I've got an Uncle Mike's pocket holster and IWB for my 642. I've also got a High Noon Hidden Ally tuckable. I use the pocket holster rarely, but it is very nice to have when you want it. I don't ever, ever use the UM IWB. The cheap plastic clip doesn't hold. I tried using it for 3 weeks anywhere from a 1 o'clock to 6 o'clock position. I couldn't tell you how many times the whole thing rode up and out of my pants. The hidden ally is a non-molded leather IWB that I have found works great. I rarely use the tuckable option, but it's nice for church and going out to eat when my pants don't work with the pocket holster.
