I've found in the two odd years I've been carrying that a horizontal shoulder rig solves certain dilemmas IWB carry cant fix , insofar as my particular body type goes. Think 30" waistline, which naturally deprives me of the option to carry spare magazines. Even a single stack mag looks like a copy of the Holy Bible under my shirt. My Miami Classic holster permits me the ability to carry two spares and the weapon without being stopped by a retail loss prevention employee, and I've practiced my draw enough to get the gun out efficiently under stress. Having access to an outdoor , isolated range helps with this part of things. All that being said, who else here employs this carry method ?
