I currently have been looking to buy a full size .357 revolver with a 4" barrel. Note: this gun will be used only for target shooting (not carry). So far, I've narrowed the search down to three options... a Taurus Model 66, a S&W Model 686P, or a Ruger GP100. Right now I'm leaning towards the S&W because of all the good things I've heard about them, but they are a little pricey compared to the other two.
I would greatly appreciate your experiences or opinions of these three guns.
