If I can add my two cents on this, I'd been debating whether to get the dan Wesson co2 revolver for ages since it's the most realistic revolver yet, and let's face it this is all about playing cops and robbers is it not?
The only thing that bugged me for a while was this issue of them being too hot and like someone said too cold with the power down shells for using in the field BUT...
There's a handy video on youtube that explains that with the insertion of a screw and nut, you can adjust the power of the gun to boost to exactly where you want it using the power down shells. It seems simple enough and looks like it was intended that way in the design in the first place so I know I'll be getting a dan Wesson over anything else, you get what you pay for right? If you want a gun that lasts five minutes get the cheapo, if you actually want to use it regularly...surely the dan wesson is the way to go?
