Practice Matters — This Pack Makes It Easy
Most people who carry a self-defense tool have never actually used it in a stressful situation. That’s fine — that’s the goal. But it also means that when a real situation happens, the first time you’re running through the mechanics under any kind of stress is the moment that counts. The water practice cartridge in this pack removes that variable. You can fire the Pepper Gun 2.0 repeatedly, learn exactly how the trigger feels, where it aims, and how the grip sits in your hand — all without deploying OC formula. Then you load the live cartridge and carry with confidence.
The live OC cartridge included performs identically to the one shipped with the Pepper Gun 2.0 — 0.99 oz, 7 one-second bursts, 20-foot range. This pack just adds the training component alongside it.
Who This Dual Pack Is For
This pack makes sense for two groups of people. First, anyone who is new to the Pepper Gun 2.0 — whether they bought it used, received it as a gift, or simply never used the practice cartridge that came with the original unit. Running through the water cartridge gives you the same orientation the original included practice cartridge was designed to provide.
Second, this is a good pick for anyone who wants to refresh their training periodically. If it’s been more than a year since you handled the Pepper Gun 2.0 under any kind of simulated pressure, a water cartridge session is a reasonable maintenance habit — especially if you’re also replacing an aging live cartridge at the same time.
Instructors who run recurring training sessions with the same students also find this format useful for periodic refresher drills without consuming live OC inventory.
Is This the Right Choice for You?
Choose the OC/Water dual pack if you want:
- One live OC cartridge and one practice cartridge together
- The ability to safely train with the Pepper Gun 2.0 mechanics before carrying live
- A periodic refresh for someone who hasn’t handled the unit recently
- An introductory pack for a new Pepper Gun 2.0 owner who didn’t use the original practice cartridge
Consider something else if you need:
- Maximum OC capacity — the dual OC pack gives you two live cartridges instead of one
- The gun itself — this is a refill/practice pack only, not a complete unit
How It Works
Both cartridges in this pack are drop-in compatible with the Mace Pepper Gun 2.0. The water practice cartridge is identical in size and weight to the live OC cartridge — it loads the same way, fires through the same mechanism, and gives you the same trigger feel. The only difference is that it contains water instead of OC formula. That means your practice session accurately replicates the live-fire experience without any risk of accidental exposure.
Use the water cartridge first. Run through the draw, grip, aim, and fire sequence multiple times until the mechanics feel natural. Then load the live OC cartridge and carry. This sequence is the same one the Pepper Gun 2.0 is designed around — the practice cartridge included with the original gun exists for exactly this reason.
Each OC cartridge delivers 7 one-second bursts of OC pepper formula in a stream pattern at up to 20 feet, from any angle. Store the spare water cartridge separately so there’s no confusion about which is loaded.

Frequently Asked Questions
Is the water cartridge reusable after the water runs out?
No. The water practice cartridge is a single-use item. Once the 7 one-second bursts are expended, the cartridge is spent and should be discarded. It’s not designed to be refilled. If you want additional practice sessions beyond what this pack provides, the OC/Water dual pack can be purchased again, or you can look for water cartridges sold individually if available in your market.
How do I keep the water and OC cartridges from getting mixed up?
The cartridges in this pack are color-coded — the OC cartridge is red and the water cartridge is blue. That makes it straightforward to identify which is which at a glance. When you load the live OC cartridge into the gun, store the water cartridge separately and clearly labeled so there’s no confusion if someone else handles the unit. A simple label on the cartridge or storage bag does the job.
How many times should I practice with the water cartridge before switching to live?
There’s no fixed number — the goal is to reach a point where the draw, grip, and trigger pull feel automatic. For most people, 3–5 complete firing sequences is enough to build basic familiarity. If you’re new to the Pepper Gun 2.0 format entirely, spend more time on grip and natural point-of-aim. The practice cartridge gives you 7 one-second bursts, which is the same as the live cartridge — use them deliberately rather than all at once.
Can I use this pack with the original Mace Pepper Gun, not the 2.0?
These cartridges are designed for the Mace Pepper Gun 2.0. The original Mace Pepper Gun used a different cartridge format. If you’re unsure which version you have, check the model designation printed on your unit. Using a cartridge from a different generation than your gun is designed for may result in improper fit or failure to fire. Contact Mace or the retailer with your unit’s specific model information before purchasing if you’re not certain.
