If you are trying to choose a non-lethal way to protect your home in South Africa, you have probably run into four names that keep coming up: the blank gun, the airsoft gun, the paintball marker, and the Byrna launcher. They all look a bit like real firearms, none of them needs a firearm licence, and every shop seems to claim theirs is “the best.” So what is the real difference, and which one actually makes sense for you?
This guide breaks down the blank gun vs airsoft vs paintball question in plain language, adds the Byrna launcher into the mix because so many buyers ask about it, and compares all four the way a normal South African shopper would — on price, on the law, on how they work, and on whether they will actually stop someone breaking into your house.
Let’s get into it.
Quick Answer: Blank Gun vs Airsoft vs Paintball vs Byrna
Before we go deep, here is the short version for people who just want the bottom line:
- A blank gun fires loud blank cartridges (no bullet leaves the barrel). It is built for deterrence — the bang, the muzzle flash, and the realistic look scare an attacker off. Many models also fire pepper cartridges.
- An airsoft gun fires small 6mm plastic BBs. It is built for a sport (military simulation), not self-defence. It barely stings through clothing.
- A paintball marker fires 0.68 calibre paint-filled balls. It is built for the paintball sport, though some people use security rounds for defence.
- A Byrna launcher fires 0.68 calibre kinetic and chemical (pepper/teargas) projectiles using CO2. It is purpose-built as a less-lethal self-defence tool with real stopping power at a distance.
If your goal is home defence on a budget, the blank gun usually wins on price and intimidation. If your goal is recreation, airsoft or paintball is the answer. If you want maximum non-lethal stopping power and have the budget, the Byrna is the premium option. Now let’s see why.
What Is a Blank Gun?
A blank gun, also called a blank-firing pistol, is a non-lethal replica firearm that is chambered for blank cartridges. In South Africa, almost every model you will find is a 9mm P.A.K. replica — meaning it is designed to fire 9x22mm P.A.K. blank rounds and nothing else. The barrel is permanently blocked and unrifled, so no projectile can ever travel down it.
When you pull the trigger, the cartridge produces a loud, sharp report and a bright muzzle flash, the slide cycles back just like a real pistol, and an empty shell ejects. There is recoil, there is smoke, and there is noise — but nothing flies out of the front. That is the whole point. The gun mimics the experience of a real firearm so closely that an intruder cannot tell the difference in the heat of the moment.
The other big advantage in the South African market is versatility: many blank pistols also accept 9mm P.A.K. pepper cartridges, which release a tear gas or pepper irritant at close range. So a single blank gun can give you both an intimidating bang and an irritant payload.
Popular brands locally include Retay, Blow, Kuzey, Zoraki, Ekol, Aksa and Sur Arms. Prices typically run from around R999 for an entry model (like the Sur Arms 2004) up to R2,800–R3,995 for premium Zoraki and Ekol signal pistols, with most popular models sitting in the R1,650 to R2,350 band.
What Is an Airsoft Gun?
An airsoft gun is a replica designed for a recreational shooting sport. It fires 6mm round plastic BBs using spring, gas, or an electric (AEG) system. The guns are full-scale replicas of real-world rifles and pistols, which is exactly why airsoft “milsim” (military simulation) feels so immersive — players run team scenarios that look like real tactical movements.
Here is the key thing for self-defence shoppers: airsoft is built for play, not protection. A 6mm plastic BB weighs almost nothing. It will leave a small welt on bare skin at close range and can sting, but through a jacket it does very little, and it is nowhere near enough to reliably stop a determined attacker. Airsoft also has no loud report and no real intimidation factor compared to a blank gun.
In South Africa, airsoft BBs cost almost nothing (you buy them by the thousand), and the guns range from a couple hundred rand for a basic spring pistol up to R5,000–R7,000+ for high-end AEG rifles. Great fun. Wrong tool for home defence.
What Is a Paintball Marker?
A paintball marker is the gun used in the paintball sport. It fires 0.68 calibre spherical gelatin capsules filled with dye that break on impact, marking the player who has been hit. Markers are powered by CO2 or compressed air (HPA), and a hit genuinely stings — far more than airsoft — which is why some South Africans do consider paintball markers for self-defence using special pepper or hard “security” rounds.
There is a catch, though. A paintball marker is bulky, the air tank needs refilling, and a standard marker isn’t designed or shaped for fast self-defence draw and use. It works for the sport it was built for, and some less-lethal “launcher” versions exist, but for everyday home protection it is awkward compared to a compact blank pistol or a Byrna.
