Description
Henry built its name on lever-action rifles, so when they finally made a revolver, they did it their way: polished blued steel, genuine American walnut, and a look that would fit right in behind the counter of an 1880s general store. The Big Boy Revolver H017BDM is a traditional double-action/single-action six-shooter chambered in .357 Magnum, which means it also runs .38 Special all day long for cheaper, softer-recoiling range sessions. The rounded birdshead grip is the standout here. It fills the hand more than you'd expect, gives the gun a compact profile, and there's a polished brass trigger guard peeking out around the walnut that pairs beautifully with the deep blue finish.
What the Big Boy H017BDM Brings to the Range
At around 34 ounces with a 4-inch round blued barrel, this revolver has enough heft to soak up magnum recoil without feeling like a boat anchor on your hip. The double-action pull is smooth, the single-action break is crisp, and the sight setup is smarter than most fixed-sight wheelguns. The rear notch is machined right into the frame, but the front is a screw-on ramped blade, and Henry includes three heights so you can match point of aim to point of impact with your preferred load. The cylinder pops out quickly too, which makes cleanup after a long day of shooting a whole lot less tedious.
A Natural Partner for Your Henry Lever Gun
If you already own a Big Boy rifle in .357, this is the obvious sidearm to feed from the same ammo box, and plenty of folks buy it for exactly that reason. Despite the vintage styling, it's not stuck in the past. A transfer bar safety keeps the firing pin off a loaded chamber unless the hammer is cocked and the trigger is pulled, so you can load all six with confidence. Whether it ends up punching paper, riding along on a cowboy-style rig, or holding a place of pride in the safe, this is a genuinely well-finished revolver with the fit and attention to detail Henry is known for.

Frequently Asked Questions
Can the Henry Big Boy Revolver shoot .38 Special as well as .357 Magnum?
Yes. Since it's chambered in .357 Magnum, it safely fires .38 Special from the same cylinder. A lot of owners run .38s for relaxed, low-cost range time and save the magnums for when they want the full experience. It also shares ammo with .357 lever guns like Henry's own Big Boy rifle.
Is the H017BDM single action only, or can I shoot it double action?
It's a traditional double-action/single-action revolver, so you get both. You can cock the hammer for a crisp single-action break or simply pull the trigger for double-action fire. Despite the old-west styling, it handles like a modern DA/SA wheelgun.
Is it safe to carry the Big Boy Revolver with all six chambers loaded?
Yes. Henry equipped this revolver with a transfer bar safety, which means the firing pin can't contact a cartridge unless the hammer is fully cocked and the trigger is pulled. That's a modern feature the original birdshead-gripped revolvers of the 1870s never had, and it lets you load all six with confidence.
What are the extra front sights for on the Henry Big Boy H017BDM?
Henry includes three screw-on front sight blades in high, medium, and low heights. Since the rear notch is fixed in the frame, swapping the front blade lets you regulate elevation so your point of aim matches your point of impact with your preferred load. It's a simple, practical touch you don't often see on fixed-sight revolvers.
