The ruger six series are awesome revolvers. You pick one up and it screams quality, craftmanship, and durability. I own a 4 inch S.S. Security Six, which also happens to be my first handgun. Trigger was somewhat rough when I got it, but now that I've put 600+ rounds down the tube, it is quite nice. You will find that most of the rugers in the six series have a heavy/rough double action pull, but a very nice single action pull from the factory. The SP101 is a fine revolver, but smaller than the six series guns.
