- Possession of knives, zombie knives, brass knuckles, and other prohibited weapons may result in a fine of up to $5,000 and/or up to 3 years in prison.
- Firearms and Ammunition:
- Replica Weapons:
- Possession: If a replica weapon is possessed unlawfully, an individual can face up to 3 years in prison or a fine, or both, depending on the severity of the situation.
- Use or Display: Using or displaying a replica weapon in a public space where it causes public fear or alarm can lead to similar penalties.
- Self-Defence Weapons:
- Carrying a self-defence weapon such as pepper spray, a stun gun, or a baton is not necessarily illegal, but doing so without a valid reason or using excessive force can result in fines, imprisonment, or both.
- The right to self-defence in a non-defensive situation or excessively in response to a minor threat could lead to charges of assault, and the penalties can be severe, depending on the injury caused to the other person.
- General Weapon-Related Offences:
- If an individual is caught committing any weapon-related offences, especially those involving prohibited or dangerous weapons, the Court may impose a sentence based on the gravity of the offence, prior criminal record, and the intent behind possessing or using the weapon.
