I agree with bermo61 that you should try to handle and shoot both if you can. See which one feels better in your hand. I've got a 686, 620, and 66 all in 4 inch. Love them all, really do. However, I prefer the half-lug design. They just feel much better in the hand to me. As I shoot mostly .357s (often 125 grainers) I tend not to use the 66 much. Croyance is right, the 620 doesn't feel like the K-frame....but it's close. Holding them both, you can tell that the 620 is the bigger gun, but it isn't a huge, huge difference. Also, as has already been stated, the half-lug guns will have more "flip" with comparable loads than the 686. That's why it'd be good if you could shoot them both, to see if it makes enough difference to put you off of the 620. For me, it didn't. And, if you shoot mostly .38s then you won't really have a problem at all. Let us know what you end up with and give us your take on it.
