The K6S is an acquired taste. There are plenty of less flattering reviews but most of them come down to some variation of it’s not like my other traditional S&Ws and or it’s someone who hasn’t carried it a few months and shot it enough to appreciate its finer qualities.
I started with the 2 1/2” SA/DA version and liked it a lot. When I came across a like new in box 3” DAO model at a great price I snapped it up asI really prefer a 3” barrel in .357 Mag for ballistic efficiency.
I’m normally not a DAO fan but the trigger on the K6S is exceptionally smooth and for longer shots, stages extremely well.
Size wise its closest comparison is to the SP101, a little heavier than the J frame but not significantly larger.
I have gel tested some very effective .38 +P rounds but prefer .357 Magnum self defense loads. Off the shelf Remington green and yellow box HTP hollow points in both .38 +p and ..
357 Mag gel test extremely well. At first glance the bullets look the same but on closer inspection are different and each is obviously designed for the appropriate velocity window.
For 357 loads the steel frame models are the way to go as the extra weight, in conjunction with a good energy absorbing rubber grip tame the recoil and make it very shootable.
If I owned a light weight model it would be .38/.38 +P only and I’m not particularly recoil sensitive. It’s largely a matter of muzzle rise and follow up times.

Back to the trigger, the only revovler I have with a clearly better trigger is my custom shop S&W 625 race gun, which has a trigger that is both very light and very smooth.

All that said, in terms of concealed carry revolvers my Taurus Executive grade 856 has a trigger that matches the Kimber in weight and smoothness and is equally well suited to concealed carry. It’s major draw back is the standard grips do not allow for clear ejection of the cases nor do they work with some speed loaders.
To make it worse the after market grip options are limited and I had to do some carving on the speed loader “style”relief on the left stock on the replacement set to actually make it cleanly eject and allow unobstructed speed loader reloads.
It’s .38/.38+P only but it’s also selling real world for down around $500, substantially less expensive than the K6S and just as enjoyable and functional.
