See other products by Umarex


Specially made and tested with close attention to tight tolerances and with clean C02, the Umarex 12-gram CO2 cartridges have uniform neck dimensions. That makes it more likely that every cartridge will pierce properly and gas will be evenly dispersed into your air gun. These are standard cartridges that work well with most 11-gram CO2-powered airguns, but are especially suited to Umarex's airguns.

  • 12-gram C02 cartridges
  • 40 count
  • High-grade C02

Things I liked:

I've only used about 5 of them so far, and they work as advertised. I selected the Umarex brand only because the S&W 586 Umarex brand .177 cal. pistol instructions said to use only them. Hey, the cost difference between the other brand and Umarex was next to nothing, and I'm not in the habit of purchasing a new anything and then doing something that might void the warranty right off the bat. Give me a few months and a few hundred CO2 cartridges behind me, and I'm sure I'll be purchasing whatever ones are the cheapest... For now, they worked fine.

Things I would have changed:

On one of the cartridges, I only got approx. 30 pellets through the S&W 586. I can imagine that in whatever manufacturing process that fills these cartridges, one could get a lesser charge now and again. No big deal. As I'm new to CO2 pellet pistol use, so at first I thought I hadn't tighten up the disk in the grip enough to ensure a proper seal and maybe some leaked out? When changing the used cartridge out, it did not appear loose at all, so maybe just a cartridge that has a little less in it. The next two CO2 cartridges gave me 50 or so shots as the PyramydAir S&W 586 website states... .
