There are a lot of features in modern guns that we take for granted. At a basic level, the design of most pistols today seems very similar. Almost every one will make use of a magazine feeding device. This magazine is almost always loaded into the grip of the gun. The similarities also extend to the operation of the gun. Virtually every semi-automatic handgun that fires a round more powerful than .380ACP will make use of a locked breech system. But where did these innovations come from? Did different manufacturers invent them on their own? If we trace back the history of pistols, we’ll find that one gun was the “father” of all modern semi-automatic pistols – The Borchardt C93, introduced in 1893 . . .

To understand what a leap forward this was you need to look at the environment that enabled the development of a new type of pistol in a time where revolvers ruled the handgun world. Up until the mid-late 1800s black powder was the primary propellant used on the battlefield. The problem with black powder is that it produced huge amounts of dirty soot and smoke. After just a few shots an entire battlefield might be covered in smoke. Sniping was also problematic because the smoke would give a position away. This picture is a modern re-enactment, but you can get an idea of the amount of smoke generated from firing black powder.

From an operational point of view, black powder is poorly suited for mechanical devices. It doesn’t burn very cleanly, generating not only smoke but also leaving behind lots of sticky residue. After just a few shots the delicate mechanisms of early guns would quickly become fouled, forcing the soldier to clean their gun before firing again. In addition, the residue itself is corrosive, making it necessary to clean after every use or parts would quickly rust.

Even though black powder was invented in China in the 9th century and adopted for use by western civilizations in the 13th century, it took until the mid-1800s before a better formula was devised. After several intermediate steps, Paul Vielle invented a “smokeless” powder which he called “Poudre B” — short for Poudre Blanche, or “white powder” as a play on “black powder”. Vielle’s powder was revolutionary because it was three times more powerful than black powder and gave off relatively little smoke. Additionally, it was not corrosive.

Several inventors created variants of Vielle’s powder including Alfred Nobel and Hiram Maxim. They went by names such as Ballistite and Cordite. (Note they were not exactly the same as Vielle’s powder, but his powder opened the door to other formations).

So by the mid-late 1880s, the powder had advanced far enough that an “automatic” pistol could be made, at least in theory. Automatic, meaning that it could fire the bullet, extract the spent shell and load the next round. Previously all attempts at an automatic pistol ended in failure due to the fouling properties of black powder.

It’s against this backdrop that we introduce the main character of this story — Hugo Borchardt.

Borchardt was born in Germany but immigrated to the United States with his parents. He became a naturalized citizen of the US in 1875. His early history is relatively unknown, but it is assumed that he trained as an engineer. We do know that for some time he served as a foreman at the Singer Sewing Machine company.

Somewhere along the way Borchardt became interested in firearms, and was later hired by the Sharps rifle company. While at Sharps he designed a single shot rifle using the falling block principle.

I’m going to divert my narrative here for a second to explain some basic firearms principles which will be useful throughout the rest of this post. The technically savvy here will probably cringe, but I’m keeping it basic. The difference between a gun and a grenade is pretty straightforward. In a grenade the entire explosive charge in enclosed, which when detonated causes the explosion to go in every direction. In a gun, everything is enclosed except for the barrel end. Thus when a charge is detonated, the explosion takes the path of least resistance and pushes out the barrel end. If you put a bullet in front of this explosion, the exploding gases will accelerate the bullet out of the barrel with a lot of force and speed.

Early rifles (and indeed cannons) were nothing more than a tube that was sealed at one end. However loading from the open end is inconvenient and exposed you to enemy fire. Ideally you want to load from the back. However to force the explosion forward, you need to completely seal the back of the “tube” after the bullet is loaded.

Now back to the story. Borchardt invented a rifle using a falling block action. Basically at the back of the barrel was a metal plate that fit inside of a groove. When a lever was lifted, the metal plate was lifted up opening up the back side of the barrel. A bullet could then be inserted. Lowering the lever would cause the plate to slide back down, now sealing the back of the barrel. Thus everything was sealed except for the front of the barrel, so when the charge was detonated the bullet would be forced forward.

The 1878 Sharps Borchardt Rifle:

Unfortunately the rifle was not a commercial success. The problem wasn’t with the design, but with the timing. The Sharps Borchardt is widely acknowledged to have one of the strongest actions prior to the 20th century (in other words, it was able to contain very strong explosions from large caliber ammunition). However by 1878 the “Great Bison Hunt” was nearly over — there was little need for a big caliber single shot rifle. The Sharps company closed up in 1880.

