When You Want More Than a Keychain Spray
Most pepper sprays top out at 10-12 feet and require decent aim under pressure. The Pepper Gun 2.0 gives you 20 feet and a pistol-style grip that makes it easier to aim like you would any point-and-shoot device. If you want more standoff distance and a more intuitive shooting platform, this is a step up from the pocket-carry options.
The refillable cartridge system is also worth noting — when it’s empty, you swap the cartridge rather than buying a whole new unit. The water practice cartridge lets you actually practice your draw and aim before you ever load a live cartridge. That’s a genuinely useful feature that most sprays don’t offer.
Who This Pepper Gun Is For
This one makes sense for someone who keeps it in a nightstand, a vehicle, or a bag they don’t mind carrying something a bit larger in. At 8.25″ long and 1.25 lbs, it’s not a keychain item — it’s more like a home defense or vehicle carry option.
People who live alone, or who want something more capable for their home than a small canister, tend to gravitate toward this. It’s also popular with people who’ve had training with firearms and like the familiar grip-and-trigger interface, even if the mechanics are completely different.
If you just need something on your keychain for a walk to the parking garage, one of the smaller Mace models is probably more practical. But if you want real standoff distance and a dedicated carry option, this is a legitimate step up.
Is This the Right Choice for You?
Choose the Mace Pepper Gun 2.0 if you want:
- Maximum range — 20 feet is significantly farther than standard sprays
- A refillable platform you can train with using the included water cartridge
- Built-in lighting for low-visibility situations
Consider something else if you need:
- Something compact enough for a keychain or small purse
- Fewer moving parts — cartridge swaps add a step standard sprays don’t have
How It Works
The Pepper Gun operates on a trigger system with a slide-release safety switch. Pull the trigger once to activate the steady LED flashlight. Pull again for the strobe. When you’re ready to spray, the OC cartridge delivers a powerful stream up to 20 feet. The design allows the canister to spray from any angle — right-side up, sideways, or inverted — which eliminates the orientation problem that trips people up with standard canisters.
The OC formula is the same pepper spray compound Mace uses across their line — causes immediate eye closure, coughing, choking, and intense burning on contact. At 7 one-second bursts per cartridge, you’re not going to get dozens of uses out of one cartridge, but seven bursts at 20 feet is substantially more usable than a keychain canister in a serious situation.
The integrated Picatinny rail on the bottom lets you add accessories like a laser sight if you want. The 3 LR44 batteries that power the LED are included.

Safety is a slide-release switch. One-year warranty on canister and nozzle. Replacement OC and water cartridges available separately.
If you want more range and a more deliberate platform than a pocket spray, the Pepper Gun 2.0 is a solid, refillable option — and the water cartridge means you can actually practice with it.
Frequently Asked Questions
How hard is it to swap the cartridges?
It’s designed to be straightforward — the cartridges snap in and out without tools. Mace designed the refill system specifically for easy field replacement. That said, it’s worth practicing the swap with the water cartridge before you ever need to do it in a stressful situation. Muscle memory matters here.
What does “sprays from any angle” actually mean?
Standard aerosol canisters have a dip tube that draws formula from the bottom. If you tilt them past a certain angle, you get propellant instead of formula. The Pepper Gun’s cartridge system is designed to spray regardless of orientation — upright, sideways, even upside-down. In a high-stress situation where you’re not thinking about technique, that can matter.
Is 7 bursts enough?
For one encounter, yes. Most defensive uses of pepper spray involve 1-3 bursts. Seven one-second bursts at 20 feet gives you more than enough for the situation. When a cartridge is used, replacement cartridges are available separately — including the dual pack that comes with both an OC and a water cartridge.
Does the LED strobe actually help in a confrontation?
The strobe can cause disorientation and momentary vision disruption in bright conditions — it’s a genuine tool, not just a feature checkbox. More practically, the steady flashlight mode is useful for identifying what’s actually in front of you in a dark parking lot or hallway before reaching for the trigger. That matters as much as anything else.
