The Uncle Mike's Sidekick Vertical Shoulder Holster in Size 01 is a right-hand carry solution built for shooters who need their sidearm accessible and secure during active work or outdoor pursuits. Designed to fit medium and large frame semi-autos with 3–4" barrels, this black Cordura holster distributes weight evenly across your shoulders and torso, making it practical for extended wear whether you're hiking, working the range, or in the field. The vertical carry position keeps your firearm close to your side and lets you carry it inside or outside a jacket—versatility that matters when your activities change but your gear doesn't.

The Sidekick's retention system combines a self-adjusting belt loop with a retention strap secured by a combination adjustable buckle and snap, so your gun stays put even when you're moving hard. The fully adjustable shoulder harness uses 2½"-wide nylon web straps and a self-centering back-piece to keep everything balanced and comfortable. An offside tie-down anchors the holster to your belt and gives you a secondary carry point for a speedloader or magazine case—vertical or horizontal, depending on your reach and preference. The holster fits chest sizes up to 48".

If you carry a compact or mid-size semi-auto and want a shoulder rig that doesn't feel like dead weight after a few hours, the Sidekick delivers the kind of reliable, unpretentious design Uncle Mike's is known for. It's not flashy, but it works.
