If you like the .357 Mag, the S&W Registered Magnum is as close to a holy grail as it gets. This gun debuted that cartridge and did so with a hell of a bang.

You have to go back to the 1930s to appreciate the legend. The .38 Super Automatic still ruled then, being the only US pistol cartridge that could penetrate car doors or body armor.

The Smith and Wesson Registered Magnum changed that. Clocking over 1,500 FPS from an 8.75” barrel, it outdid the .38 Super by nearly 30%! It was a monster nobody had seen before.

So if you want to sell a Registered Magnum today, you’re in for a treat. These guns made history and as such, sell for great prices. Today, we’ll show you how to value one.

PS: If you're checking its value to sell your gun, ensure you follow federal rules. Read our guide on how to sell a gun online to stay 100% legal.

How We Calculate Used Registered Magnum Values

The value of an S&W Registered Magnum is affected by its condition, the rarity of its configuration, its accessories, and its historical significance.

Condition and Value

S&W Registered Magnum

Revolvers in good shape sell for more. By “in good shape,” also check if your 357 Registered Magnum still has its original or period-correct parts.

A recently refinished Registered Magnum may look good, for instance. However, its condition drops because the modern refinishing isn’t original or authentic to the time period.

To see how we professionally evaluate your firearm (for free) and turn that condition into a payout, view our 3-step selling process for a guaranteed FFL offer.

At any rate, you can use these condition tiers to grade your gun:

New or Mint

Bought from the company but never fired. It should be perfect in every way, from finish to function. S&W 357 Magnum price history gives these the best values.

Excellent

Hardly ever used and it shows, with near-perfect looks. Sell for just 10% or so less than mint-condition guns.

Very Good

Used on the sparing side, with only mild wear and handling marks. Sell for just 20% or so less than mint-condition guns.

Good

Well-used but also well-maintained. It still works perfectly and has controlled wear on its appearance. Sell for about 30% or so less than mint condition.

Fair

Well-used but not well-maintained. Sell for about 40% less than mint condition.

Poor

Very worn, with clear defects, or possibly no longer functional. Sell for around 50% less than mint condition, depending on how bad it is.

The Impact of Configuration Rarity

S&W Registered Magnum

To explain this, let’s ask “What is a Registered Magnum?” first.

The answer: this S&W revolver is a custom-order sixgun chambered for the .357 Magnum.

Buyers placed custom orders for specific parts to be hand-assembled and hand-fitted for it. Each gun initially took 3 to 4 weeks to finish, with demand spiking it to 6 weeks later on.

People could choose from a range of options for different parts. Some options were more popular than others, like the blued finish being more requested than the nickel.

That’s why there are Registered Magnums today that have rare configurations. It means they’re worth more because only a few of them exist today. Here are the rare parts worth noting:

Rare Registered Magnum Barrels

The rarest barrel lengths for the Registered Magnum are 5.75, 6.25, 7.25, and 7.75 inches.

The most common barrel lengths, by comparison, are 6.5, 5, 6, 8.75, 4, and 3.5 inches. That’s in descending order, so the 6.5-inch ones are most common.

Value: Guns with uncommon barrels add 10% to 30% over the standard price. Those with the 4 rarest barrels we listed earlier add up to 50% more.

Rare Registered Magnum Grips

The rarest S&W 357 Registered Magnum grip options are pearl, ivory, stag, roper, and tuskoid. The last one is so rare that only one ever shipped out of the factory.

The most common grips for the gun, by comparison, are the standard (pre-war service style) and Magna grips in walnut.

The price increase for the rare grip options is dependent on whether or not you can prove the grips are original. You can do this by getting a factory letter. You’ll learn how later!

Value: For rare and period-correct but not factory-installed grips, add about 10% to the price. For factory-installed rare grips, add about 20% to 50% to the price.

Rarest Registered Magnum Finish

The rarest Registered Magnum finish is the nickel one. Some suggest under 200 were made.

The blued version was more popular among buyers. The nickel version also cost more to order back then.

This is a model that holds value well. Because it’s a premium firearm in the line, we use a secure gun shipping and buying system to ensure every transaction is fully insured and legally compliant.

Value: Add about 50% to the standard price for a nickel gun.

How Accessories Affect What We Pay for Your Magnum

Registered Magnum certificate

For the Smith and Wesson Registered Magnum, several accessories can improve pricing. Here are the important ones:

Original Box

Registered Magnums originally shipped with a blue cardboard box. They’re valuable enough to sell alone or with a gun.

Value: $800 and up

Certificate of Registration

The Registered Magnum gets its name from this certificate. The guns were shipped with a card that the owner could fill out and send back to Smith & Wesson.

