Wyoming Firearms History

Wyoming sits at an interesting intersection in American firearms history. It is simultaneously one of the most gun-permissive states in the country today and a place where early settlers — contrary to the mythology — actually passed some of the West's earliest municipal firearms regulations. The full picture is more complicated and more interesting than either the "Wild West" romanticists or the gun-control advocates tend to admit.

Key milestones in Wyoming's firearms history from territorial period to present day

The state's relationship with firearms runs from Eastern Shoshone, Northern Arapaho, and Crow trade guns in the early 1800s through the mountain man era, cattle drives, the Johnson County War, two World Wars, and straight into a 21st-century legal environment that now allows any law-abiding adult — resident or visitor — to carry a loaded firearm without a permit. That arc did not travel in a straight line.

With roughly 578,000 people spread across 97,000 square miles, Wyoming is the least populated state in the nation. Firearms here are practical tools as much as political symbols — predator control on ranches, elk and pronghorn hunting, and genuine geographic isolation from emergency services make that reality concrete rather than rhetorical.

Wyoming had no Colonial Era in the Eastern sense. When English colonists were debating musket storage laws in Virginia, the land that would become Wyoming was the domain of:

• Eastern Shoshone
• Northern Arapaho
• Crow
• Lakota Sioux
• smaller bands whose access to European firearms fundamentally altered the balance of power

Fur Trade and Early Settlement

The fur trade era, roughly 1820 through the early 1840s, brought the first sustained European American firearms presence into Wyoming. Rendezvous sites in the Green River Valley — particularly near present-day Pinedale — became annual gathering points where trappers, tribal traders, and representatives of outfits like the Rocky Mountain Fur Company exchanged goods.

Flintlock rifles and trade fusils changed hands alongside beaver pelts. The 1825 and 1838 rendezvous on the Green River were among the largest gatherings on the continent, and firearms were a primary trade commodity.

Military Installations and Indian Wars

Fort Laramie, established as Fort William in 1834 and later renamed Fort John before the U.S. Army purchased it in 1849, became the most strategically significant military installation on the Northern Plains. The fort anchored the Oregon Trail corridor and served as the site of the Fort Laramie Treaty of 1851, which attempted — unsuccessfully over the long run — to define tribal territories and reduce conflict along the emigrant routes.

The subsequent Fort Laramie Treaty of 1868 ended Red Cloud's War and created the Great Sioux Reservation, though the discovery of gold in the Black Hills rendered the agreement functionally void within a decade.

The Bozeman Trail conflicts of the 1860s, particularly Red Cloud's War from 1866 to 1868, saw Wyoming forts — Fort Reno, Fort Phil Kearny, and Fort C.F. Smith — besieged in what amounted to a sustained guerrilla campaign. The Fetterman Fight of December 21, 1866, near Fort Phil Kearny killed all 81 U.S. soldiers under Captain William Fetterman in an ambush led by Crazy Horse and other Oglala and Cheyenne warriors. It remains the U.S. Army's worst defeat on the Northern Plains prior to Little Bighorn. The Army's Springfield Model 1866 trapdoor rifles and Sioux warriors armed with captured military weapons and traditional arms fought at close enough range that the tactical details of the engagement were later reconstructed from physical evidence on the ground.

Early Municipal Gun Control

Wyoming Territory was organized in 1869 — notable also as the year the territory granted women the right to vote, a first in American history. The territorial period brought cattle ranching on a massive scale, and with it the firearms culture of the open range.

Colt Single Action Army revolvers and Winchester Model 1873 lever-action rifles became standard equipment for cowboys, trail bosses, and the hired men who protected cattle herds from rustlers and predators.

The reality of firearms in Wyoming's early towns, though, cuts against the Hollywood version of history. University of Wyoming historian Phil Roberts documented that five of six early Wyoming town councils passed ordinances specifically banning the carrying of firearms — openly or concealed — within town limits.

Cheyenne enacted its firearms ordinance on September 30, 1867, just 88 days after General Grenville Dodge designated the townsite. Lusk passed a similar ordinance on August 1, 1898. Casper followed in 1897. Worland's town council — composed of cattlemen and pioneer businessmen — unanimously passed a gun-carry ban as only its ninth ordinance on May 9, 1906. The mythology of every man armed in every Wyoming town simply doesn't match the documentary record of what those early communities actually wanted.

Johnson County War

The Johnson County War of 1892 is Wyoming's most notorious firearms event. Large cattle operators, organized as the Wyoming Stock Growers Association, hired approximately 25 Texas gunmen and several association members to invade Johnson County and kill alleged rustlers and homesteaders who were competing with or stealing from the large ranches.

