Practice First, Carry Live
Here’s the thing about self-defense tools — they only work if you know how to use them. The OC/Water dual pack lets you practice with the water cartridge until you’re comfortable with the Pepper Gun’s trigger, aim, and stream trajectory. Then you load the live OC cartridge and carry with confidence. It’s the training-first approach, and it makes a real difference when the stakes are real.
Who This Refill Is For
This is for Pepper Gun owners who want to stay sharp or who want a fresh live cartridge with the option to keep training. Maybe you used the original practice cartridge and want more reps. Maybe you’re giving the Pepper Gun to someone as a gift and want them to have both training and live ammunition. Maybe your OC cartridge is expired and you figure you might as well practice while you’re reloading. Whatever the scenario, one of each gives you flexibility.
Is This the Right Choice for You?
Choose the OC/Water Dual Pack if you want:
- A practice cartridge to keep building accuracy
- A fresh live OC cartridge for actual carry
- The best combo for someone new to the Pepper Gun
Consider something else if you need:
- Two live OC cartridges without a practice round (get the Dual OC Refill)
- The Pepper Gun itself (this is refills only)
Why Practice Cartridges Matter
Most people never practice with their pepper spray. They buy it, stick it somewhere, and hope they’ll figure it out if the time comes. The Pepper Gun’s water cartridge lets you practice without wasting OC or contaminating your house. Fill a coffee can with water, set it on a table outside at 10 and 20 feet, and practice hitting the target. You’ll learn how the stream travels, how much trigger pressure you need, and where to aim. That five minutes of practice could make all the difference.
The cartridges are color-coded for safety — red is live OC, blue is water. Both deliver the same 7 bursts at the same 20-foot range, so your practice session mirrors exactly how the live round will perform. Loading and unloading is the same simple slide-in process.

Practical Details
One OC pepper cartridge (red) and one water practice cartridge (blue). 0.99 oz each. 7 one-second bursts per cartridge at 20-foot range. Compatible with all Mace Pepper Gun models including the 2.0. Mace provides a 1-year warranty on canister and nozzle. The water cartridge is reusable for concept — but once empty, it’s empty. Buy extra if you want ongoing practice.
Train with water, carry with pepper — the smart way to stay ready.
Frequently Asked Questions
Can I refill the water cartridge myself?
No. The cartridges are pressurized and sealed at the factory. Once empty, you’ll need to purchase a new one. They’re not designed for user refilling.
Does the water cartridge spray the same way as the OC?
Yes. Same pressure, same stream pattern, same range. That’s the whole point — your practice session feels exactly like the real thing so there are no surprises when you switch to the live round.
Should I get this or the dual OC pack?
If you’ve already practiced enough and just want live rounds, get the dual OC pack. If you want to keep practicing or you’re setting up a Pepper Gun for someone new, the OC/Water pack gives you the training option plus a fresh live cartridge.
