The Comprehensive Guide To The Stevens Model 311 Double-Barrel Shotgun In 2026

Disambiguation Note: This guide focuses exclusively on the J. Stevens Arms Company Model 311 side-by-side shotgun, a legendary American double-barrel firearm, and does not refer to unrelated industrial machinery or consumer goods sharing the same numerical designation.

For generations, the Stevens Model 311 has served as a benchmark of utilitarian American shotgun design. Manufactured primarily under the Stevens, Savage, and Springfield brands from the early 1930s until production ceased in the late 1980s, this side-by-side shotgun earned a reputation as an unpretentious, durable, and reliable working gun. As collectors, traditional hunters, and cowboy action shooters continue to seek out dependable vintage double-guns in 2026, understanding the technical specifications, historical evolution, maintenance protocols, and operational nuances of the Model 311 is essential for safe handling and long-term preservation.

Historical Evolution and Manufacturing Eras

The lineage of the Stevens Model 311 traces back to Stevens Arms' long-standing tradition of producing affordable, high-utility shotguns. Following Savage Arms' acquisition of Stevens in 1920, the company streamlined its double-barrel offerings, culminating in the formal introduction of the Model 311 blueprint in the 1930s.

Unlike fine English or European side-by-sides characterized by hand-engraved sideplates and delicate wood-to-metal fits, the Model 311 was engineered explicitly for mass production, strength, and field durability. Over its multi-decade run, the firearm underwent several manufacturing shifts:

• Pre-War Production (1930s–1942): Characterized by solid frame construction, checkered walnut stocks, and blued steel finishes. Production was temporarily halted or diverted for military training needs during World War II.
• Post-War Expansion (1946–1960s): Marked by widespread commercial distribution, often sold under hardware store brand names (such as Savage/Stevens "Store Brands" like Revelation, Ranger, or Western Auto).
• Late Production Era (1970s–1989): Transitioned to utility hardwood stocks (frequently birch with a synthetic dark stain), simplified internal coil springs, and standard utility chokes before Savage ultimately wound down traditional side-by-side production.

Technical Specifications and Design Architecture

The Stevens Model 311 is a break-action, hammerless side-by-side shotgun utilizing a boxlock action design. Unlike sidelock mechanisms, the boxlock houses all spring-driven components within the frame, offering superior structural rigidity and simplified maintenance.

Internal Mechanics and Lockwork

The lockwork of the Model 311 relies on robust coil springs rather than fragile leaf springs. This choice significantly enhances the service life of the shotgun under heavy field use. The dual triggers are non-selective; the front trigger consistently fires the right barrel, while the rear trigger fires the left barrel. Extraction is handled by a mechanical extractor that lifts the cartridge hulls clear of the chambers upon breaking the action, avoiding the complexity of spring-loaded ejectors.

Identifying Your Stevens Model 311: Date Codes and Variants

Because millions of these shotguns were produced across nearly six decades without standard serial number databases that cover every year, dating a Model 311 requires examining specific physical markers and Savage/Stevens date codes.

Savage-Stevens Date Code Stamp System

From 1949 through 1970, Savage Arms stamped a small circle containing a letter and a number onto the lower frame near the trigger guard or on the barrel lug.

• A = 1949
• B = 1950
• (Continuing alphabetically through the alphabet, omitting letters like O and Q)
• The accompanying number indicates the specific inspection or production batch year.

Major Model Variations

• Model 311A: The most common iteration, featuring standard double triggers and a pistol grip stock.
• Model 311R (Riot): A short-barreled variant (typically 18 or 20 inches) produced for law enforcement and security applications.
• Model 5100: Structurally identical to the 311, utilized during the mid-century manufacturing periods across various branding designations.
• Fox Model B: Produced by Savage/Stevens utilizing the Model 311 action framework but branded under the historic A.H. Fox name with slightly upgraded cosmetic appointments.

Ammunition Considerations and Ballistic Safety in 2026

Operating vintage shotguns requires strict adherence to modern ammunition safety standards, particularly concerning steel shot and high-pressure loads.

Steel Shot Compatibility

The vast majority of vintage Stevens Model 311 shotguns feature fixed Full or Modified chokes with traditional thin-walled carbon steel barrels. Firing modern steel shot through tight fixed chokes (especially Full chokes) risks scored barrels, barrel bulging, or catastrophic failure due to steel's lack of compressibility compared to lead. For waterfowl hunting or regulated areas requiring non-toxic shot, owners should utilize bismuth, tungsten-polymer, or low-pressure specialty non-toxic loads, or have a qualified gunsmith open the chokes.

Chamber Length Verification

Older 12-gauge Model 311 shotguns were chambered exclusively for 2-3/4 inch shells. Forcing modern 3-inch magnum shells into a 2-3/4 inch chamber creates an obstruction that dramatically spikes chamber pressure, risking personal injury and severe firearm damage. Always verify the chamber length using precision gauge measurement tools before heading to the field.

Step-by-Step Field Stripping and Maintenance Guide

Routine maintenance keeps the robust Model 311 functioning reliably for decades. Because boxlock actions accumulate debris, unburned powder, and moisture over time, periodic cleaning of the internal lockwork is vital.

1. Safety Verification: Ensure the firearm is unloaded by opening the action and inspecting both chambers. Close the action gently.
2. Remove the Forend: Pull the forend latch lever (located underneath the forend wood) outward and rotate or pull the forend away from the barrels.
3. Detach the Barrels: Push the top-tang lever fully to the right, support the barrels with one hand, and swing the stock downward to disengage the barrel lugs from the receiver hook.
4. Clean the Bores: Use a cleaning rod with a properly sized bronze brush and quality solvent to remove plastic fouling and powder residue from the barrels. Finish with light gun oil.
5. Inspect the Receiver Face: Wipe down the breech face, firing pin bushings, and locking lugs. Apply a thin film of gun grease to the hinge pin and locking bolt surfaces to prevent metal-on-metal galling.
6. Reassembly: Reverse the disassembly steps, ensuring the forend iron snaps securely back onto the barrel loop. Do not force any components; proper alignment of the hinge pin is essential.

Comprehensive Pros and Cons

Frequently Asked Questions

What ammunition can I safely shoot through my vintage Stevens Model 311?

Standard 2-3/4 inch low-brass lead target loads or traditional game loads are ideal. Avoid high-pressure modern magnum loads and hard steel shot unless your specific barrels have been professionally evaluated and cleared or modified by a gunsmith.

How do I determine the exact manufacture year of my Stevens 311?

Check the lower metal frame near the trigger guard for a small stamped circle containing a letter code corresponding to Savage-Stevens production records from 1949 to 1970. If no code is present, dating relies on evaluating physical attributes, roll-marks, and address stamps with reference guides.

Are Stevens 311 shotguns safe for modern Cowboy Action Shooting?

Yes, the Model 311 is exceptionally popular in Single Action Shooting Society (SASS) competitions due to its robust dual-trigger design and reliable lockwork. Many competitors have action work performed to smooth the opening lever and lighten the springs.
