I looked into paddle holsters a while back for concealed carry. Unless U buy the very expensive ones (I think Kraemer makes a good one for over $100), they supposedly do not carry concealed very well. U are better off with a nice leather belt holster - like a Galco Fletch or Galco Concealable.
I wouldn't worry too much about lasers yet. Besides, unless U get the guiderod laser setup, any light or laser U attach to your gun will keep it from fitting into your holster. I suppose U could get a tac light for when it becomes your nightstand gun, but you'll have to remove it for carry use.
