The day of my 21st birthday I walked into the gunstore and bought a New Model Ruger Super Blackhawk .44 Magnum. I'd spent so many years shooting my father's Ruger .44's, .45's, .357's, a .41 magnum & .30 Carbine ... as well as the Blackhawk .357 Magnum/9mm Convertible he'd previously given me ... that I decided the first revolver I bought for myself would be a .44 Magnum.
Of course, I also already owned a lightweight Commander, too.
The SA revolver is a bit of American history, and I suspect that many of us who grew up watching the TV and Drive-In Movie Westerns of the late 50's & early 60's were strongly influenced by them when it came to enjoying shooting sports. That, and my father's interest in them, were a rather strong influence on me.
The SA revolver is a viable hunting handgun.
Some folks may choose one for personal defense, or personal protection around their property, but the handling, manipulation, and unloading/loading requirements make the design a less than ideal choice when compared to more moden designs, especially when it comes to a cocked hammer over a live round. A cocked revolver (SA or DA) ... or even a cocked semiauto pistol, for that matter ... probably isn't the best choice for anyone not thoroughly trained in the safe handling of a cocked handgun, including the safe decocking of a cocked SA handgun. Lots of horror stories involving the unintentional (negligent) discharge of a cocked handgun where someone was seriously hurt or killed. There's certainly something to be said for DAO revolvers and pistols for actual defensive application.
Still lots a of enthusiasts of the venerable SA revolver, though ...
