Henry Big Boy Mare’s Leg H006GML .44 Mag/.44 Spl 12.9″

Description

The Henry Big Boy Mare’s Leg H006GML .44 Mag/.44 Spl 12.9″ is a compact lever-action pistol that packs serious punch in a handy package. Chambered for .44 Magnum and .44 Special, it features a 12.9-inch octagon blued steel barrel, polished hardened brass receiver, and an American walnut pistol-grip stock. The large loop lever and tubular magazine keep the classic lever-action feel, while the brass bead front sight and adjustable semi-buckhorn rear sight make it easy to get on target. A transfer bar safety adds modern peace of mind. This is the kind of gun that turns heads at the range and rides easy in a scabbard.

Key Features

• Octagon Blued Steel Barrel (12.9″) – Why it matters: The longer barrel gives you better velocity and sight radius than a typical pistol, making it more accurate at moderate distances while still being compact enough to handle easily.
• Polished Hardened Brass Receiver – Why it matters: Brass is tough and corrosion-resistant, plus it gives the gun that classic Western look that stands out in any collection. It also adds a bit of weight up front to help steady your aim.
• American Walnut Pistol-Grip Stock – Why it matters: The pistol grip gives you a more natural, secure hold than a straight stock, especially when shooting hot .44 Magnum loads. Walnut is durable and looks good even after years of use.
• Large Loop Lever – Why it matters: The oversized loop lets you work the action quickly, even with gloved hands. It’s a nod to the old Western gunfighters and makes the gun more fun to shoot fast.
• Transfer Bar Safety – Why it matters: This modern safety prevents the gun from firing unless the trigger is pulled, even if the hammer is dropped. It lets you carry the gun safely with a round in the chamber, which is a big deal for a lever gun.

Who It’s For

This Henry Big Boy Mare’s Leg is for shooters who want something different from the usual pistol. It’s great for cowboy action shooting, plinking, or just showing off at the range. New gun owners will appreciate the safe transfer bar system, while experienced shooters will love the classic lever-action feel. If you’re a fan of Western movies or just want a compact .44 that’s easy to carry, this one’s for you.

Pros & Cons

• Pros: Accurate for a pistol; classic looks; easy to shoot with .44 Special; large loop lever is fun to use; transfer bar safety adds peace of mind.
• Cons: The brass receiver is heavy, so it’s not a lightweight carry gun. Also, the 12.9″ barrel means it won’t fit in a standard holster—you’ll need a scabbard or a custom rig.

According to Henry specs, the Mare’s Leg is designed to run reliably with both .44 Magnum and .44 Special loads, giving you flexibility at the range.

FAQ

Is the Henry Big Boy Mare’s Leg legal to own without a tax stamp?

Yes. Because it has a 12.9″ barrel and a pistol grip stock, the ATF classifies it as a pistol, not a short-barreled rifle. You can buy it like any other handgun, no NFA paperwork required.

Can I shoot .44 Special in this gun?

Absolutely. The Henry Big Boy Mare’s Leg is chambered for both .44 Magnum and .44 Special. Shooting .44 Special gives you less recoil and muzzle blast, making it great for practice or plinking.

What kind of accuracy can I expect?

The 12.9″ octagon barrel and adjustable sights make it surprisingly accurate for a pistol. Many shooters report 2-3 inch groups at 25 yards with good ammo. The longer sight radius helps a lot.

Does it come with any accessories?

It ships with a manual and a cable lock. No case or extra sights are included, but it’s ready to shoot out of the box.
