As already mentioned, they were only offered for a 4-5 period. Low volumes and didn't have much of a following unit recently. They now sell for four figure prices regularly on the auction sites. Rumor has it they were made in .357 mag as well as .45 Colt; but I have never seen one chambered in anything other than .45 Colt. To be blunt and honest they are probably one of the worst quality revolvers Colt ever made. The transfer bar firing system had an inherent design flaw where if the hammer was lowered from half cock without first releasing the trigger before the hammer is fully lowered the action will lock solid with the bolt down on the cylinder between the locking notches. Colt has long been known for their superior metallurgy, the frame on the Cowboy was die cast (non-forged). Red loctite was also used by the factory on the screws holding the revolver together. The Cowboy represented a lot of production "firsts" for Colt, and thankfully lasts that died with the model.
