I think they are a good value as a knock around, small game, plinker and would suit these purposes well. Hewever, don't even try to compare them to the K22, you will be greatly disappointed.
As a side CA's customer service is top notch in my experience. I bought a used .38 snubby that I thought the cylinder to crane fit was a little sloppier than it should have been. I called CA and they said that their lifetime warrentee follows the gun and to send it in for a look see. Not only did they replace the crane, fixing the problem, with out charge but they also picked up the shipping cost in both directions.
