Description
Henry built its name on lever-action rifles, so when they finally stepped into the wheel gun world, they made sure it looked and felt like a Henry. The Big Boy Revolver is a traditional double-action/single-action six-shooter chambered for .357 Magnum, which means it also runs .38 Special all day long. The deep polished bluing, mirror-bright brass trigger guard, and genuine American walnut grip panels give it the kind of old-school character that would look right at home in a Wild West storefront, while the transfer bar safety keeps the design thoroughly modern where it counts.
Why the Gunfighter Grip Version Stands Out
This model wears the square Gunfighter-style grip, the fuller of the two grip options Henry offers on this revolver. It fills the hand and gives you more to hang onto when you step up from soft .38 target loads to full-power .357 Magnum, and the extra purchase makes double-action work noticeably easier to control. At roughly 34 ounces with a 4 inch barrel and 9.5 inch overall length, there is enough steel here to soak up recoil without turning it into a boat anchor on your hip.
Sights You Can Tune to Your Load
The rear sight is a fixed notch machined right into the frame, paired with a screw-on ramped post up front. Henry includes three front sight heights, so you can swap posts to match your point of impact to your preferred load, a thoughtful touch you do not usually see on fixed-sight revolvers in this class.
A Natural Partner for Your Big Boy Rifle
If you already run a Big Boy lever gun in .357, this revolver completes the pair the old-fashioned way: one cartridge feeding both your rifle and your sidearm. Whether you are punching paper, plinking with cheap .38s, working cowboy matches, or just adding Henry's first revolver to the collection, the H017GDM delivers the fit, finish, and craftsmanship folks expect from the brand. It is a proper six-gun, built the way six-guns used to be built.

Frequently Asked Questions
Can the Henry Big Boy Revolver shoot .38 Special as well as .357 Magnum?
Yes. Like any revolver chambered in .357 Magnum, it safely fires .38 Special from the same cylinder. That makes it easy on the wallet for practice and plinking with .38s while keeping full-power .357 loads on hand when you want them.
What is the difference between the Gunfighter and Birdshead grip versions?
The Gunfighter grip on this model is the square, fuller-sized option that gives you more real estate to hold onto, which most folks prefer for range work and hotter .357 loads. The Birdshead version has a rounded, more compact grip aimed at easier carry. Same frame, barrel, and internals on both.
Are the sights on the Big Boy Revolver adjustable?
The rear sight is a fixed notch cut into the frame, so there is no dial-in adjustment there. Instead, Henry ships three front sight posts in different heights that screw on and off, letting you regulate the point of impact to match your preferred ammo. It is a simple, rugged system that holds zero well.
Does the Henry Big Boy Revolver pair with a .357 lever-action rifle?
That is a big part of the appeal. Henry designed this revolver as a natural sidekick to their Big Boy lever guns in .357 Magnum, so you can feed both firearms from the same ammo box. The shared walnut, bluing, and brass styling means they look like a matched set too.