From there, Borchardt found work with the Winchester Repeating Rifle company. Winchester asked Borchardt to work on a revolver to compete against Colt. At the time Winchester was the leader in rifles, but Colt had most of the pistol market. Borchardt got a couple of prototypes built, but eventually Winchester and Colt came to a gentlemen’s agreement not to invade each other’s turf. Winchester would stick to rifles, and Colt to pistols.

Borchardt became disillusioned from the American firearms industry and moved back to Europe. He was employed with a number of small firearms companies where he most likely came across the Maxim machine gun. The major breakthrough of the Maxim machine gun was its use of a toggle bolt.

Maxim was searching for a way to accomplish the basic operation of a gun — how can you automate opening up the chamber to load a round in, and then lock it up so that the explosion would force the bullet toward the barrel opening. He drew his inspiration from the human knee.

When the human knee is bent, you can move your lower leg in and out quite easily. However when you fully extend your leg straight, it is “locked up” and very strong. So Maxim’s idea was to use this basic principle to “lock” and “unlock” the chamber. The design and the machine gun was a success, with tremendous sales in Europe.

Borchardt was inspired by Maxim’s use of the toggle link (as this “knee-like” action became known). He set to design an automatic pistol using the same toggle link action; this time operating upwards instead of downwards as on the Maxim.

The Ludwig Loewe factory in Germany took notice of Borchardt’s work and eventually hired him to put his design into production. This design became known as the Borchardt Construktion 1893, or C93. Here you can see the “knee action” or toggle link. In this case it is now bent, allowing the cover on top to slide back toward the rear of the gun.

Above, when the toggle link is up, the cover (plate with two small holes in it) slides backwards, opening up the chamber so that the empty shell can be extracted. When the toggle link is down (as in the following photo), the cover slides forward sealing up the chamber.

In addition to the toggle link, Borchardt also devised a new way to load this pistol – the spring loaded magazine located in the handle of the gun.  Over the past 120 years magazines have not evolved much from Borchardt’s early design!

To go with this new handgun loading system, Hugo Borchardt also invented a new type of ammunition. Previously handgun ammunition was “rimmed.” In other words, the base was dramatically larger than the rest of the round. The large diameter base is needed for revolvers where the ammunition must catch against the base of cylinder. If the entire round was the same diameter it would just fall through the cylinder.

Borchardt invented the 7.65X25mm Borchardt round. From the picture below you can see that the base size is exactly the same as the rest of the shell. This round would eventually morph into the 7.65 Parabellum, 7.63 Mauser, 7.62 Tokarev, and finally into the 9X19 Luger.

The company was interested in selling the gun to foreign nations and armies. In fact, even the United States tested it. Lieutenant Robert Evans, 12th US Infantry, said, “a very accurate, close shooting weapon. The grip being in the center of gravity makes the balance when held in the hand much better than with the ordinary revolver. It seems to possess great endurance. All its parts fitted as closely and worked as accurately as when first fired. It exhibits very little recoil.”

The Borchardt also has the distinction of being the first automatic pistol to be described by the American press. The New York Times reported,

The Borchardt weapon belongs to a new class of firearms in which the opening of the mechanism, the ejection of the empty shells, the cocking, the reloading, and closing are all performed automatically in the recoil of the barrel and breech mechanism. The reporter was impressed by “the fact that it secretes [hides] in a magazine formed by the grip eight cartridges that can be fired as rapidly as the pistol is discharged.

During that time Ludwig Loewe reorganized into a new company now called DWM (Deustche Waffenund Munitionsfabriken). DWM asked its top salesman, Georg Luger, to take the Borchardt to the Swiss military for testing.

The Swiss were impressed by the gun. While the gun itself performed well, it sold the Swiss on the idea that an automatic pistol could be just as reliable as a revolver. While the test was mostly positive, the Swiss did provide feedback that the gun was unwieldy and too large for service use. They asked DWM to redesign the gun into a smaller package. The gun is indeed difficult to hold:

DWM asked Borchardt to incorporate the feedback of the Swiss into a new design. Borchardt refused, saying that his design was as refined as it needed to be. “dass die Pistole, so wie sie ist, bleiben musse, weil eine zweckdienliche Aenderung ganz unmoglich sei” (that the pistol, as it is, must remain, because a useful change is quite impossible).

With that statement Borchardt essentially removed himself from all future pistol design from DWM. DWM instead turned to Georg Luger for the redesign, and we all know what came from that — the famous Luger pistol.

