In 1982, I became an undercover narcotics investigator with the Licking County Sheriff’s Office in Ohio, assigned to was then called the Metropolitan Drug Enforcement Group (MEG). When I started on that unit, I carried a Walther PPK/S. It didn’t take long to realize a lightweight, six-shot Colt Agent .38 revolver paired with a shoulder holster was a better setup for undercover work.
Why I Appreciate a Good Shoulder Holster
Concealed carry laws were different then, with almost no states having a shall-issue concealed carry permit system. Most criminals in our rural county didn’t regularly carry firearms. If a drug dealer discovered a handgun during a search, or even a casual “brush-up,” it was a giveaway that you were a cop, and the deal was over.
A handgun carried on the belt, whether inside or outside the waistband, was far more likely to be discovered. A shoulder holster made more sense. A revolver tucked under the arm in a shoulder rig was much harder to detect and could still be drawn quickly if things went sideways.
Even though I’m retired now, I still carry a handgun every day. At age 68, I don’t prefer to carry a heavy pistol all day unless I’m heading somewhere with a higher risk potential. For everyday carry, I often default to my Smith & Wesson Model 638 Bodyguard .38 Special revolver.
Equipped with Hogue laser grips and weighing just 14.6 ounces unloaded, it’s a lot easier to carry throughout the day than my higher-capacity or larger-caliber handguns. Loaded with a good defensive round, like Underwood Ammo’s 158-grain .38 Special +P “Black Cherry,” I feel confident for any situation. The coated semi-wadcutter hollow-points are listed at 980 feet per second, an impressive performance.
Searching for the Right Shoulder Holster Today
Even the lightweight 638 can become noticeable on the hip after enough hours. That led me back to considering a well-designed shoulder holster. My goal was to find a shoulder rig that was as comfortable and practical as the one I used during my time on MEG.
Unfortunately, that holster is no longer manufactured. I determined some essential design parameters based on my previous experience.
- Material: The holster must be made of leather. I’ve found leather holster to be more comfortable than synthetic materials for extended wear, no matter the design.
- Draw position: It must allow me to quickly establish a solid grip. Shoulder holsters designed to carry a snub-nosed revolver muzzle down don’t have the grip forward enough for me. Due to my own shoulder problems, even my previous shoulder rig would’ve positioned the revolver too far behind the body.
- Simple harness system: My ideal design would have minimal attachment points. I did not want dual attachment points but decided I could tolerate one anchor strap if necessary.
Resuming my search with those requirements in mind, I found the Graco Masterbilt Master Agent Shoulder Rig. It immediately appeared to meet the design characteristics I was looking for and was reasonably close to the holster I wore during my drug-unit days.
Galco Masterbilt Master Agent Shoulder Rig Review
The Galco Masterbilt Master Agent Shoulder Rig is designed exclusively for revolvers from Smith & Wesson, Charter Arms and Ruger. S&W models, particularly the J-frames and K-frames, are the most compatible with the Master Agent.
Because of the revolver-specific molding, the Master Agent Rig can’t be used with pistols equipped with weapon-mounted lights. Grip-mounted laser units like Crimson Trace Laswergips work just fine because they do not protrude into the holster body.
The 638 I tested the Graco Masterbilt with has Hogue laser grips and fit the holster without issue. Hogue no longer produces laser grips, but they can still be found from retailers like Optics Planet.
Masterbilt Craftsmanship
When I requested a test sample from Galoc, I learned the Master Agent shoulder holster is built to order. The craftsmen at Galco spend a lot of time and take great pride in turning out what is essentially a hand-crafted shoulder rig.
The Masterbilt holster line is the high end of Galco’s already high-quality leather gear lineup. According to Galco, these holsters are constructed using premium leather and molded by their most experienced craftsmen before being dried on a solid form to ensure precise fit.
When I received my sample weeks later, it was very obvious that wasn’t marketing hype. The craftsmanship and attention to detail were apparent the moment I opened the package.
Construction and Retention
The Master Agent shoulder holster is hand-molded black leather, with a beautifully shined exterior. The open-front design does not use a retention strap, nor does it need one. Because each holster is made to fit a specific handgun, they are precisely molded around the requested revolver’s cylinder.
That custom-level precision securely holds your firearm in place, but a retention screw allows users to fine-tune retention for a smooth and secure draw. The holster pouch is lined with smooth tan leather, protecting the finish of revolvers. That’s an especially nice touch for more delicate polished blue finishes.
Diagonal Draw Position
Galco designed the Master Agent to hang at what they deemed a “diagonal draw” position, where the revolver’s grip is down and the muzzle points slightly up toward the armpit. Galco chose this orientation as the best to balance concealability and fast draw speed.
I found the design has another benefit as well. For shooters, like me, whose shoulders don’t move like they once did, a traditional muzzle-down or horizontal shoulder holster positions the grip too far behind the body. That reach makes it difficult to effectively and safely grip the revolver.
The butt-forward diagonal draw puts the revolver within much easier reach. That combined with no retention snap makes the draw simple. Once you have a solid grip, just pull slightly downward to clear the gun.
Harness & Belt Attachment
The Master Agent is a cleverly designed two-piece adjustable strap harness with a single anchor point on the opposite side.
Galco provides two attachment options. The suspender-style clasp can be clamped directly to your trousers, or the harness can be clipped into a supplied leather belt loop attachment.
The simple attachment systems make the Master Agent one of the easiest should holsters I’ve worn to put on and remove quickly.
Why the Master Agent Is a Standout Revolver Shoulder Holster
Having worn the Galco Masterbilt Master Agent Shoulder Rig for a few days, I’m impressed. I’m happy to have taken the weight of my S&W 638 off my waist and realized after several hours at a church function that I didn’t even notice the shoulder holster and revolver were there.
Comfort is a strong point. Shoulder holsters distribute the firearm’s weight across the shoulders rather than concentrating it on the beltline, which can make a big difference during long periods of carry.
The diagonal draw design works extremely well, especially for those of us whose shoulders may not have the same flexibility they once did. The position keeps the revolver grip within easy reach and allows a solid firing grip without having to fight the holster or clear a retention strap.
Keep in mind that shoulder holsters, regardless of muzzle position in the holster, are not allowed to be drawn from on public ranges. An inherent factor of the design is that you will end up sweeping people standing either behind you or to your sides as part of the draw. Be sure to practice your draw with an unloaded firearm during dry-fire training.
The built-to-order construction, premium leather and thoughtful design make the Galco Masterbilt Master Agent Shoulder Rig a serious option for anyone who prefers carrying a revolver in a shoulder holster. It may not be the least expensive rig on the market, but quality leather gear rarely is.
The Galco Masterbilt Master Agent promises a lifetime of service with simple care. The Masterbilt line clearly represents the high end of Galco’s leather gear, and the attention to detail shows. MSRP of models built for K-frame and J-frame S&Ws, Speed, Security and Service Six Rugers, and Charter Arms’ Undercover series is $280. There are also two-gun models available for $498.
