Range Rat: My daily carry rig is a 442 with CT grips in a carbon-fiber Blackhawk Serpa paddle holster. The Serpa is a great holster--lightweight, easy to carry and conceal, with a positive retention system to ensure the gun doesn't slip out accidentally. I don't have any shots of the holster with the 442, but here it is with a 342 wearing the same CT 405 lasergrips:
The Serpa comes with both a belt slide attachment and a paddle. I much prefer the paddle for the convenience of being able to put it on and take it off quickly.
