Sounds like the Freedom Munitions ammo is too weak for the recoil spring in your pistol (re-manufactured ammo is generally downloaded due to the reused brass). Since your Kahr pistol is new, the recoil spring is at peak strength and will have problems cycling some low-power ammunition. As your recoil spring weakens, the strength of your recoil spring may fall to the point where this ammo will work for you. If you want to shoot the re-manufactured ammo, you'll probably have to get a weaker recoil spring and switch it out when shooting it. Just be sure to replace the weaker recoil spring with the original full-strength one when shooting anything else. There's nothing wrong with the ammo or the pistol, the problem is that the pistol isn't tuned to fire this particular type loading of ammo.
