I've used this for years in various pistols. Although today I had the most impressive experience. I recently purchased a KJW CZ75 which didn't work very well with the gasses I had as it works best with the Co2 magazines. However, with this gas I managed to dump 3 and a half magazines rapidly before the power dropped. I cannot get this good of a result on any of my other pistols or gasses. Excellent gas, it's actually quite a powerful gas even though it's often called 'green gas' it doesn't choke your gun with lubricants and it's also very consistent in anything but cold weather. Worth the money!
