In the rarefied world of London best-gun making, Boss & Co occupies a singular position: the gunmaker that invented the modern over-and-under shotgun. While Purdey and Holland & Holland built their reputations on exquisite side-by-side doubles, Boss fundamentally reimagined what a shotgun could be — and in doing so, changed the trajectory of shotgun design for the entire industry. Founded in 1812, Boss & Co has survived for over two centuries on a simple formula: build fewer guns than any competitor, build them better than any competitor, and let the quality speak for itself. Today, with an annual production measured in single digits and a waiting list that can stretch beyond a decade, Boss represents the most exclusive tier of bespoke gunmaking — a world where a single sidelock over-and-under can command prices exceeding £150,000 and is considered, by those who know, to be the finest repeating shotgun ever produced by human hands.
The Founder: Thomas Boss (1790–1857)
Thomas Boss was born in 1790, the son of a London clockmaker. The precision of clockmaking — the microscopic tolerances, the intricate mechanical relationships, the demand for absolute reliability — would prove to be the perfect foundation for a gunmaker. When Boss entered the gun trade, he brought with him a clockmaker's obsession with fit and finish, a sensibility that would define his company for the next two centuries.
Boss established his first shop in 1812 at 222 High Street, St. Giles, in central London. The timing was significant: Britain was at war with Napoleonic France, and the demand for military arms was enormous. But Boss chose a different path — he would build only sporting guns for gentlemen, refusing to compromise his standards for military volume. This decision limited his immediate income but established his reputation as a maker who valued quality above all else.
By the 1830s, Boss had earned a reputation for guns of exceptional handling and reliability. His shop attracted a loyal clientele of sportsmen who appreciated the clockmaker's precision evident in every lock, every trigger, every fitted joint. Though Boss never achieved the scale or royal patronage of contemporaries like Purdey, his name became synonymous with the highest tier of craftsmanship — a niche he was happy to occupy.
The Early Years (1812–1857)
Like most London gunmakers of the era, Boss initially built flintlock fowling pieces, transitioning to percussion ignition in the late 1820s as the technology matured. His guns were noted for their particularly fine lockwork — a direct inheritance from his clockmaking background. The Boss flintlock locks were renowned for their speed and reliability, with sear engagements so precisely cut that the trigger pull was consistently crisp and light.
Thomas Boss was a modest man who avoided the self-promotion that characterized some of his competitors. He did not seek royal warrants or public attention; he simply built the best guns he could and let his clients do the talking. This ethos — quiet excellence, no marketing, no compromise — became embedded in Boss & Co's DNA and persists to the present day. Boss has never had a Royal Warrant, a fact that the company wears as a badge of honor: they do not need a royal seal when every gun is already a royal gun.
Upon Thomas Boss's death in 1857, the firm passed to his widow and then to a series of owners who maintained the quality standards. The company relocated several times — to 73 St James's Street in the 1860s, then to 13 Dover Street in the 1890s, each move reflecting the business's evolution and the changing geography of London's luxury trade.
Key Historical Milestones
1891 – The Robertson Patent Over-and-Under: In a moment that would redefine shotgun design, Boss & Co began building guns on the Robertson patent over-and-under action. John Robertson was a Scottish gunmaker who had developed a stacked-barrel design with a low-profile action — a gun that offered the single sighting plane of a single-barrel while retaining the two-shot capability of a double. The design was mechanically elegant but had not found commercial success. Boss recognized its potential and acquired the rights to refine and produce it.
1909 – The Boss Over-and-Under: After nearly two decades of refinement, Boss & Co introduced what would become its defining product: the Boss Over-and-Under. The Boss O/U featured the Robertson-style low-action design, but with Boss's clockmaker-grade lockwork and a self-opening mechanism that made reloading lightning-fast. The gun's most distinctive feature was the Boss single trigger — a mechanical trigger that fired the bottom barrel first, then the top, without the shooter needing to change grip or consciously select a barrel. The single trigger was reliable, crisp, and became a Boss signature.
