Description
The Henry Big Boy Revolver 357 Gunfighter is a revolver chambered in 357 Magnum/.38 Spl with a 4-inch barrel.

Henry Big Boy Revolver 357 Gunfighter Overview
Henry’s single action revolvers are built to match its famous lever guns, with polished blued steel and American walnut grips. They use a transfer bar safety so they can be carried with all six chambers loaded, and they come with interchangeable front sights for fine-tuning point of aim. Revolvers remain popular because they are simple to operate and very forgiving. There is no slide to rack and no magazine to seat, and a misfire is cleared by simply pulling the trigger again.
The trade-off is capacity and reload speed, so a few speedloaders or moon clips are worth adding. Practice the double action trigger pull regularly, because a smooth, steady press is the key to accuracy with any wheelgun.
Design and Features
Henry recommends it for target, collector. Extras include interchangeable high/medium/low. Every Henry is made in America and backed by Henry’s lifetime warranty and well-known customer service. For carry, choose a holster that covers the trigger guard and holds the cylinder snugly, and practice reloading with speedloaders or speed strips until the motion is smooth. Keep the cylinder and forcing cone clean, since lead and carbon build up there first, and inspect the timing occasionally by watching the cylinder lock up as the hammer falls.
Handling and Carry
Henry’s lever actions are known for their slick, smooth actions right out of the box, and this one is a pleasure to shoot and carry.
Trigger and Controls
The trigger breaks cleanly, and the transfer bar safety adds peace of mind.
Sights and Optics
The factory sights give a clear, quick sight picture, and an optic-ready slide (where fitted) lets you add a red dot whenever you are ready.
The 357 Magnum/.38 Spl Cartridge
The 357 Magnum/.38 Spl offers a good balance of power, accuracy, and recoil for its intended use.
Setup and Accessories
Pick a holster made for your revolver’s frame size and barrel length, and add speedloaders or speed strips so you can reload quickly.
Ownership Tips
Read the owner’s manual fully before your first range trip, and keep the manual, box, and receipt with your records for warranty service and resale. Unload the revolver and confirm it is empty before cleaning. Field-strip it according to the owner’s manual, scrub the bore with a brush and patches, and wipe carbon from the breech face and slide rails. Apply a light coat of quality gun oil to the contact points, and wipe the exterior with a lightly oiled cloth before storage.
