For many years I used a Bianchi Model 100 IWB holster and still do occasionally, depending on what I'm carrying and how I'm dressed. For several years now I've been using the Crossbreed "Super Tuck" which I have a number of for different pistols. I also am particularly partial to Mernickle holsters, both belt and IWB. Also use some of the High Noon IWB holsters, some of which are "tuckable" too. Of all of them I find the Crossbreed holsfers offer the fastest presentation, but which holster I wear depends entirely on how I'm dressed and what I happen to be carrying. It's easy to become a "holster junkie", but every one I have serves a purpose, "absolute invisibility' and quick presentation being my primary concerns.
