Superpelly: What a great find. I had a Model 28 6-inch barrel for years, and even though it was a little too big for comfortable carry, it was my most often fired pistol. If I missed a shot with the 28, I knew it was my own fault, NOT the pistol. And in my area they are just about impossible to find without having to mortgage the house.
Your 4-inch will do wonders for you, and I wish you well with it, It's definitely a keeper, wish I still had mine. Enjoy the ride.

sometimes your shadow follows,
BUT when your shadow says "Cuidado!!"
