What is an IWB or OWB?

This is a common question.  Real simply put, IWB is Inside the Waistband and OWB is, you got it, Outside the Waistband.  Both can be used for conceal carry, but generally the IWB wins out in that department.  When you wear the IWB, the only thing that is visible is the handle of the firearms and the belt loops.  A relaxed fit shirt is usually all that is needed to conceal the firearm.
