One of my favorite hand guns is the Ruger GP100 .357 mag.
I actually bought this one and presented to my wife as a birthday gift several years ago. She liked the design because it was simple, reliable and would shoot .38 rounds, .38 special as well as .357 magnum.
This allows her to work her way up to heavy rounds and keep the costs down at the range.
This gun is a great shooter. I love the finish and the grip is a joy to hold. Just like my wife!