Smith & Wesson would then mail back a registration certificate for the gun. It had these details:

  • The owner’s name
  • The gun’s barrel length
  • The gun’s trigger pull in both single- and double-action
  • The yardage at which the gun was sighted
  • The gun’s registration number (matched to the one stamped on the gun’s yoke)
  • The signature of S&W’s vice-president at the time, Doug Wesson

Less than 50% of Registered Magnum owners requested these certificates from Smith & Wesson! So, the guns with certificates are very valuable.

You can technically sell the registration certificate by itself too. However, it can sell for more with the matching gun.

Value: $800 and up by itself, $1,600 and up with the matching gun

Postmarked Mailing Tube

When Registered Magnums’ certificates of registration were sent to owners, they came in a postmarked mailing tube. These tubes are also valuable enough to sell on their own.

Value: $300 and up

Letter of Authentication

Letters of authentication can help you trace the history of your gun. They also confirm its original parts or factory configuration, which can boost value if it’s still as it was shipped.

Smith & Wesson used to offer this service themselves through their in-house historian Roy G. Jinks. Jinks has since moved to the Smith & Wesson Historical Foundation.

Contact them through their website to get a letter of authentication request for your gun. It costs about $90 now and you can add that cost to your gun’s sale price if it pans out.

Value: About $90

The Impact of the Gun's Historical Significance

__wf_reserved_inherit

Registered Magnums that have something historically special about them will sell for more.

The best example is probably the gun with Reg. No. 2. This was a Smith and Wesson Registered Magnum worth buying for two huge reasons:

  • It was the second Registered Magnum ever made.
  • It was owned by Phillip Sharpe, who helped design the .357 Magnum cartridge.

As you may expect, it sold for a lot – $54,000 at an auction in 2019. Given Registered Magnum 357 history price-wise, it would sell for even more now.

Value: Highly variable, so it’s recommended to get a professional appraisal

Resources for Appraising a S&W Registered Magnum

Think you need more tools to find the right price for a Registered Magnum? You can use these to get an informed or professional appraisal:

A Note on Registered 357 Magnum Price History

Registered Magnum box

The Registered Magnum originally sold for $60. That’s around $1,413 in 2024, so you can tell the gun was always a high-end one. Comparison to other 1930s guns proves it too!

The Smith & Wesson K-Frame Revolver could be bought for only $22 then, for example. Meanwhile, high-end shotguns like the Winchester Model 21 cost the same as the Magnum.

$60 was two weeks’ worth of pay for the average person then. It’s even more impressive when you consider orders for the gun were backed up during the Great Depression!

Over the years, the gun’s rarity and history have sent its pricing up. Take one sold for $12,000 in 2019 by auctioneers Lock, Stock, & Barrel. Estimates now say it could sell for about $18,000 today.

This means the Registered Magnum may be one of the most collectible, investment-grade firearms. As such, it can be worthwhile to get an expert appraisal like ours to sell yours. This will stop you selling it for less than it’s worth!

General Questions & Answers

The first .357 Magnum gun is the Registered Magnum from 1935. Some sources will say it’s the Smith & Wesson Model 27 but that’s incorrect, as the Registered Magnum preceded it.

The Registered Magnum gets its name from the certificate of registration that shipped with it. It’s worth noting that it was originally called the .357 S&W Magnum, though. Smith & Wesson didn’t use model numbers for guns until 1957, so earlier models were named descriptively.

The Registered Magnum was made by Smith & Wesson from 1935 to 1939. The company replaced it with the production-line S&W Model 27 after October 16, 1939.

Estimates for how many Smith and Wesson Registered Magnums were produced vary, but most gun historians estimate 5,200 to 5,500 produced in total.

Smith and Wesson Registered Magnum serial numbers often run from 45768 to 62489.

You can find 357 Magnum serial numbers on the butt of the gun, as with most other S&W models.

No, the registration numbers of Registered Magnums are different from their serial numbers. The registration numbers start with “REG” and are stamped on the gun’s yoke. Serial numbers are stamped on the gun’s butt.

These famous people owned 357 Registered Magnums: J. Edgar Hoover (S&W gave him the gun with Registration no. 1), General George Patton, Colonel Rex Applegate, Jimmy Stewart, Phillip Sharpe, Gary Cooper, Ed McGivern, Elmer Keith, Clark Gable, and Jelly Bryce.

The S&W Registered Magnum is special because it was the first .357 Magnum gun and was produced as a customizable, hand-fitted firearm that outclassed other revolvers in quality. It was arguably the most powerful revolver of its time. Because only 5,200 to 5,500 were produced, it also has rarity boosting its value today.