1927 – Acquired by the Shooting Stars: Boss & Co was acquired by John Robertson (no relation to the patent holder) and Bob Henderson, two of the most celebrated competitive shooters of the era. Robertson and Henderson brought a shooter's perspective to gunmaking: they understood exactly what a competition gun needed, and they pushed Boss's standards even higher. Under their stewardship, Boss guns became the preferred choice of serious game shooters and competitors who demanded the very best.
1939 – The Boss & Co Sidelock: Boss perfected its sidelock action, a mechanism where the lock plates are mounted on the outside of the action body rather than inside (as in a boxlock). The sidelock configuration allows for larger, more robust lock components and provides a canvas for the engraver's art. Boss sidelocks are considered among the finest ever made, with hand-detachable locks that can be removed without tools for cleaning and inspection — a feature that requires extraordinary precision to execute correctly.
Iconic Firearms
The Boss Over-and-Under Shotgun
The Boss Over-and-Under is the company's defining creation — arguably the finest repeating shotgun in the world. Built on the Robertson-style low action, the Boss O/U is immediately recognizable by its shallow action profile and distinctive rounded action body. The gun's handling characteristics are legendary: despite having two barrels, it points and swings like a single-barrel trap gun, with a moment of inertia precisely calculated to match the individual shooter's swing. The Boss single selective trigger is a mechanical masterpiece — a non-inertia trigger that cycles reliably regardless of recoil, firing the bottom barrel first (for lower perceived recoil) then the top. Each Boss O/U is regulated to shoot both barrels to the identical point of impact at 40 yards — a standard that few other makers even attempt. Production is extraordinarily limited: typically 4–6 guns per year, with each taking 18–24 months to complete.
The Boss Side-by-Side Shotgun
While the over-and-under is the Boss signature, the Boss side-by-side is no less accomplished. Built on the Boss sidelock action with the company's characteristic single trigger and self-opening mechanism, the side-by-side combines traditional aesthetics with modern mechanical precision. The Boss side-by-side weighs between 6¼ and 6½ pounds in 12-bore — light enough for all-day carrying, heavy enough to swing smoothly — with stock dimensions cut to the individual customer's physique and shooting style.
The Boss Double Rifle
Boss also built double rifles, though in far smaller numbers than its shotguns. A Boss double rifle in calibers like .470 Nitro Express or .500 Nitro Express represents the absolute summit of the dangerous-game rifle. The same obsession with fit and regulation that characterizes Boss shotguns is applied to the double rifles: barrels are regulated with fanatical precision, actions are scaled and balanced for their specific caliber, and stocks are shaped to manage the ferocious recoil of the big nitro cartridges while maintaining instinctive pointing characteristics.
| Model | Type | Key Feature | Era |
|---|---|---|---|
| Over-and-Under Shotgun | Break-action O/U | Robertson low action, Boss single trigger | 1909–present |
| Side-by-Side Shotgun | Break-action double | Sidelock, hand-detachable locks, self-opening | 1812–present |
| Double Rifle | Break-action double | Hand-regulated, big-game calibers | 1860s–1920s |
Boss Craftsmanship and Bespoke Process
What sets Boss & Co apart from even its most prestigious competitors is the depth of personalization available to each client. When a customer commissions a Boss shotgun, the process begins not with a catalog of options but with a conversation: what kind of shooting do you do, where do you shoot, what is your build, your dominant eye, your preferred balance point? A Boss gun is not built to a specification — it is built to the individual. The fitting process alone can span multiple sessions, with the client shouldering a try-gun that the stocker adjusts incrementally until the point of aim is instinctive and the recoil impulse travels straight back into the shoulder rather than up into the cheek.
Every Boss barrel set is struck from solid steel forgings and regulated through a process of repeated test-firing and hand-adjustment. The barrels must print both patterns to precisely the same point of aim at 40 yards — a standard that demands extraordinary patience from the barrel maker and can add weeks to the production of a single gun. The Boss single trigger, widely considered the finest selective single trigger ever made, is a purely mechanical design: no inertia blocks, no recoil-dependent resets. It fires the bottom barrel first (to minimize muzzle rise), then the top, and it resets positively regardless of the cartridge load. The mechanism is so reliable that Boss will warrant it for the life of the gun without qualification.