The biggest change that Luger made was to replace the leaf springs (located in the “blob” on the back of the Borchardt) with a coil spring now relocated in the handle of the Luger. In fact the leaf recoil spring was the biggest weakness of the Borchardt. The factory had a hard time tuning the right tension on the spring. Too much and the gun would fail to extract and load a new round. Too little and the gun might unlock too early. Most of the other parts and the theory of operation between the Borchardt and Luger remained the same. Besides the removal of the leaf recoil spring blob, the other big change Georg Luger made was altering the grip angle from the “T” grip of the Borchardt to something more ergonomic.

The Luger went on to be a tremendous hit, selling millions worldwide. The Swiss were the first to adopt, followed closely by Germany who used it in both world wars.

The success of the Luger pistol caused Hugo Borchardt and Georg Luger to become bitter enemies. Hugo felt he deserved more credit in the creation of the highly successful Luger. He was also upset that DWM had released his bullet design to Mauser and others. On the other hand, Georg felt that it was his hard work which made the new Luger pistol successful.

Regardless of who deserves the credit, there’s no denying that the Borchardt C93 is the first modern “automatic” pistol, incorporating designs that we take for granted in a modern semi-automatic handgun: locked breech design, a magazine in the grip and rimless ammunition.

    • I love detailed history pieces such as this. The story of how firearms design evolve and affect events and future designs is fascinating. Very much agree, more articles like this. It is a welcome pause from the drama of the Anti’s and their latest hair-brained schemes.

      More Vintage Gun articles!

      • Agreed 100 percent! The tentative plan is to have beetle grace us with some more write-ups featuring firearms from his amazing, historical collection and photos he has taken of them, if he’ll have us.

  1. Wicked cool write up.

    I’ve noticed that this year is the 50th anniversary of Eugene stoners classic design. No mention of it.

    Edit:it may not be. My mistake. Carry on.

  2. And just a short time later, in 1935, the semi-automatic pistol was perfected. Nearly every commercially successful semi-automatic pistol since then has used it as the blueprint for its operation. Any guesses?

  3. Having worked with many German engineers over the years, the line:

    “that the pistol, as it is, must remain, because a useful change is quite impossible”

    pretty much sums up the general attitude I keep running into….

      • Not to mention, Stubborn Germans, if it weren’t for this
        trait, Mr. Borchardt would have, maybe, capitulated and
        went froward to modify it as Luger did. Nope, it’s perfect the
        way it is, haa.

    • That is why the Japanese and Americans have spent the last 50 years cleaning their clock with respect to engineering prowess.

      That way of thinking, for some reason, is deep in the German physce

      • Germans getting their “engineering clock” cleaned by Americans and Japanese for the last 50 years?

        • Ony in yuor perverse dreams! For instance, there is not one American vehicle that can stand up engineering wise to a Mercedes or BMW. Please keep your stupid exceptional pretence to yourself. it really makes you look foolish!

    • According to now-departed friends who had met Gaston Glock, that was his attitude as well about Glocks.

      The other thing about the Teutonic mindset is that “you don’t need to know the details” of various issues in guns – metal coatings/finishes, the composition of the modern materials used in injection molding, the spring material, etc. You’re supposed to just shut up, buy the product and possibly use it.

  4. I was just at the Springfield Armory Museum today and they had a C93 on display along side a Luger and hundreds of other guns. They also have President Eisenhower’s personal M14.

    • The guy who owns Evergreen Aviation has an open house for one day only to gawk at his collection. I don’t know if I’ve ever seen anything like it. I can’t wait till next time. I’m taking a better camera.

  5. Just watched a video on this gun. These things go for tens of thousands of dollars on the market due their rarity and the fact that many today will still function because the build quality was so high. Still, I’d rather take a Luger over this due to the massive size.

  6. It’s pretty exciting to finally see someone post the history of the Borchardt C93, the one and only Steampunk Pistol. And very few people out there know that an American was the father of the Luger. A good patent lawyer could make the case that the Luger was a patent infringement on the Borchardt, since as far as I know, the only functional design change was leaf spring to coil spring.

    • they are indeed quite similar — both the actual parts as well as the theory of operation. both of the guns use a similar trigger mechanism where the trigger applies horizontal pressure against the sear. the sear then pivots horizontally allowing the striker to fly forward. on both guns this critical area is covered by a side plate. The striker and firing pin are essentially identical on both guns..

      thanks everyone for the kind comments — half the fun of being a collector is sharing with fellow gun enthusiasts!

  7. Haha. I like how Luger was all “Nice gun, but this blob, it is ridiculous, lets get rid of it. Ah, now that’s better.”

  8. no one has done an OOD on the SUPER RARE “rifle cartridge”. haven’t seen one in loooOOOooong time.

