I use an Uncle Mike's sidekick size 0 (actually an IWB, but works well in the pocket), and it works well in the pocket of suit pants and other dress pants. It also works well in suit coat and sport coat pockets. I would like to try a leather Galco, but can't find them in the local gun shop. I'm like to try before I buy (enough boxes of holsters already), so am not real fond of ordering something I'll get stuck with.
I have trimmed the Sidekick a little to match my grip. I have a hammerless Airweight, and I have found that if I put my thumb where the hammer would be, my trigger finger in along side the trigger and guard (not in the guard), and my other three fingers around the grip (I use the wood grip, because I found the Houge and Crimson Trace snagged on my pocket), it comes out easy and very little other hand movement before shooting.
