The Cobra is a combination of an IWB and pancake holster. It works best as an IWB, in my opinion, but works better than many standard belt holsters when worn as a pancake. It is quite versatile, and when you are able to conceal a strong-side belt holster, the draw is less complicated and the holster more comfortable.
When it is necessary to go to an IWB type, the Cobra has the good attributes of the Wright Banshee, but with the added component of a belt loops on extended wings to allow carry on the belt outside of the trousers. The IWB loops are adjustable for cant and ride. This may be the only holster you will need.
