Search any UK gun rack for a used Browning over-and-under, and three names come up again and again: the B425, the Medalist and the B525. All three came out of the Miroku factory in Japan, all three share the Browning action that traces back to the B25, and all three are among the most sensible second-hand shotguns you can buy. They are not the same gun, though, and the prices asked for them vary more than the differences justify. This guide covers what separates the three, what the grade numbers mean, what to check before you buy, and which one fits the shooting you actually do.
The Browning–Miroku family tree in brief
The story starts with John Moses Browning’s B25 Superposed, still built by hand in Belgium at eye-watering prices. In the 1970s, Browning began sourcing a production version of the design from Miroku in Japan, and every gun in this guide descends from that decision. The Japanese guns keep the essentials: a full-width hinge pin, a deep underlug locking bolt, a single selective trigger, and automatic ejectors, while being machine-made to a price ordinary shooters can afford.
The B325 arrived in the late 1980s, the B425 replaced it in the mid-1990s, and the B525 took over in the early 2000s and remains the mainstream Browning over-and-under today, sitting below the B725 and the newer B825. The Medalist sits slightly to one side of that line: a Miroku-built Browning of the same era as the B325 and B425, sold in the UK as a plainer, keenly priced game and sporting gun. Because the bones are shared, a well-kept example of any of them will still be shooting long after its current owner has stopped.

Browning B425: The 1990s gun that refuses to date
The B425 is the one most UK searchers are looking for, and for good reason. It was made in large numbers through the second half of the 1990s in 12 and 20 bore, in game, sporting and trap configurations, and the actions have proved as durable as anything Miroku has built. Most 12-bore examples came with Browning’s Invector Plus multichokes and back-bored barrels; fixed-choke game guns exist and are often the lighter, sweeter-handling ones.
The grade system is where buyers get confused. Grade 1 is the standard gun: light scroll on the action, plain but decent walnut, and the same mechanism as everything above it. Grade 5 adds game-scene engraving and noticeably better wood; Grade 6 goes further again with deeper, hand-finished engraving and figured stocks. Mechanically, they are identical, so a Grade 1 is not a lesser shooting gun; you are paying for decoration and timber. The Waterfowl variant is the odd one out: a long-chambered 12 bore built for heavy steel loads, worth seeking out if you shoot foreshore, and worth avoiding if you want a light game gun.
On the used market, the B425 tends to sit at the value end of the Browning range simply because of its age. That is the opportunity. A tight Grade 1 with honest barrels is one of the best pound-for-pound over-and-unders in the country, and a Grade 5 or 6 gives you a genuinely handsome gun for less than a plain new one.

Browning Medalist: The affordable one people overlook
The Medalist has never had the profile of the numbered models, which keeps its prices friendly. It was sold in the UK mainly through the 1990s as a straightforward 12 or 20 bore over-and-under with a plain action, modest wood, and either fixed or multichoke barrels depending on the example. Think of it as a B325/B425-era gun with the decoration budget spent on nothing at all.
That plainness is exactly why it suits certain buyers. If you want a Browning-quality action for rough shooting, pigeons, a first season of driven days, or a club clay gun that will get knocked about, a Medalist does the job without the worry that comes with a pretty gun. Handling is typically a touch heavier than a fixed-choke B425 game gun, which is no bad thing on clays.
Refinished stocks and chequering are common on Medalists because they were used hard; that is cosmetic, not a fault. The mechanical checks are the same as for any Miroku-built Browning, covered below.

Browning B525: The modern default
The B525 replaced the B425 in the early 2000s and is still in the catalogue, which means the used market is deep and the range of specifications is wide. The fundamentals are the same Miroku action, but the B525 brought a lighter, slimmer feel to the game guns, improved wood-to-metal fit across the grades, and a more coherent model line-up: Game One and Sporter One at the entry point, Hunter and Liberty Light as lighter game guns, then the higher-grade Game and Sporter models with finer engraving and better walnut.
Because there are so many B525s about, the price spread is large. An early Sporter One that has fired a lot of cartridges can be very reasonable; a recent higher-grade Game with a 30-inch barrel and little use will not be far off a new gun. The buying advice is to judge each gun on condition and specification rather than on the model name; a B525 is a B525, but a 2004 Sporter One and a 2022 Grade 5 Game are very different propositions.
If you want the newest features, a mechanical trigger, the latest chokes and forcing cones, the lowest-profile action, that is the B725 or B825, not the B525. The B525’s appeal is that it is the proven, mid-priced Browning with the widest choice on the used racks.

Side by side: How the three compare
Action and reliability: identical in kind. All three lock with a full-width underlug bolt on a full-width hinge pin, all have single selective triggers and ejectors, and all will take decades of use. A B525 feels slightly slimmer and lighter in its game forms; a B425 or Medalist a fraction more solid.
Barrels and chokes: most 12-bore B425s and all B525s have multichokes; the Medalist and fixed-choke B425 game guns are the exception, and fixed chokes are no drawback for driven game.
Grades and price: the B425 Grade 1/5/6 ladder and the B525’s Game One to higher-grade line-up map onto each other reasonably well; the Medalist is simply the plain gun. Used, the Medalist is generally the least expensive, the B425 sits in the middle, and the B525 covers the widest range. For a given sum, you will usually get a higher grade of B425 than B525.
Best for: driven game, a fixed-choke B425 Grade 5 or a B525 Hunter/Liberty Light; sporting clays, a B525 Sporter or 30-inch B425 Sporter; rough shooting, pigeons and a first gun, Medalist or B425 Grade 1; foreshore with steel, B425 Waterfowl or a later B525 proofed for steel.

What to check before you buy any used Browning
Start with the top lever: on a Browning it should sit to the right of centre with the gun closed. As the locking bolt wears, it drifts towards the middle, and a lever at or past centre means re-jointing sooner rather than later. Check the gun is on the face with the forend removed; any daylight between barrels and action is a gunsmith’s job.
Look down the bores for pitting and along the outside for dents and lifted ribs. Ask about the chokes, since seized multichoke tubes are a nuisance to discover afterwards. Fire the ejectors with snap caps and make sure both throw together. Finally, check the stock for cracks behind the action and through the wrist, and for oil-soaked, blackened wood at the head. Brownings get shot a lot, so the ones on the market range from nearly new to thoroughly tired: buy on condition, not on grade or year.

FAQ
Is the Browning B425 a good gun? Yes. Built by Miroku in the mid-to-late 1990s on the action that underpins every modern Browning over-and-under, well-kept examples are reliable, well-balanced, and good value.
What is the difference between Browning B425 Grade 1 and Grade 5? Mechanically nothing. Grade 1 has light scroll engraving and plainer walnut; Grade 5 has game-scene engraving and higher-figure wood; Grade 6 goes further again. The gun underneath is the same.
Is the Browning Medalist the same as a B425? Not exactly. The Medalist is a Miroku-built Browning of the same era sold as a plainer, lower-priced model: same action design, less decoration, simpler wood and, on many examples, fixed chokes.
Is a B525 better than a B425? Newer rather than better. The B525 is slimmer in its game forms and still in production, so choice is plentiful. A good B425 shoots just as well, and second-hand you will usually get more grade for your money with the older gun.
