Hey, skeeter. Thanks for the reply. I live in South Florida, where any kind of heavy cover garment is out of place (except for those seven or eight days in the winter where the temp actually drops below 70...). Because of this, I was kind of leaning towards IWB carry. I can see how a solid pancake would be more comfortable, though.
For now, I'm going to be carrying my Taurus 24/7 Pro. It's a polymer framed .40, with a double-stack magazine. From what I've read, it's about the same size as a Glock 19, and it's got the picatinny rail. Companies like Milt Sparks show some high-end IWB holsters for it, and I'll eventually order one. In the meantime, though, I'm looking for ideas on what's good enough to get by on.
