Paddle holsters seem ok for a trip to the store, but wearing them all day getting sweaty, etc. just never worked for me. I've seen people try to use them at the range and I've seen them draw the whole shee-bang out of their pants.
I have a video of a Fobus paddle holster being broken in half with little effort in a gun-grab scenario. I'm on the road right now, but I have it at home - I can e-mail it to you if you want to see it, I'd rather not post it on an open forum. But just don't get a fobus.
Spend the extra $20 and bump your holster budget up to the $50-60 range. You'll thank yourself later.
Have you tried IWB? concealed = concealed you know
I have had great luck with blade-tech... yeah yeah, I'm bucking the leather crowd and going with Kydex. I have a couple Galco IWBs and they have been great as well, Galco is probably your best bet for the .380.
What model of Smith is it?
