I got such a nice feeling reading people recall the reasons for why a particular gun is their favorite. Just goes to show how much of a passion our hobby and interests can become...
so, on that note, I would have to say my favorite would be my blue 4" colt python. I had wanted one for so long, and a friend of the family figured he had held on to one long enough and knew that it would be given a proper home and care. He didn't exactly 'give' it to me, but for what I see them selling for now, it seems he did. Best money I ever spent.
