Krazy k38:
The 442, like its brother the 642 is ideal for carry because of its size and weight. I carry mine, as stated, with a Hip-Grip in my right front pocket; it just disappears and the weight is not noticeable. It works well for ankle carry as well; heavier guns seem like an anchor when placed there.
The only downside is vicious recoil when +P loads are used. I carry Speer .38 special +P 135 gr. Gold Dot hollow points in mine. It's actually painful to shoot with these rounds, and I'm not especially recoil-shy. The same load shoots much more comfortably in my 640 or 649, both of which are heavier.
My wife also carries a 442 in her purse, where she appreciates the lighter weight. She also likes the black gun because it would be harder to spot by a casual glance into her purse. However, +P loads are way too brutal for her to manage effectively. Although some may disagree with my choice here, I load hers with standard pressure full wadcutters. Not much velocity, but the sharp-edged bullets will cut holes in an assailant rather than just push tissue aside. She can also get off fast repeat shots easily. Considering that the mere display of a gun more often than not decides the issue, I consider her well-protected.
If you subscribe to the belief that a more visible gun is a better deterrent at night, then the 642 might be a better choice, having a much lighter finish. The coating on this gun tends to wear off, exposing the aluminum alloy frame. To my mind, this doesn't matter much. Same with the 442's blackened finish wearing over time. These are working guns, not safe queens, so finish wear is of little consequence.
Both the 442 and the 642 have pretty stiff trigger pulls. I had my 442 worked over by a gunsmith who specializes in Smiths, and he got it down to a decent, smooth pull with full reliability.
Hope this helps.
