I carry concealed (never IWB) with the same holster(s) that I use for OC.
The box of holsters is only indicative of the selection of guns available for defensive purposes. I normally utilize a Serpa CQC, although I don't consider preventing a snatch that big of a problem and 90% of the time my primary is a 1911. Consistancy of equipment is important to me.
The desire to have fashion options i.e. color and texture plays a part too.
