I have carried the following "kit" guns:
S&W 317
S&W 63
Ruger SP101 4 inch .22
S&W 617 4 inch
NAA Black Widow in 22 mag.
My current favorite is a Beretta Bobcat loaded with CCI Mini Mags. It is surprisingly accurate and easier to shoot than the 317 out to 10-15 yards.
The older (more experienced?) I get the more the idea of a Kit gun has evolved. Part of this is due to the stray dogs, coyotes, and hogs in the area. A lightweight 3-4 inch double action in 357 loaded with 38+P ammo is on my next list