The invaders — known as the Regulators — killed Nate Champion and Nick Ray at the KC Ranch before being surrounded by hundreds of armed Johnson County settlers near the TA Ranch. The U.S. Cavalry from Fort McKinney intervened and arrested the invaders, but Governor Amos Barber — sympathetic to the large cattle interests — ensured that no one was ever prosecuted. The episode illustrated how thoroughly firearms and class conflict were intertwined in territorial Wyoming.

Wyoming achieved statehood on July 10, 1890. The state constitution ratified that year included Article 1, Section 24:

The right of the citizens to bear arms in defense of themselves and the state shall not be denied.

The language was direct and the intent clear — this was a state that expected its citizens to be armed.

The late 1890s brought the Ghost Dance movement and subsequent Wounded Knee Massacre of December 29, 1890 in neighboring South Dakota, but Wyoming's military installations remained on heightened alert. Fort Washakie, established in 1871 on the Wind River Reservation to protect the Eastern Shoshone from Lakota raids, remained an active post. Chief Washakie of the Eastern Shoshone — one of the most consistently U.S.-aligned tribal leaders in the West — was buried there in 1900 with full military honors, the only Native American tribal chief to receive that distinction from the U.S. Army.

By the 1890s, Buffalo Bill Cody had already built his Wild West show into an international phenomenon, and he established the town of Cody, Wyoming in 1896. His show's firearms exhibitions — featuring Annie Oakley and his own shooting demonstrations — shaped the global popular imagination of Wyoming and the West as a place defined by marksmanship. That cultural image, accurate or not, has had durable consequences for how Wyoming's gun culture is perceived both internally and externally.

Wyoming's small population meant its direct industrial contribution to American arms manufacturing was limited compared to eastern states, but its military installations and natural resources played real roles in both World Wars.

Military Installations and World Wars

Fort Francis E. Warren in Cheyenne — named after Wyoming's first state governor and Medal of Honor recipient Francis E. Warren — was one of the Army's major cavalry posts entering the 20th century. During World War I, it trained troops and served as a remount depot.

By World War II, it had transitioned to training infantry and was designated a prisoner of war camp, housing German POWs who worked on Wyoming farms and ranches. After the war, Warren transformed again — this time into one of the most consequential missile installations in the country.

Wyoming's oil and gas wealth, not its manufacturing base, defined its 20th-century economy. The state produced no major firearms manufacturers of national scale during this period, but it remained a significant consumer of sporting arms driven by its elk, deer, pronghorn, and bighorn sheep hunting. The Wyoming Game and Fish Department, established formally in its modern structure through the mid-20th century, managed one of the most diverse big-game hunting programs in North America, and the demand for high-powered rifles chambered in cartridges like .30-06 Springfield, .270 Winchester, and later the 7mm Remington Magnum kept Wyoming's sporting goods stores well-stocked.

Cold War Transformation

Evolution of Fort Francis E. Warren from cavalry post to nuclear missile installation

The Cold War reshaped Fort Francis E. Warren Air Force Base more dramatically than any other event in Wyoming's 20th-century military history. Redesignated Fort Francis E. Warren Air Force Base in 1947, it became home to the 90th Missile Wing, one of the largest intercontinental ballistic missile installations in the world. At peak deployment, Warren AFB controlled Minuteman III ICBMs spread across 12,600 square miles of southeastern Wyoming, northeastern Colorado, and western Nebraska. The base today remains an active ICBM installation — a reminder that Wyoming's relationship with firepower operates on scales well beyond sporting arms.

Federal Gun Control Response

The Gun Control Act of 1968 landed in Wyoming the same way it landed everywhere — federally mandated dealer licensing, the prohibition framework for prohibited persons, and the serialization requirements that still govern commerce today. Wyoming's legislature and congressional delegation were not enthusiastic participants. The state's two U.S. senators during this era reflected the broader western skepticism of federal firearms regulation that has only grown stronger in the decades since.

The Mulford Act-era debates and the broader national conversation around the Brady Handgun Violence Prevention Act of 1993 and the Federal Assault Weapons Ban of 1994 generated predictable opposition in Wyoming. The state's congressional delegation voted uniformly against the assault weapons ban. When the ban expired in 2004 without renewal, Wyoming had no state-level equivalent and made no move to create one.

The 2000s and 2010s saw Wyoming move deliberately toward one of the most permissive firearms legal environments in the country, piece by piece.

Constitutional Carry Evolution

Permitless carry for residents was enacted in 2011, allowing any Wyoming resident 21 or older who could legally possess a firearm to carry concealed without a permit. Wyoming retained its optional permit system for residents who needed one for reciprocity purposes while traveling to other states.

The 2021 session extended permitless carry to non-residents as well, effective July 1, 2021. Any adult who can legally possess a firearm under state and federal law can carry concealed in Wyoming without obtaining a permit. This made Wyoming one of a growing number of constitutional carry states, though the specific extension to non-residents placed it ahead of several states that still limit permitless carry to residents.

