The Uncle Mike’s Pro-Pak (brand part number 77150) is an ambidextrous horizontal shoulder holster built from an extra-thin laminate for concealability, sized for large-frame autos with 3.75-inch to 4.5-inch barrels. Waterproof closed-cell foam padding lines the harness for comfort and to keep moisture off the pistol, while a smooth nylon interior protects the finish and helps both the draw and re-holster. The lightweight harness yokes use hook-and-loop adjustment for a quick, no-tools fit, with non-abrasive material against the body and a smooth exterior that will not snag clothing.
