Uncle Mikes
The Uncle Mike's Sidekick Vertical Shoulder Holster in Size 03 is a practical choice for shooters who want to carry a medium or large double-action revolver with a 5–6.5" barrel across their torso. Built from tough black Cordura material, this right-hand holster distributes weight evenly across your shoulder and side, making it comfortable enough for extended wear during hunting, range days, or field work. The vertical carry position keeps your firearm accessible while remaining relatively concealed under a jacket or shirt, and the design works whether you're wearing it inside or outside your outer layer.
What sets the Sidekick apart is its balance of retention and adjustability. A self-adjusting belt loop holds the holster snug against your side, while a fully adjustable shoulder harness with 2½"-wide nylon web straps and a self-centering back-piece lets you dial in fit for your frame—the system accommodates chests up to 48". A retention strap with a combination adjustable buckle and snap keeps your revolver secure, even when you're moving hard. An offside tie-down anchor lets you add a speedloader or magazine pouch to the harness, keeping reload capability within reach.
This is solid, no-nonsense carry gear for hunters, field shooters, and anyone who spends time outdoors and wants their firearm accessible without a belt rig or waistband holster. It's the kind of holster that works quietly in the background, staying put and getting out of your way while you focus on the hunt or the shot.
