The Henry Big Boy 4" .357 Magnum revolver is a classic .357 Magnum/.38 Special six-shooter built for shooters who appreciate traditional wheelgun handling and versatility. With a 4-inch barrel, this double-action/single-action revolver delivers the kind of reliable, straightforward performance that works equally well at the range, in the field, or in a display case for collectors who value American-made craftsmanship. At 35 ounces and 9.5 inches overall, it balances pointability with solid heft—manageable enough for extended shooting sessions, substantial enough to inspire confidence in your grip.
The polished blued steel frame and round blued barrel give the Big Boy a refined, professional appearance without sacrificing durability. American walnut grips provide both comfort and that timeless look that distinguishes quality revolvers. A transfer bar safety mechanism adds a layer of protection during carry and handling. The fixed notch rear sight and screw-on front post sight keep things simple and reliable, and Henry's interchangeable front sight system (high, medium, and low options) lets you dial in your sight picture for your preferred shooting distance or load.
Whether you're reaching for a trusted .357 Magnum wheelgun for sport shooting, home defense, or simply appreciate the mechanical elegance of a well-made revolver, the Big Boy delivers the fundamentals without complication. The ability to shoot both .357 Magnum and .38 Special ammunition gives you flexibility and cost-effective practice options. This is a handgun that works without trending, speaks for itself, and has been trusted by shooters for generations.

Frequently Asked Questions
Can I shoot .38 Special ammunition in this .357 Magnum revolver?
Yes. The Henry Big Boy is chambered for both .357 Magnum and .38 Special, so you can safely fire either cartridge. This gives you flexibility for practice, variety in shooting dynamics, and often a lower cost-per-round option with .38 Special loads.
What sights come with this revolver?
The Big Boy includes a fixed notch rear sight and a screw-on front post. The revolver comes with interchangeable front sight options in high, medium, and low heights, so you can choose the configuration that works best for your sight picture and shooting distance.
Is this revolver suitable for concealed carry?
At 9.5 inches overall and 35 ounces, the Big Boy is on the larger side for concealed carry. It's better suited to open carry, range use, field work, or home defense scenarios where a full-sized revolver is practical.
What does the transfer bar safety do?
The transfer bar safety prevents the firing pin from striking the primer unless the trigger is fully pressed. This adds an extra layer of protection during handling and carry, reducing the risk of an accidental discharge from impact or snag.