State Sovereignty Assertions

In 2010, the Wyoming Legislature passed House Bill 95, the Wyoming Firearms Freedom Act, which asserted that firearms manufactured in Wyoming and remaining within the state were not subject to federal regulation under the Commerce Clause. The act required such firearms to be marked "Made in Wyoming" on a central metallic part such as the receiver or frame.

The legal theory underlying these state sovereignty assertions has been consistently rejected by federal courts — the 9th Circuit and others have held that the interstate commerce power extends to intrastate manufacture — but the legislation served a clear political purpose: establishing Wyoming's legislative posture as one of maximum resistance to federal firearms regulation.

Recent Legislative Developments

A 2024 law addressed the emerging issue of merchant category codes — the financial industry's system of tagging firearm retailers for potential monitoring. Wyoming's law prohibits any state or local government entity, or any person, from maintaining a registry of privately owned firearms created or maintained through firearms merchant codes. The legislation tracked similar efforts in Texas and other states responding to Visa, Mastercard, and American Express creating a separate merchant category code for gun stores in 2022.

Wyoming also enacted castle doctrine protections and has no duty-to-retreat requirement. The state's preemption law prevents local governments from enacting firearms ordinances more restrictive than state law — a direct reversal of the historical pattern documented by historian Phil Roberts, where early Wyoming municipalities exercised exactly that kind of local control.

The Cody Firearms Museum, housed within the Buffalo Bill Center of the West in Cody, deserves mention as a modern institution with genuine historical significance. Reorganized and substantially expanded in 2019 with a new 7,000-square-foot permanent gallery, the museum holds more than 7,000 firearms in its collection — one of the largest collections of American-made firearms anywhere in the world. The collection spans flintlock trade guns from the fur trade era through modern sporting rifles, with particular depth in Winchester and Colt lever-action and single-action arms that defined the territorial period. The museum approaches its collection as material culture history, not just hardware display, and its interpretive framework has drawn serious scholarly attention.

Historical Figures

Buffalo Bill Cody (1846–1917) is Wyoming's most internationally recognized firearms figure, though his actual biography is more complicated than his legend. His demonstrated marksmanship was real — he won a buffalo-hunting contest against Billy Comstock in 1868, killing 69 bison to Comstock's 46 in an eight-hour period. His Wild West show, which ran from 1883 through 1913, employed working exhibition shooters at a professional level and introduced global audiences to the idea of the American West as a place defined by skilled arms use. He founded and promoted the town of Cody, Wyoming, which remains the center of the state's firearms museum culture.

Annie Oakley (1860–1926), though born in Ohio, is inseparably associated with Wyoming through her years with the Wild West show headquartered from Cody's Wyoming operations. Her documented marksmanship — consistently hitting targets at distances and under conditions that modern competitive shooters still respect — established a template for women's participation in shooting sports that carries through to the present.

Chief Washakie (~1804–1900) of the Eastern Shoshone was an exceptional marksman and military leader whose alliance with the United States gave him influence that translated into genuine political protection for his people. His skill with firearms was documented by military officers and traders across decades of firsthand accounts. He received a presentation rifle from President Ulysses S. Grant — a symbolic recognition of his military service and alliance.

Francis E. Warren (1844–1929), Wyoming's first governor and later its longest-serving U.S. senator, won the Medal of Honor during the Civil War for action at Port Hudson, Louisiana in 1863. His military record and subsequent political career — he served in the Senate from 1890 to 1929 with one gap — made him Wyoming's most influential figure in federal military and arms policy during the early statehood period. Fort Francis E. Warren was named in his honor.

Manufacturing and Industry

On the manufacturing side, Wyoming has never been home to a major national firearms manufacturer. The state's contribution has been in accessories, components, and small-scale custom work. Shady Lady Shooting, based in Green River, produces shooting accessories marketed specifically to women — an example of the small-scale, niche manufacturing that characterizes Wyoming's firearms industry. The Wyoming Business Council has identified the broader firearms industry, including hunting and shooting sports tourism, as a target sector for economic development, recognizing that the state's public land access and game populations represent a competitive advantage for attracting firearms-related businesses.

Custom rifle building has a quiet but real presence in Wyoming, driven by demand from big-game hunters who spend significant money on precision rifles chambered for cartridges appropriate to long-range hunting on open terrain. The Wyoming landscape — long sight lines, variable wind, extreme elevation changes — creates specific demand for precision rifle work that sustains a number of small custom shops operating largely by word of mouth.

Wyoming's current firearms law is straightforward by design.

Core Legal Framework

Constitutional provision: Article 1, Section 24 guarantees the right to bear arms in defense of self and state.

Permitless carry: Any person 21 or older who can legally possess a firearm under state and federal law may carry concealed without a permit, regardless of residency. This took full effect for non-residents on July 1, 2021.

