Henry H12 Provider .357 Magnum 20-Inch Rifle

The Henry H12 Provider .357 Magnum 20-Inch is a lever-action rifle chambered in .357 Magnum / .38 Special.

Introduced for Henry Repeating Arms’ 2026 lineup, the Provider uses the company’s H12 pistol-caliber centerfire action in a full-length 20-inch rifle configuration.

In addition, Model H012PG-357 combines a round blued-steel barrel, blued-steel receiver, checkered American walnut furniture and a 10-round tubular magazine.

The fully adjustable semi-buckhorn rear sight, brass-bead front sight, drilled-and-tapped receiver and transfer-bar safety complete the principal factory specification.

Henry H12 Provider .357 Magnum 20-Inch Overview

The Henry H12 Provider .357 Magnum 20-Inch represents the longer rifle configuration within Henry’s new Provider family.

The H12 designation identifies Henry’s pistol-caliber centerfire lever-action platform.

Meanwhile, the Provider designation separates the 20-inch rifle from the shorter 16.5-inch Protector Carbine.

Furthermore, Henry equips the Provider with a longer tubular magazine than the Protector.

As a result, the .357 Magnum Provider carries a published 10-round capacity while retaining traditional walnut furniture and blued-steel construction.

H12 .357 Magnum Chambering

The rifle is chambered in:

.357 Magnum / .38 Special

Henry lists both cartridges in the factory model designation.

Therefore, the primary WooCommerce chambering can be written as:

.357 Magnum / .38 Special

while the SEO keyphrase uses .357 Magnum as the main cartridge term.

For more informational firearm reference pages, browse the Gunvexa firearm reference catalog.

For exact identification, the chambering should also be confirmed through the markings on the individual barrel.

.357 Magnum and .38 Special Compatibility

Henry’s H12 documentation identifies the platform as compatible with both .357 Magnum and appropriate .38 Special ammunition.

The manufacturer’s manual also contains cartridge-specific guidance for .38 Special use.

For a product specification page, however, it is sufficient to list the factory chambering as:

.357 Magnum / .38 Special

and direct owners to the Henry manual for detailed ammunition requirements.

20-Inch Provider Barrel

The Provider uses a 20-inch barrel.

This length represents one of the clearest differences between the Provider and Protector.

Henry’s 2026 announcement describes all Provider rifles with 20-inch barrels.

By comparison, Protector Carbines use shorter 16.5-inch barrels.

Therefore, 20-Inch should remain in the product title, focus keyphrase and SEO title for this exact configuration.

Round Blued-Steel Barrel

Henry identifies the barrel as:

Round Blued Steel

This specification distinguishes the Provider from Henry rifles using octagonal barrels, stainless finishes, hard-chrome treatments or Cerakote.

The traditional round profile also matches the rifle’s American walnut furniture.

Consequently, both barrel shape and finish should appear in the technical specification table.

Non-Threaded Barrel Configuration

A significant Provider characteristic is its non-threaded barrel.

Henry specifically contrasts the Provider’s 20-inch non-threaded barrel with the shorter threaded barrel used on Protector Carbines.

Therefore, the Provider should not be described as threaded simply because the H12 Protector uses that feature.

For this page, use:

Muzzle: Non-threaded factory configuration.

1:16 Twist Rate

The .357 Magnum/.38 Special H12 Provider uses a 1:16 twist rate.

Henry publishes this value directly for Model H012PG-357.

The .44 Magnum H12 Provider uses a different 1:20 specification.

Consequently, the twist rate provides another useful technical distinction between the two H12 chamberings.

Blued-Steel Receiver

The receiver is constructed from steel.

Henry applies a traditional blued-steel finish to the receiver.

This gives the central action a dark appearance matching the barrel.

Furthermore, it distinguishes the Provider from Henry configurations using brass, color-case-hardened steel or hard-chrome finishes.

Matte Bluing Appearance

Henry’s launch information describes Protector and Provider receivers as using a matte blued-steel finish.

The subdued finish complements the walnut furniture without producing the brighter surface associated with polished metal treatments.

Therefore, the exterior can accurately be described as a traditional blued-steel and walnut configuration.

Lever-Action Operation

The H12 Provider uses a lever-action repeating mechanism.

The operating lever is positioned beneath the receiver.

Cycling the lever operates the bolt and feeds cartridges from the tubular magazine.

An exposed hammer remains visible at the rear of the receiver.

Together, these characteristics form the traditional mechanical layout of Henry’s H12 centerfire lever-action platform.

Exposed Hammer

The action incorporates an exposed hammer.

This is a recognizable characteristic of the H12 architecture.

The hammer works together with Henry’s transfer-bar safety system.

Therefore, the exposed hammer and transfer-bar system should be documented separately when creating a complete technical reference.

Transfer-Bar Safety

Henry lists the H12 Provider with a transfer-bar safety.

This is the factory safety system specified for Model H012PG-357.

Consequently, the correct WooCommerce safety field is:

Transfer Bar.

Tubular Magazine System

The Provider uses an under-barrel tubular magazine.

The magazine runs beneath the full 20-inch barrel.

Its additional length allows the Provider to carry more cartridges than the shorter Protector Carbine.

Therefore, magazine type and capacity are important distinctions between the two configurations.

Ten-Round Capacity

Henry publishes a 10-round capacity for the H12 Provider in .357 Magnum/.38 Special.

The 10-round tube is part of the full-length Provider configuration.

By comparison, the compact Protector uses a shorter magazine system.

For your main WooCommerce capacity field, use:

10 rounds.

H012 Side-Gate Action Family

The H12 belongs to Henry’s H012 centerfire lever-action family.

Henry maintains a dedicated H012 Series Side Loading Gate owner’s manual covering the underlying H12 action architecture.

Therefore, the Provider can be documented within Henry’s current side-gate H12 family while keeping the exact H012PG-357 dimensions and specifications tied to the 2026 Provider sheet.

American Walnut Stock

The rifle uses genuine American walnut furniture.

Henry specifies American walnut directly for Model H012PG-357.

Natural wood grain and coloration can vary between rifles.

Therefore, the exact stock appearance should be documented using photographs of the individual product.
