Lavan,
I own two of the mod 625's the 5 inch and a 3 inch both .45 ACP. They are without a question one of the more accurate stock revolvers available.
On double action the pull is smooth, on single it is a crisp release. The recoil is flattened due to the weight of the weapon which allows for a fast follow up shot. Due to the six rounds all ready in a full moon clip, speed loading is really fast for a revolver. On the down side the weight and bulk of the weapon should be considered before obtaining one for CCW.
I also have one of the 455 2.5 inch barrel Taurus Trackers in .45 ACP. I'm not happy with it at all, but I have heard good things about the 4 inch barrel model with adj sights, ported barrel.(the Taurus are now at a premium as not too many chumps.......I mean people have bought them.)
Plan on spending about $400.00+ on the S&W, you should be able to get the Taurus for $350.00 or less.
good luck
