In 1977, when I was young & dumb, I bought a blue steel 6" Security Six.
I had just turned 21, and this was my first new handgun purchase. It has been shot a lot. Mostly a diet of .38 SPL, but many boxes of .357 mag.
I still have it. Thousands of rounds, and thousands of dry firings later, it is still in good shape.
I have mellowed a bit with age, still, I am extremely impressed by the good service that Ruger has given me.
I love my S&W 27-2. I love my S7W 13-2. I have owned a variety of .357s over the years. I added a 4" SS Security Six to the collection, and it has given the same good service.
If I could only own 1 .357 revolver, it would be a Security Six.
