Actually, that's a 642. 442 is a blued steel/black aluminum gun. That's stainless steel and white aluminum.
The 642 is better for a pocket carry. Sweat doesn't hurt the stainless.
I like mine so much, I bought one for my daughter. I use a pocket holster, but if you want a waist holster, I suggest a Fobus. This is kydex, and it grabs the gun at the trigger guard. I have a couple of leather holsters made for Smith J frame guns, but without a hammer, it is kind of difficult to keep it in the holster. Safety strap ain't got nothing to hold on to.
