I am really glad you posted this. I have some history with the Colt Detective Special, which which the new (2017 on) Cobra sounds to be a stainless steel copy. Not sure about an alloy framed revolver, but I'm a big fan of the steel framed version.
After a lot of trial and error, I settled on a steel framed Colt 1911 Commander in .45 ACP as my primary range and self defense firearm. Did a lot of range work with it. One day my range instructor broke out his Detective Special back up piece and "forced" us to put in some practice with it. I say forced as I had no interest in shooting a puny, short barreled .38 Special.
That little .38 felt like an extention of my hand. With no effort, the bullets went exactly where I willed them. I was astonished at the accuracy and ease of shooting with that little, short sight- axis revolver.
I wanted one, but unfortunately they had somewhat become collectors pieces (as I suspect the original Cobras are). Eighteen years later an acquaintance was trimming down his collection and sold me his. I am very much looking forward to some range time with it.
