Price, licence rules, how the gas system works and which CO₂ pistol to buy — from the people who make India's only semi-automatic CO₂ pellet pistol.
Quick answer
A CO₂ air pistol runs on a replaceable 12 g carbon-dioxide cylinder, so it fires semi-automatically with no cocking. In India a .177 CO₂ pistol under 20 joules needs no arms licence, but must be bought from an authorised dealer who records your ID. The Indian-made Camstar Star RX Gen 3 costs ₹25,500; imported Glock replicas cost ₹55,000+.
The Star RX Gen 3 CO₂ pistol plus everything it runs on — 12 g CO₂ cylinders, .177 match pellets and spare magazines. Shipped by the manufacturer with a GST invoice.

Yes — .177 and under 20 joules needs no licence. Rule 84 of the Arms Rules 2016 requires a licence only for air weapons above 20 joules (15 ft-lbs) and/or with a bore larger than .177 inch (4.5 mm). An ordinary .177 CO₂ pistol is below both limits in every state.
No licence does not mean no rules.

Inside a sealed 12 g cartridge the CO₂ sits mostly as liquid with gas above it. Screw the cartridge into the grip and a pin pierces its cap; gas fills a small valve chamber. Each trigger pull lets a hammer knock the valve open for a few milliseconds, and that metered burst pushes the pellet down the rifled barrel. As gas leaves, some liquid boils to replace it, so pressure stays nearly constant until the liquid runs out — which is why CO₂ shot-to-shot consistency is good right up to the last few shots.
Boiling liquid takes heat from the cartridge and the metal around it. Fire a full magazine quickly and the grip chills; colder gas means lower pressure and a slower pellet. Pause 10–15 seconds between shots and the cylinder rewarms.

Short version: buy spring to learn, CO₂ for speed, PCP for group size. New to the sport? A ₹8,400 spring pistol teaches more per rupee than anything else.
At 40 shots per ₹110 cylinder (₹550 per five) the gas costs about ₹2.75 a shot; .177 match pellets add about ₹1.50 (₹450 per tin of 300). Call it ₹4 per trigger pull. Someone shooting 100 pellets a week spends roughly ₹22,000 a year, of which ₹14,000 is gas — over a few years the gas can cost more than the pistol. Worth it if you want semi-automatic practice you cannot get any other way; if not, a spring pistol costs only the pellets. More: 12 g CO₂ cylinders in India · how long a CO₂ cartridge lasts.
This is the question the Khushboo Patani video put in front of millions of people. The honest answer from a manufacturer: a .177 CO₂ pistol is a deterrent and a training tool, not a stopping weapon. It produces a few joules; it can seriously injure an eye but will not reliably stop a determined adult. Its realistic look is what deters — and the same look makes showing it in public a legal risk. Pepper spray, awareness, a charged phone and 112 come first.

The Star RX Gen 3 is India's first semi-automatic CO₂ air pistol: .177 (4.5 mm), single- and double-action, 32 rounds across four 8-shot rotary magazines, about 400 fps with a 0.524 g pellet, full-metal body, illuminated rear sight. It ships with a hard case, holster, two CO₂ cylinders, pellets and a cleaning rod, carries a 12-month manufacturing warranty and is built and serviced in Lucknow.

The Indian-made Camstar Star RX Gen 3 CO₂ semi-automatic pistol costs ₹25,500 delivered (premium colours ₹26,500), the lowest price for a semi-automatic CO₂ pellet pistol in India. Imported CO₂ pistols cost more after duty: the Umarex Glock 17 Gen 4 BB pistol — the model in Khushboo Patani’s viral video — is listed at roughly ₹55,000–85,000, and imported Beretta, Walther and Glock replicas generally start around ₹35,000–45,000. Running cost is about ₹3–4 per shot for gas and pellets.
Yes, if it is .177 calibre (4.5 mm) and produces under 20 joules of muzzle energy. Rule 84 of the Arms Rules 2016 requires a licence only for air weapons above 20 joules and/or with a bore over .177 inch, so an ordinary .177 CO₂ pistol needs no arms licence. It is still regulated: it must be bought from an authorised or licensed dealer who records your ID and address, the buyer must be an adult, and using or brandishing it against a person can be a criminal offence under the Bharatiya Nyaya Sanhita.
A CO₂ air pistol is an air pistol powered by a small cylinder of liquefied carbon dioxide, usually 12 grams. Piercing the cylinder releases gas at a steady pressure, and each trigger pull meters a dose behind the pellet. Because the gas does the work there is no spring to cock between shots, which is what allows a CO₂ pistol to be semi-automatic.
For most Indian buyers, the Camstar Star RX Gen 3 (₹25,500): it is the only semi-automatic CO₂ pellet pistol made in India, full-metal, with 32 rounds across four 8-shot rotary magazines, about 400 fps, a 12-month warranty serviced from Lucknow, and spares sold individually. If you specifically want a licensed Glock or Beretta replica with a blowback slide, an imported Umarex model is the alternative, at two to three times the price and with dealer-dependent service.
Only as a deterrent, never as a stopping weapon. A .177 CO₂ pistol produces a few joules — a 9 mm firearm produces around 500 — so it will not reliably stop a determined attacker. Its realistic value is that it looks and handles like a real pistol, which deters many opportunistic threats, and that it builds handling skill. Showing or pointing a realistic pistol to frighten someone can itself be criminal intimidation under the BNS, so keep it at home or out of sight.
About 30 to 60 shots, depending on temperature and pace. Warm weather and a 10–15 second pause between shots give the top of that range; a cold north-Indian winter morning or rapid fire gives the bottom, because expanding gas chills the cylinder and lowers its pressure. A five-pack of 12 g cylinders is ₹550 on camstarsports.com.
Buy spring to learn, CO₂ for speed. A spring pistol (Star Leo ₹8,400, Mauser X ₹9,499) needs cocking every shot, costs nothing to run beyond pellets and teaches a deliberate routine. A CO₂ pistol like the Star RX Gen 3 fires as fast as you can aim with negligible recoil, which suits trigger-reset and rapid-fire drills, but it needs gas and loses some velocity in cold weather.
Yes, from a seller who is authorised to sell air weapons and verifies your identity. Camstar is the manufacturer (Capital Airgun Manufacturers Pvt Ltd, Lucknow) and ships pan-India with a GST invoice, ID verification, a 12-month warranty and cash-on-delivery options; you can also buy through a Camstar dealer if you would rather see the gun first. Avoid any seller who does not ask for ID or will not give a GST invoice.
Yes — it is the one real drawback of the system. CO₂ pressure depends on temperature, so on a cold morning each shot is slower. The effect is mild in most of India for most of the year and noticeable in a Delhi or Lucknow winter. Spring and PCP airguns are unaffected.
Yes — a .177 (4.5 mm) Glock-style CO₂ air pistol under 20 joules needs no arms licence, unlike a real 9 mm Glock, which is prohibited bore. The Umarex Glock 17 Gen 4 (the pistol in Khushboo Patani’s video) is an imported BB replica at about ₹55,000–85,000; the Indian-made Camstar Star RX Gen 3 is a semi-auto pellet pistol at ₹25,500. Buy from a licensed dealer with ID, and keep it cased in public.
Remove the CO₂ cartridge after each session and dry-fire once to vent residual gas — leaving a pierced cartridge in place holds the face seal under constant pressure and causes slow leaks. Store the pistol unloaded, locked, dry and away from children, with a light film of oil on exposed metal in the monsoon.
Spring and CO₂, ₹8,400 to ₹25,500.
