Excellent choice! My go-to carry rig is a 642 in a SideGuard leather IWB holster. I've fallen asleep on the couch wearing it, because it's so comfortable. It probably saved me from a very nasty bruise once when one of the donkeys kicked at me, and made square contact with that revolver instead of my hip bone. It's got so much wear on it from being carried, it looks like it's 20 years older than it is, but still shoots great.
