KT would be the variation that the Model 19/66 would be built on. K size, adjustable sight cuts.
The 686 is more robust and makes a better target and range gun. The 19/66 are smaller, less robust, but make better trail and camping guns, in my opinion
Walkalong said:I have a 6" 586. Nice, but a bit barrel heavy. I believe I would prefer a 6" 66. I am looking at the 66 and 686 with a 4" barrel
Although I prefer the 6" , I do think the 4" is almost perfectly balanced. Either way though, I do prefer the full underlug barrel on my 686s compared to the k-frame.
