Description
Back in the late 1950s, Steve McQueen carried a cut-down lever gun on Wanted: Dead or Alive, and that oddball sidearm became more famous than the show itself. Henry Repeating Arms builds the Big Boy Mare's Leg H006GML as a faithful tribute to that original, right down to the American walnut furniture shaped to match the TV gun. It fires with all the speed of a lever action but rides in a holster like a pistol, and there is really nothing else on the wall quite like it.
What Makes the Big Boy Mare's Leg Special
The heart of this gun is the same polished hardened brass receiver and famously crisp action found on Henry's full-size Big Boy rifles. The 12.9 inch octagon blued steel barrel gives it that classic frontier profile, and the large loop lever makes cycling fast and easy, even with gloves on. Chambering is .44 Magnum with the option to run softer-recoiling .44 Special, which makes range days a lot more pleasant and keeps ammo choices flexible. Sights are a brass bead up front paired with a fully adjustable semi-buckhorn rear with diamond insert, and the receiver comes drilled and tapped if you ever want to mount optics.
Loading the Henry Mare's Leg H006GML
This is the Side Gate version, and that matters. You can top off the five-round tube magazine through the loading gate on the receiver without breaking your grip, then use the removable magazine tube to unload safely at the end of the day. It is the best of both loading systems in one gun.
A Lever Action Pistol Built in the USA
At 25 inches overall and about 5.79 pounds, the Mare's Leg is compact, well balanced, and a genuine conversation starter. Whether it ends up as a working range gun, a companion piece to a Big Boy rifle, or the centerpiece of a Western collection, this Henry earns its spot.

Frequently Asked Questions
Can the Henry Big Boy Mare's Leg shoot both .44 Magnum and .44 Special?
Yes, it handles both. Full-power .44 Magnum loads give you serious punch, while .44 Special runs noticeably softer and cheaper for casual range sessions. Being able to swap between the two is one of the best parts of owning a .44 lever gun.
How do you load the Mare's Leg H006GML?
Two ways. This Side Gate model lets you feed rounds through the loading gate on the brass receiver to keep the five-round tube topped off, and it also retains Henry's removable magazine tube so you can unload safely without cycling every round through the action.
Is the Henry Mare's Leg based on a real gun from TV?
It is. Steve McQueen carried a cut-down lever action nicknamed the Mare's Leg on the Western series Wanted: Dead or Alive, and Henry patterns the walnut stock on this model after the gun from the show. It has been a favorite with Western fans and collectors ever since.
Can I mount an optic on the Big Boy Mare's Leg?
The receiver comes drilled and tapped from the factory, so adding a scope base or rail is straightforward. Most owners stick with the brass bead front and adjustable semi-buckhorn rear sights, which suit the gun's classic character, but the option is there if you want glass.