Paintball markers in South Africa start low (entry markers from around R600–R1,500) and climb steeply for tournament-grade gear.
What Is a Byrna Launcher?
The Byrna is the newcomer that has shaken up the South African non-lethal market, and it sits in a different class from the other three. Designed and manufactured in South Africa, the Byrna launcher is powered by compressed CO2 and fires 0.68 calibre kinetic (hard plastic) and chemical-irritant projectiles that can disable a threat from up to roughly 18–20 metres away.
The chemical rounds are the heavy hitters. Byrna’s pepper and teargas projectiles contain a potent blend of OC, CS and PAVA (synthetic pepper) that explodes into a cloud on impact, causing intense tearing, burning skin, coughing and loss of motor control for anywhere between 5 minutes and an hour — long enough to escape and call for help. Projectiles leave the barrel at up to around 90 metres per second.
Because it is not classified as a firearm, no licence, permit or background check is required — you just need to be 18 or older. The trade-off is price. A Byrna SD or HD kit runs roughly R6,500–R7,400, with the Mission 4 rifle reaching R15,000+, and you pay per projectile (kinetic rounds around R39–R49 each, plus CO2 cartridges). It is the most capable, but also by far the most expensive of the four.

How Loud Is a Blank Gun Compared to the Others?
Noise is one of the blank gun’s biggest self-defence advantages, and it is where it crushes airsoft and paintball. A 9mm P.A.K. blank generates roughly 130–140 dB — that is around 80–90% of the sound intensity of a live 9mm round (which sits near 160 dB). An 8mm blank is a little softer at about 120–130 dB.
For comparison, an airsoft gun is almost silent and a paintball marker only produces a moderate “pop.” That loud, unmistakable gunshot report is exactly what makes a blank gun such an effective deterrent — most intruders run the instant they hear what sounds like a real firearm going off. Just remember: at those decibel levels you should always wear hearing protection when practising.
Are They Legal in South Africa?
Good news first: none of these four require a firearm licence in South Africa, because none of them is classified as a firearm under the Firearms Control Act. You simply have to be 18 or older to buy, and retailers will ask for proof of age (and, for blank ammunition, may require your ID for the explosives register).
But “no licence” does not mean “no rules.” All of these devices look like real guns, and that creates legal risk if you misuse them. Under South African law, pointing any of these at a person who genuinely believes it is a real firearm can lead to a charge of “pointing of a firearm” — even though it is technically non-lethal. Carrying an assembled replica around in public, brandishing it, or using it for anything other than lawful self-defence can land you in serious trouble.
The safe rules of thumb: keep your device at home or transport it concealed and unloaded, only ever produce it in a genuine self-defence situation, and never use more force than is reasonable for the threat you are facing. (This is general information, not legal advice — check the current regulations if you are unsure.)
Which One Should You Buy? Choosing by Use Case
The “best” choice depends entirely on what you actually want it for. Here is how to match the tool to the job:
For affordable home defence and deterrence → Blank Gun. It is the cheapest realistic option, the loud report and muzzle flash scare off most intruders, it looks exactly like a real pistol, and many models add a pepper cartridge option. For most South African households on a budget, this is the practical pick.
For recreation and team games → Airsoft or Paintball. If you want a hobby rather than a self-defence tool, these are purpose-built for fun. Airsoft suits realistic milsim scenarios; paintball suits faster, messier team battles.
For maximum non-lethal stopping power → Byrna. If you have the budget and you want genuine ranged stopping power with a pepper cloud that physically incapacitates an attacker (not just scares them), the Byrna is the most capable. It costs several times more than a blank gun, but it does more.
For a woman wanting something compact and simple → Blank Gun or Byrna. Both are light, easy to use, and require no licence. A compact blank pistol is budget-friendly and loud; a Byrna SD has no recoil and real range.
Final Thoughts
When you strip away the marketing, the blank gun vs airsoft vs paintball vs Byrna question comes down to purpose. Airsoft and paintball are sports gear that some people repurpose. The blank gun and the Byrna are the two built specifically for self-defence — the blank gun winning on price and intimidation, the Byrna winning on outright stopping power.
For the average South African who wants a realistic, loud, licence-free deterrent that won’t break the bank, a quality 9mm P.A.K. blank gun from a trusted brand like Retay, Blow, Kuzey or Zoraki remains the most sensible starting point. If you later want to step up to ranged chemical stopping power, the Byrna is there.
Whichever you choose, buy from a reputable South African supplier, stick to the right ammunition for your device, and always handle it responsibly and within the law.
