I cut my teeth on DA revolvers, but was never much good with a snubby, hence I waited 25 years before I bought one to carry. When I did, it was the 642, I prefer the hammerless design for concealed carry. I did one of my better trigger jobs on it, and got the DA pull down to a very smooth 9 pounds. I'm no sharpshooter with it, like I am with my other DA revolvers

but I can hit your hat out to about 20 paces, as far as I'm ever likely to shoot it. Clay pigeons on a dirt bank at 7-10 yards are in serious peril with every shot.
As mentioned, the tiny little sights are horrid, and it doesn't help that they're matte finished, they're hard to see in good light, let alone in the dark. I've learned to point shoot with the little blaster, and despite the horribly slow reloads, I carry it pretty often. I'm not big enough to make pocket carry work for me, so I use a metal clip (available from Midway for the ridiculous price of $20, but it works) attached to the starboard side for appendix carry, and it simply disappears under a t-shirt, given enough gut to disguise it. Most of us geezers don't have that issue, the "flatbellies" (as my Dad use to call them) might need to get a little more creative, or carry at 4 o'clock, meaning behind the right hip for northpaws. The clip alleviates the need for a holster, and if there's a downside, it's that the clip goes BOING when you fire it. It's a little irritating, but you can get used to it.
Painting the sights with brightly colored fingernail polish helps immensely when there's enough light, and if you don't like your color choices, a little acetone will let you remove it and try again with different colors. You might get some funny looks when you buy fingernail polish in billious colors, but you can either say it's for your girlfriend, or just wink and sashay out the door, your choice.
My 642 originally came with a Crimson Trace grip, which is a wonderful tool for low-light applications, especially when you put the dot on the bad guy's nose.......NOBODY wants to get shot in the face, and that garbage about putting it in the middle of his chest is hooey, he probably won't see it. Put it on his nose and he'll go into duck-and cover mode INSTANTLY. Unfortunately, most of the Crimson Trace grips are on the large side, and don't help the carryability aspect. But they sure make point shooting a lot easier!
If I only had one J-frame, it would be the 642. It was my first, but not my last!
