Here's may take on the K6S as someone who first shot a revolver at age 12 (a S&W Model 36) and has loved S&W revolvers ever since. I currently own several S&W revolvers including 1 7/8" and 3" Model 36s, a 3" Model 37, 2.125" and 3" Model 60s, 1 7/8" and 4" Model 10s, 2 1/2" and 6" Model 66s, 2 1/2" and 3" Model 686+s, 2 1/2", 4" and 6" Model 19s, a 3" Model 13, a Model 14 and a Model 15, a K-22, and a Model 17, and a 4" Model 625, and a probably a couple more I don't recall off hand.
I also own a steel framed 2.5" K6S and a steel framed 3" K6S DAO. Both of them have DA triggers that are superior to any of my S&W revolvers, with the exception of the Performance Center 625.
The Kimber stainless finish does not have the polish of my various stainless S&Ws but it's still attractive and as a working gun/ concealed carry self defense handgun its more durable and superior for the role than the S&W finish.
The K6S revolvers are strong, tolerate full power .357 Magnum loads extremely well and have proven to be very durable and reliable.
The frame size is in the Ruger SP101 ballpark, in between the J and K frames, but accommodates a six shot cylinder.
The looks are an acquired taste but grow on you and the style makes IWB carry very practical and comfortable.
In short...while people love to hate on Kimber, they have built an exceptional revolver and S&W needs to start upping its game if they want to field a modern self defense concealed carry revolver.