Engraving on a Boss gun is executed by one of a handful of master engravers who work almost exclusively for the firm. The standard pattern is fine English scroll with the makers name in flowing script, but clients have commissioned everything from game scenes depicting their favorite shooting grounds to family crests and personal emblems. The level of detail is such that a single action body can absorb over 100 hours of engraving time before the gun ever reaches the stockers bench.
Notable Boss Clients and Guns
Boss & Cos client list reads like a who is who of 20th-century wealth and influence. King George V was a Boss shooter, and while the company never sought a Royal Warrant, the Kings personal patronage was endorsement enough. The Maharaja of Bikaner commissioned a pair of Boss O/Us in the 1920s, finished with gold inlay and presented in a leather case lined with silk. American industrialists — names like DuPont, Vanderbilt, and Ford — crossed the Atlantic to be measured for their Boss guns at Dover Street. The novelist Ernest Hemingway admired Boss guns and mentioned them in his writings on shooting. In the modern era, Boss shotguns have been commissioned by technology entrepreneurs, hedge fund managers, and Middle Eastern royalty — clients for whom a five-year wait and a six-figure price tag are merely the entry requirements to the most exclusive club in firearms.
A particularly notable Boss gun is the Golden Boss — a display-grade O/U completed in the 1990s with gold-inlaid engraving depicting scenes from driven pheasant shooting, exhibition-grade Turkish walnut with feather crotch figure extending the full length of the stock, and gold-plated internal lock components visible through the hand-detachable lock plates. The Golden Boss was featured in several books on fine gunmaking and has been valued at well over £200,000 — a price that reflects not just the materials and labor but the decades of accumulated skill represented in every fitted surface.
Legacy and Modern Era
The late 20th century was brutal to London's gunmakers, and Boss was not immune. The firm changed hands several times, at one point becoming part of the same corporate group as Purdey. But unlike many heritage gunmakers that were reduced to importers or brand-management operations, Boss & Co maintained an active workshop and continued to build guns — albeit in microscopic quantities.
Today, Boss & Co operates from 13 Dover Street in Mayfair, the same premises it has occupied since the 1890s. The workshop employs fewer than 10 craftsmen, each a master of their discipline: actioners who fit the locks to tolerances measured in thousandths of an inch; stockers who spend months shaping a single piece of walnut; engravers who transform steel into delicate filigree. The annual production — typically 3–6 guns — makes Boss the most exclusive of London's surviving best-gun makers. The waiting list is indefinite; new orders are accepted only when a slot opens in the production schedule, and a client who commissions a Boss O/U today may wait 5–10 years for delivery.
Boss & Co has never sought publicity or expanded beyond its natural scale. There are no Boss-branded clothing lines, no shooting grounds, no marketing campaigns. The company exists for one purpose: to build the finest shotguns in the world. The market has validated this approach — a pre-owned Boss O/U from the 1920s in good condition can sell at auction for £50,000–£80,000, while a recent-production Boss commands over £150,000 and appreciates immediately upon delivery.
Perhaps the ultimate testament to Boss's standing came from Geoffrey Boothroyd, the firearms authority who famously advised Ian Fleming on James Bond's choice of sidearm. Boothroyd called the Boss over-and-under "unquestionably the finest shotgun in the world" — an assessment shared by generations of gunmakers, shooters, and collectors who have handled one.
MatchMyGun Verdict
Boss & Co represents the purest expression of the London gunmaking tradition: no marketing, no brand extensions, no compromise. The Boss Over-and-Under — the gun that single-handedly legitimized the stacked-barrel shotgun in the eyes of the British shooting establishment — remains the standard by which all other O/Us are judged, including those from makers many times Boss's size. That a company with a workforce smaller than a football team and an annual output that can be counted on one hand has exerted such an outsized influence on firearms design is a testament to the power of uncompromising craftsmanship.
The Boss story is one of focus. While other gunmakers diversified into clothing, shooting grounds, and brand licensing, Boss simply continued to build guns — fewer of them, slower, better. In an era of automation and mass production, Boss & Co stands as proof that the old ways — the clockmaker's precision, the individual craftsman's skill, the refusal to accept "good enough" — can still produce something that machines cannot replicate: a work of functional art that will be prized for centuries.
