I have the 640-1, 642, 638 and several / many other J frames. I love the 640-1 for ankle carry as a BUG. I can and do pocket carry it but prefer the lighter 642 or 638 for that as then don't even notice they are there. But I have and do carry the 357 magnum in my pocket occasionally. I like to shoot the little bugger at the range. The crack of a 357 magnum from a diminutive J frame always wakes up a few people in the vicinity. I will also say that with 38 +P ammo the heavier gun is easier to do follow up shots.
The cousin 649-3 is also a 357 magnum "humpback with a shrouded hammer but open for cocking ability. The difference between the 640-1 and 649-3 is only the shroud and I like both equally. The 640 is a little less "humpy" for concealment but it's a very minute difference.
