Reload and Train With One Purchase
From what I’ve seen, the people who do best in a real situation are the ones who’ve practiced. This dual pack gives you both — a live OC cartridge to keep your Mace Pepper Gun 2.0 loaded for defense, and a water cartridge to practice your aim, trigger pull, and deployment without wasting your live round.
Who This Refill Pack Is For
This is the right choice if you’ve used your original cartridges and want to replace both at once. It’s also ideal for someone who believes in regular practice — run the water cartridge in your backyard to stay sharp, then load the OC cartridge and know you’re ready.
If you’re buying a Pepper Gun 2.0 for someone as a gift, including this refill pack means they’ll have a spare of each cartridge type from day one.
Is This the Right Choice for You?
Choose this OC/Water Dual Pack if you want:
- One live OC cartridge plus one water training cartridge in a single purchase
- The ability to practice regularly without using your live round
- A complete reload that mirrors what comes with the Pepper Gun 2.0 originally
Consider something else if you need:
- Two live OC cartridges — get the OC Dual Pack refill instead
- Cartridges for a non-Mace pepper gun — these fit the Mace Pepper Gun 2.0 only
Why Practicing Matters
Under stress, you fall to your level of training. That’s not just a saying — it’s what happens. The water practice cartridge is weighted and pressurized to match the live OC cartridge, so when you practice, you’re building real muscle memory. The spray pattern, trigger pull, and range are all the same. The only difference is water instead of pepper.
The live OC cartridge contains 0.99 oz of pepper formula with 7 one-second bursts reaching 20 feet. Once you’ve practiced with the water cartridge and you’re comfortable with the Pepper Gun’s operation, load the OC cartridge and carry with confidence. You’ll know exactly how the gun handles, where the spray goes, and how the safety works — all before it counts for real.

Practical Details
Includes one OC pepper cartridge (red) and one water practice cartridge (blue). Each contains 0.99 oz and delivers 7 one-second bursts at 20-foot range. Total weight 0.35 lbs. Each cartridge measures approximately 4 x 1.25 inches. Compatible exclusively with the Mace Pepper Gun 2.0. Covered by a 1-year warranty on canister and nozzle.
Practice with the water cartridge, load the OC cartridge, and carry knowing you’ve done the work to be ready. That’s what real preparation looks like.
How do I tell the OC cartridge from the water cartridge?
They’re color-coded. The OC pepper cartridge is red and the water practice cartridge is blue. This makes it impossible to mix them up during loading. Always double-check the color before loading for defense versus practice.
Can I practice with the water cartridge indoors?
Technically you could, but it’s better to practice outdoors where you can safely aim at a full 20-foot distance. The water cartridge fires with the same pressure and range as the live cartridge, so you want the space to see the full spray pattern and practice at realistic distances.
Is the water cartridge reusable?
No. Like the OC cartridge, the water practice cartridge is a single-use pressurized cartridge. Once you’ve used all 7 bursts, it’s spent. But it’s served its purpose — you’ve now practiced with the exact feel and function of your pepper gun before you need it for real.
