Henry Mare's Leg .357 Magnum Lever Action
About this product
The Henry Mare's Leg is a lever-action pistol — a shortened version of Henry's Big Boy rifle action, built with a 12.9-inch barrel and a stub buttstock instead of a full-length stock, chambered in .357 Magnum and .38 Special. It's the style popularized on television as a saddle-carried, quick-handling lever gun, and because it leaves the factory built and configured as a handgun, it isn't classified or regulated as a short-barreled rifle — it transfers through your FFL dealer as a pistol.
What is it used for?
It's a range and collector piece more than a practical defensive handgun — the lever action and long sight radius relative to a typical pistol make it a fun, distinctive shooter for .357 Magnum and .38 Special, and its television-famous silhouette draws collectors who want a Henry lever gun in a compact, handgun-legal format. The brass receiver, walnut furniture, and octagonal barrel are shared with Henry's full-size Big Boy Classic rifle, so it carries the same build quality and finish in a shortened package.
How does it compare to the full-size Big Boy?
Mechanically it's the same lever-action system, same brass receiver, same walnut and octagonal barrel styling as the Big Boy Classic — what's different is the 12.9-inch barrel and stub buttstock in place of a rifle-length barrel and full stock. That shorter format is what makes it a pistol rather than a rifle in the eyes of the law, and it's also what gives up the longer sight radius and stock support you'd get from the full-size gun.
What's it chambered in?
.357 Magnum and .38 Special, interchangeably, with a 5-round capacity on .357 Magnum and 6 rounds on .38 Special in the tubular magazine. That dual-caliber flexibility is standard for Henry's .357 lever guns — you can practice with cheaper .38 Special and carry or hunt with full-power .357 Magnum through the same gun.
Who is this not for?
If you're looking for a practical concealed-carry handgun, this isn't it — it's long, distinctive, and built for range use and collecting rather than discreet carry. It's also not the right pick if you want a rifle-length sight radius and shoulder stock, since the whole point of this configuration is the shortened, pistol-legal format. And if recoil management matters to you more than novelty, a standard-frame revolver in the same chambering will generally be easier to shoot fast and accurately than a lever gun held at arm's length.
Does it work in California?
It transfers as a handgun through your FFL dealer, which means California's handgun roster rules apply — confirm roster status with your dealer before ordering, since not every handgun model and configuration clears the state's approved list. Standard California handgun purchase rules also apply: the 10-day wait, DROS, and Firearm Safety Certificate. See California gun laws for what to expect, and pair this with something like the CZ 83 if you're comparing other FFL-transfer handguns while you sort out roster questions.
Is it worth $772.49?
For Henry's build quality — brass receiver, walnut furniture, the same fit and finish as the Big Boy Classic — in a distinctive, dual-caliber handgun format, this is priced in line with what Henry lever guns generally run. It's a want, not a need, purchase — buy it because you want the Mare's Leg specifically, not as a general-purpose defensive handgun.

Frequently asked questions
- Is the Mare's Leg legal to own as a handgun?
- Yes — because it ships from the factory built as a handgun rather than cut down from a rifle, it doesn't fall under short-barreled rifle regulations and transfers as an ordinary pistol through your FFL dealer.
- What calibers can I shoot through it?
- Both .357 Magnum and .38 Special interchangeably, with 5-round capacity on .357 Magnum and 6-round capacity on .38 Special.
- How is this different from Henry's Big Boy rifle?
- Same lever-action mechanism, brass receiver, and walnut/octagonal barrel styling, but with a 12.9-inch barrel and stub buttstock instead of a full rifle-length barrel and stock, which is what makes it a pistol legally.
- Is it California roster-approved?
- Confirm current roster status with your dealer before ordering — handgun roster approval can change, so don't assume it clears the list without checking at time of purchase.
- What sights does it come with?
- An adjustable buckhorn rear sight and a brass bead front sight, standard on this model.
