The black 22/45 Lite has been dropped and now only the Cobalt and then new blue anodized model are listed. At first I thought that that was a shame. I think the black version looks a lot better than either the swiss cheese Cobalt, or the new blue anodized Lite. But then I realized that both of the available versions have the actual barrel open to air, so now I am wondering if there have been some sort of overheating issues with the older non ventilated versions of this gun? My original Gold LIte has performed flawlessly, has anyone else seen problems that may have been heat related?
