I'd have to go with the Uncle Mikes as well. It is slightly less bulky than the Nemesis, but at the price of each, you can buy both to try out. I also like the PocketRoo from Tuff Products. It carries my 442 plus a speed strip and is more ideal for large front pockets, cargo pockets and jacket pocket carry.
For kydex, take a look at Aholster.com, I have one and it works pretty well. But it is hard, no soft exterior when bending and due to size/shape it is definitely a front pocket only holster. Overall I prefer the UM.
