The Big Boy Mare's Leg is Henry's purpose-built lever-action pistol configuration, offering the classic Big Boy feel in a compact format. It is chambered for .357 Magnum and also accepts .38 Special, giving the shooter flexible ammunition options for the range or field.
Construction highlights include a polished brass receiver, brass forend cap/barrel band, and brass buttplate paired with a blued round-profile steel barrel. The walnut forearm and cut-down straight-grip walnut stock complete the traditional look and solid handling.
Sighting is straightforward with a brass-bead front and an adjustable semi-buckhorn rear. The action uses a large-loop lever for easy manipulation. Feeding is via a tubular magazine only, with a removable inner brass follower and knurled end cap; there is no side loading gate. Ejection is to the right.
This model features a 12.9 inch barrel and a 5+1 capacity. The tang is marked with model code H006MML, and the barrel shows the Bayonne, NJ address with Made in USA marking. The package is rounded out by the leather Mare's Leg scabbard and the original Henry box.
