I handled some more guns today including a colt king cobra and model 19 carry comp. I can see how the extractor rod could get stuck in the cylinder on the colt. And I believe the extra weight of the k-frame would be a benefit when shooting over the lighter kimber (although I’ll probably end up with a 2” kimber at some point). So it looks like Smith K frame for the win. Now to find one at a reasonable price!
