Let me explain a couple of points to sort of set the scene in regards to handguns in the 'Fifties, at least in regard to my neck of the woods, especially in regard to availability of certain models of handguns.
First of all, there were no gunshops as we know them today. Guns were bought from sporting goods stores, hardware stores, and pawn shops. Pawn shop guns were not always out-of-pawn guns, but brand new. And even the best of the sporting goods outfitter catered more to the duck hunter, bird hunter, or big game hunter, hence fine shotguns or rifles were the order of the day, with maybe four to six handguns being in the showcase. It was to be many years before I saw a S&W .357 Magnum, Ruger revolvers were still in the future, and Colts were seen only on advertising brochures, except the plain Jane models.
As a kid, most of my guns were top-breaks bought from second hand shops and junk shops. My first real Colt was mail order, second hand.
So, even though certain models were available, they were not commonly seen.
