Designed in a vertical orientation and configured for right-hand draw, this holster is sized for 3" to 4" barrel revolvers and features a durable black Cordura® harness for lightweight strength and all-day wearability. With Shoulder Size 02 sizing for a supportive, stable fit, the Uncle Mike’s Sidekick 83021 (UPC 043699830213) is an excellent choice for revolver owners who want a practical alternative to belt carry—especially for driving, outerwear seasons, and long hours outdoors.
Vertical Shoulder Carry: A Smarter Way to Carry a Revolver for Long Periods
Shoulder holsters are popular for good reason: they distribute weight across the shoulders rather than concentrating it on the belt line. For many revolver owners—especially those carrying medium-to-large DA wheelguns—this can mean significantly better comfort during extended wear. The vertical holster orientation keeps the revolver positioned up-and-down, helping it ride naturally under jackets while remaining accessible.
Why vertical shoulder holsters are a great option:
Comfortable carry during long seated periods (driving, riding, commuting)
Better weight distribution for heavier revolvers
Practical access under coats, jackets, and outerwear
Helpful when belt carry conflicts with backpacks, chest straps, or heavy clothing
Stable positioning that keeps the firearm closer to the body
If you spend time in vehicles, hunt in colder weather, or simply prefer weight off your belt, a vertical shoulder rig can be a game-changer.
Designed for Medium/Large Double-Action Revolvers (3"–4" Barrels)
This Sidekick model is designed to fit medium and large double-action revolvers with 3" to 4" barrels, making it a strong match for many popular defensive and field revolvers in that size range. Proper sizing matters—especially for revolvers—because it affects retention, comfort, and draw consistency.
Benefits of correct revolver fitment:
Improved stability with less shifting during movement
Cleaner, more predictable draw stroke
Reduced printing compared to ill-fitting universal holsters
Better balance and comfort under outerwear
If your DA revolver falls within the 3–4" barrel range, this holster is built to carry it in a way that feels secure and natural.
Shoulder Size 02: Built for a Stable Harness Fit
Harness sizing is critical for shoulder holsters because it determines how well the rig stays in place. The Shoulder Size 02 configuration is designed to deliver a supportive fit for the intended wearer size range, helping keep the holster stable and the firearm positioned consistently.
Why harness sizing matters:
Helps maintain a consistent draw position
Reduces bouncing or shifting when walking
Improves comfort by distributing weight evenly
Helps prevent strap slip and hot spots during all-day wear
A properly fitted shoulder rig feels integrated—so you can focus on your day instead of constantly adjusting gear.
Black Cordura Harness: Durable, Lightweight, and Ready for Real Use
The Sidekick system uses a black Cordura® harness, a widely trusted material known for durability, abrasion resistance, and practical comfort. Cordura is common in outdoor and duty-style gear because it holds up well to daily handling, travel, and varied weather conditions while keeping weight manageable.
Why Cordura is ideal for shoulder rigs:
Durable construction for regular use
Lightweight feel that reduces fatigue over long wear
Abrasion resistance for travel and outdoor conditions
Easy care and maintenance compared to delicate materials
The black finish also keeps the rig discreet under outerwear and blends with most clothing choices.
Right-Hand Draw: Familiar Access and Consistent Handling
Configured for right-hand draw, this holster supports a familiar access pattern for right-handed shooters. Consistent draw orientation is particularly important for shoulder carry, where you want your firearm positioned predictably under a jacket or vest.
Right-hand design advantages:
Natural draw motion for right-handed users
Consistent access under coats and jackets
Better positioning compared to ambidextrous “one-size” solutions
If you plan to carry regularly with a shoulder rig, a dedicated right-hand setup supports comfort and confidence.
Perfect for Driving, Outerwear Seasons, and Field Carry
This holster is especially useful in scenarios where belt carry can be uncomfortable or hard to access:
Driving and long commutes, where waistband carry can dig in
Cold-weather carry under coats, flannels, and jackets
Hunting and outdoor work, where packs and belts can interfere
Ranch/property use, where comfort and accessibility matter
Anyone who wants a practical alternative to hip holsters for heavier revolvers
A shoulder rig can keep your revolver accessible in positions where belt carry becomes awkward—especially when seated.
