I am interested in trying out a shoulder rig with my CZ-75. Does anyone have any recommendations? This one looks pretty good to me, but I'd like a bit of input before I lay down a hefty chunk of change. http://www.rossleather.com/Shoulder...Shoulder_Rig_With_Mag_Pouch/product_info.html Also what are the advantages and disadvantages of using a horizontal vs. vertical holster? Seems to me like horizontal would be a more natural draw.