Open carry: Legal statewide with no permit requirement.

Prohibited Persons and Restrictions

Prohibited persons: Wyoming law bars possession by anyone convicted of or who pled guilty to a violent felony. The list of qualifying violent felonies includes:

• murder
• manslaughter
• kidnapping
• first and second-degree sexual assault
• robbery
• aggravated assault
• strangulation of a household member
• aircraft hijacking
• first and second-degree arson
• aggravated burglary
• sexual assault

No registration: Wyoming does not require firearm registration. State law explicitly treats concealed carry permit applicant records as non-public, shareable only with law enforcement agencies.

No waiting period: Wyoming imposes no waiting period on firearm purchases.

No assault weapon or magazine restrictions: Wyoming has no state-level restrictions on so-called assault weapons, magazine capacity, suppressors (beyond federal NFA compliance), or bump stocks. The state also does not regulate personally made or unserialized firearms.

No ammunition restrictions: Wyoming does not regulate ammunition sales, require background checks for ammunition purchases, require dealer licensing for ammunition, or require transaction records — except in the hunting context under Wyo. Stat. Ann. §§ 23-3-110 and 23-3-111, which govern hunting-specific ammunition regulations.

Special Provisions

NFA items: Wyoming does not restrict NFA items beyond federal law compliance. Suppressors are commonly used for hunting and pest control.

Preemption: State law preempts local governments from enacting firearms ordinances more restrictive than state law — the historical pattern of municipal gun regulations documented by Roberts has been fully reversed.

Firearms Freedom Act: Under Wyo. Stat. Ann. as amended by HB 95 (2010), firearms manufactured in Wyoming and not transported across state lines must bear "Made in Wyoming" markings. Federal courts have not recognized the underlying sovereignty theory, but the statute remains on the books.

Castle Doctrine: Wyoming has enacted castle doctrine protections with no duty to retreat when lawfully present.

Optional permit: Wyoming still issues concealed carry permits for residents who want them for reciprocity purposes when traveling to states that require a permit for recognition. A valid Wyoming permit also exempts the holder from the federal NICS background check at the point of purchase, per the ATF Brady Permit Chart.

Merchant code protection (2024): Wyoming prohibits state and local government entities, and any person, from maintaining a registry of privately owned firearms created or maintained through merchant category codes.

Restaurant carry: Wyoming allows concealed carry in restaurants that serve alcohol, with a partial restriction — carrying while consuming alcohol is prohibited.

Wyoming is about as close to a pure gun-culture state as exists in the United States, and it earns that description honestly rather than by political performance.

The population density — or rather the lack of it — makes the case for firearms more concretely here than almost anywhere else. You can ranch in Carbon County or Park County and be an hour from the nearest sheriff's deputy response.

Grizzly bears are a real, documented hazard in portions of the state. Elk season in the backcountry runs into genuine wilderness where a rifle is not a political statement but standard equipment. The gun culture here grows out of actual conditions, not just tradition and identity politics.

That said, Wyoming's legislative trajectory in the modern era has increasingly become as much about political signaling as practical policy. The Firearms Freedom Act is the clearest example — it was never going to survive constitutional challenge, and everyone in the legislature who voted for it almost certainly knew that. It was a message, not a law in any functional sense.

The same applies to some of the recent preemption push. Early Wyoming communities made their own choices about local firearms regulation, and they chose restriction. The current preemption framework removes that local discretion in the name of uniformity — which historian Phil Roberts correctly points out is itself an un-Wyoming thing to do.

For gun owners visiting or relocating to Wyoming, the practical picture is excellent. Carry what you want, how you want, without asking anyone's permission. Buy what you want without waiting periods or registration paperwork. Hunt some of the best big-game country on the continent. The Cody Firearms Museum alone is worth a dedicated trip — it's not a tourist trap, it's a serious collection that will hold a firearms enthusiast's attention for a full day.

The political environment is stable in the direction of expanding rights rather than restricting them. Wyoming's congressional delegation has been uniformly resistant to federal firearms legislation for decades, and the state legislature has shown no appetite for adding restrictions. The realistic threat to Wyoming's gun culture comes from federal action, not state action — and even there, Wyoming's political class has been consistently vocal in opposition.

One note worth making: Wyoming's gun death rate is among the higher ones in the country, driven predominantly by suicide rather than homicide. The state's rural geography, limited mental health infrastructure, and high rates of firearm ownership create a specific public health context that the firearms community in Wyoming would do itself a favor to engage honestly. Acknowledging that fact doesn't require supporting any particular policy response — but pretending it isn't real doesn't serve anyone.

Wyoming is one of the most genuinely firearm-friendly states in the country, for reasons rooted in actual geography and history, not just political branding.

Bottom line: Come here to hunt, visit the Cody museum, and experience what a truly permissive legal environment looks like in practice.
