Mace Pepper Gun 2.0 Dual Pack OC and Water Refill Cartridges – One Live OC Cartridge, One Water Practice Cartridge, 20-Foot Range, 7 Bursts Each

Practice With the Real Thing — Then Load the Real Thing

A defensive tool you’ve never practiced with is a tool you might fumble when it matters. The Mace Pepper Gun 2.0’s refillable design exists partly because practice should be part of ownership — and this dual pack supports exactly that. One water cartridge to train with, one OC cartridge to load when training is done.

The water cartridge is functionally identical to the OC round in size, weight, and operation. Trigger pull, grip, aim — everything translates directly. When you’re satisfied with your accuracy and draw speed, swap in the live round.

Who This OC/Water Dual Pack Is For

This pack is the right choice for Mace Pepper Gun 2.0 owners who’ve gone through their original water practice cartridge and want to restore the training option without buying two separate OC packs. If you received the gun as a gift with only one cartridge, or bought a refill pack previously that didn’t include a water round, this brings the setup back to factory spec.

It’s also worth considering if you’re new to the Pepper Gun 2.0 and want additional practice time before loading the OC round. The water cartridge costs nothing to fire — there’s no reason to skip it.

If you’ve already worked through training and just need live OC cartridges, the OC-only dual pack (sold separately) provides two live rounds instead of one.

How the Water Cartridge Works — and Why It’s Not a Shortcut

The water practice cartridge isn’t a toy or a placeholder. It’s the same form factor as the OC round — same length, same weight, same trigger resistance. When it fires, it sprays water in the same stream pattern at the same range. You’ll see exactly where your shot lands, which lets you correct grip, stance, and aim before you ever use the live round.

Training this way builds the kind of reflexive confidence that a quick review of instructions in an emergency does not. The 7-burst capacity per water cartridge gives you enough repetitions to work through the mechanics and develop consistency before switching to the OC round for carry.

Practical Details

Each cartridge measures 4″ x 1¼”. The dual pack weighs 0.35 lbs total. The OC cartridge is red; the water cartridge is blue — easy to tell apart at a glance. Both contain 0.99 oz of their respective fill and deliver 7 one-second bursts at up to 20 feet. Compatible with the Mace Pepper Gun 2.0 only. Mace covers both cartridges with a 1-year warranty on canister and nozzle.

Own the Mace Pepper Gun 2.0, use the practice cartridge, then carry the live one — that’s the full system working as intended.
