The Kimber PepperBlaster II is a non-lethal personal defense device designed for civilians and professionals seeking an effective alternative to traditional pepper spray.
Instead of using aerosol propellant, it employs a pyrotechnic power system to launch two separate Oleoresin Capsicum (OC) gel charges at approximately 112 mph (180 km/h), reaching targets up to 13 feet (4 meters) away. Each discharge releases a powerful 10% OC concentration (2.4% major capsaicinoids), far stronger than most commercial sprays.
The device weighs just 4.2 ounces, measures 4.5 inches long, and has a four-year shelf life thanks to its sealed, non-pressurized design. Compact, water-resistant, and simple to use, the PepperBlaster II is engineered for maximum reliability and minimal blowback, making it one of the most innovative less-lethal tools available today.
What is the Kimber PepperBlaster II and why is it different from traditional pepper spray?
The Kimber PepperBlaster II isn’t your average canister of pepper spray — it’s a self-defense tool engineered like a firearm, designed to solve the limitations of conventional sprays. Introduced in the early 2010s, it was developed in collaboration with JPX of Switzerland and marketed by Kimber Manufacturing, a brand best known for its premium 1911 handguns.
Unlike aerosol-based sprays that rely on compressed gas, the PepperBlaster II uses a pyrotechnic piston system to propel its OC gel. This means it doesn’t lose pressure over time, functions in extreme weather, and provides consistent velocity with every shot. The gel delivery also minimizes mist and airborne contamination — critical in indoor or windy conditions where traditional sprays can backfire.
The PepperBlaster II is aimed at civilians, joggers, commuters, and security professionals who want an easily concealable defensive option that delivers reliable, directional stopping power without the risks of lethal force.

How is the Kimber PepperBlaster II designed and built?
Construction and Materials
The PepperBlaster II is built with high-strength polymer housing, engineered for durability and light weight. Its sealed pyrotechnic firing mechanism ensures consistent propulsion, unaffected by altitude or temperature. The OC cartridges are loaded into twin barrels positioned vertically, allowing two independent discharges with separate trigger pulls.
The trigger guard flips down during use, preventing accidental activation while maintaining intuitive access. Each shot is powered by a non-reloadable propellant charge, meaning the entire unit is disposable after both rounds are fired.
Ergonomics and Handling
The PepperBlaster II’s shape resembles a small handgun, making it instinctive for firearm users to point and aim. The grip contours and finger grooves fit naturally in the hand, while the centerline sights allow precise targeting at short distances. Its light 4-ounce weight makes it ideal for purse, pocket, or belt carry.
The safety mechanism is purely mechanical — no switches or toggles. Lifting the trigger guard readies the device instantly. This simple yet deliberate design balances speed and safety, ensuring it won’t discharge in a bag or pocket accidentally.
What variants of the Kimber PepperBlaster II are available?
Kimber offers two main versions of the PepperBlaster II, plus a training model.
Standard Kimber PepperBlaster II
Available in red or gray, the standard version includes two live OC charges in a sealed unit. It’s compact, weather-resistant, and disposable after use.
Kimber PepperBlaster II Trainer
Distinguished by a blue housing, this inert version fires harmless dye to simulate real-world use. It’s perfect for training users on grip, trigger pull, and aiming without expending live OC.
Comparisons with Other Products
When compared to common sprays like Sabre Red, Fox Labs, or Mace Gel, the PepperBlaster II stands apart with:
-
Double the effective range
-
Near-instant discharge velocity (no aerosol drift)
-
Two discrete, semi-automatic shots
-
No aerosol pressure loss over time
“It’s more like a two-shot shotgun of OC gel,” remarked a reviewer on Reddit CCW. “You get pinpoint accuracy and instant incapacitation without clouding yourself.”
Unlike many aerosol sprays that canister-leak or expire early, the PepperBlaster II maintains full potency and reliability for its entire four-year shelf life.
How does the Kimber PepperBlaster II perform in real-world use?
Accuracy and Target Control
The PepperBlaster II’s pyrotechnic piston propulsion gives it exceptional consistency. It launches a focused jet of OC gel that hits targets up to 13 feet away with minimal spread. At close distances (under 8 feet), accuracy is nearly pinpoint — allowing precise targeting of the face or upper chest.
The design nearly eliminates cross-contamination or wind drift, a major advantage in confined spaces like vehicles, hallways, or elevators.
Reaction and Effectiveness
The OC formula delivers a rapid incapacitating effect, causing involuntary eye closure, intense burning sensations, and temporary respiratory distress. Effects typically last 30–45 minutes, providing ample time for escape or law enforcement response.
Reliability
Because it’s non-pressurized, the PepperBlaster II performs reliably in extreme temperatures and at high altitudes. There’s no valve, propellant, or nozzle to clog. Both shots fire consistently and independently with identical velocity.
Limitations
The most common critique is the two-shot limitation. Once fired twice, the device is expended and must be replaced. However, this is considered a reasonable trade-off for its compact size and performance consistency.
What kind of ammunition or OC solution does the PepperBlaster II use?
The PepperBlaster II’s “ammunition” consists of two sealed OC gel cartridges, each loaded with:
-
10% Oleoresin Capsicum (OC)
-
2.4% major capsaicinoids, far exceeding common civilian sprays (typically 1.3%)
This potent formula creates an adhesive gel that sticks to skin, eyes, and mucous membranes upon impact, ensuring long-lasting incapacitation. Unlike aerosols, it won’t disperse into the air or contaminate surroundings.
Because the cartridges are sealed and integral to the device, they are not reloadable. When both shots are fired, the PepperBlaster II should be replaced entirely.
How practical is the Kimber PepperBlaster II for different uses?
Concealed and Everyday Carry
The PepperBlaster II is ideal for pocket or purse carry. It fits easily into compact spaces, weighs less than most smartphones, and can be drawn and fired in seconds. For non-firearm carriers, it’s one of the most discreet and effective self-defense tools available.
Home and Vehicle Defense
Its gel delivery system makes it safe for use indoors or inside vehicles without creating lingering airborne contamination. It’s a smart addition to home safety kits or car compartments for non-lethal defense.
Professional and Outdoor Use
Security personnel, delivery drivers, and outdoor enthusiasts appreciate its weather-resistant design and instant reliability. It can be used in rain, wind, or extreme temperatures without risk of malfunction.
What are the best holsters for the Kimber PepperBlaster II?
The Kimber PepperBlaster II holster selection allows for secure, comfortable carry in any situation. Each model is made from durable Boltaron polymer for precise retention and flexibility in different carry setups.
OWB Paddle Holster
Offers quick attachment and removal, perfect for range training or professionals who alternate between carry positions.
