I have owned four revolvers in my lifetime; all of a different caliber, and all Rugers. The first was a SP101 in 9mm, the second was a Vaquero in .44mag, number three was another SP101 in the new .327 federal mag, and my current revolver is one I have been wanting for a very long time - a GP100 3" barrel with the factory grips in .357mag. I have been foolish in that I traded one for another in an effort to find the right one. In hindsight they all were the right one and I wish I had them all back. So, in reference to the original post...I prefer the GP100 in .357mag. Putting it in my hand is like putting on my favorite old pair of slippers, it's a very comfortable fit.