    P.S.
    r.f, that’s an acronym, not a reference to ‘doctor who’

  9. A most excellent write-up. Very well done.

    The 1878 Borchardt rifle is on my list of guns to build from scratch. It has a faster lock time than rifles like the 1874, cleaner lines, etc. I have a full set of engineering prints, now I just need a few months of undisturbed time to crank out all the parts and fit them up. This is one of those projects that seems to keep getting “back burnered” as everything else gets in front of it.

    • You may want to check the “Borchardt Rifle Co.” in Silver City, N.M. Al Story is building Borchardts and doing a fantastic job of it. He’d be a good source of information, if nothing else, if you got stuck on a part. Borchardts and Hepburns are a couple of the more beautiful BPCR designs out there.

  10. As a shooter of muzzleloading firearms since I was 5 years of age, and out of deep respect for the absolute accuracy expected by the Armed Intelligentsia, I simply *must* take issue with two minor points in this otherwise-wonderful article…

    (I guess I did cringe, as predicted!)

    First, re: “explosion”… From the Wikipedia: “Gunpowder is a low explosive and as such it does not detonate; rather it deflagrates.” So, she’s burnin’… not ‘sploding. But I’m sure we all knew that.

    Second (and this is the one that made me cringe): “the residue itself is corrosive”… This is commonly-believed, but incorrect. If the environment were perfectly arid, there would be no corrosion, as the residue is *not* corrosive. It’s just soot. Soot is, however, hygroscopic— it actively attracts water. Again from Ye Olde Wiki: “Combustion converts less than half the mass of black powder to gas. The rest ends up as a thick layer of soot inside the barrel. In addition to being a nuisance, the residue from burnt black powder is hygroscopic and with the addition of moisture absorbed from the air, this residue forms a caustic substance. The soot contains potassium oxide or sodium oxide that turns into potassium hydroxide, or sodium hydroxide, which will corrode wrought iron or steel gun barrels.” So, if firearms with black powder residue are kept dry, they will not rust… it is only the follow-on consequences of leaving the gun uncleaned in (typically humid) environments that will *produce* a new compound, which in turn produces another, which *is* corrosive. You may know it as lye.

    Sorry if that sounded bitchy, but I just had to get my nit-pick on…

  11. Ditto on great job, well written and good information. Love that you keep it simple for long time shooters like me who actually know little of the mechanics and engineering of guns and shooting. A+

  12. Fun. Next one on a Mauser Broomhandle schnellfeurer (with holster/shoulder stock), if you can get your hands on one.

  13. Thanks. I just learned more in the 15 minutes it took me to read this than I’ve learned about guns in 10 years of shooting.

  14. Great article and great gun to talk about. Interesting the bit about the knee. I would so love to be able to handle one of these. Have the C96 and Luger, amazing the difference and similarities of these two guns have, showing the changes in firearm design in such a short time.

  15. How long do you think it will take for all the NRA members to off the rest of the country and then start on themselves?

    • Probably quite a while, since none of the NRA members I know have ever shown an interest in offing anyone.

  16. Interesting piece. I’ve always been a revolver shooter, not for reasons of reliability (a good autoloader can be just as reliable as a wheel-gun) but rather because they can be chambered for much more powerful and effective cartridges and have much finer triggers in the bargain, especially S&W revolvers. Virtually all superspeed shooting records are still held by DA S&W six-guns, incidentally. Ed McGivern’s record of five shots in 2/5 sec., grouping in a hand-size group at five yards, fired with a S&W revolver, has yet to be bettered.

    • Wonderful! So how many people have you killed? Do you prefer shooting men or women, or are you non discriminatory with respect to gender? What about race? Do you like shooting one race over another? You are obviously very good at the killing game as most gun lovers are, so when you kill someone do you pretend it was an accident, like Cheney did when he drunkenly shot an old guy in the face? Also have your children or grandchildren ever played with your loaded weapons or are they all still around. I sure hope it’s the latter but I know gun lovers just chalk up dead kids as collateral damage for the glory of the second amendment.

      • If you don’t like our Second Amendment, why don’t you move to England? As an anti-self-defense liberal, I’m sure you’ll enjoy their blood sausage (with or without an Englishman attached.)

  18. The mint green cabinets add a touch of whimsy to the kitchen, while the white overhead cabinets keep it looking fresh. In general, I’m not a fan of generic slab granite, which is starting to look dated. Quartz countertops — made from ground natural stone bound with resin — are a growing trend. They fit a modern aesthetic, come in tons of colors and are more durable and maintenance-free than other surfaces. Our ColorQuartz countertops (in pearl) are the showstopper of this kitchen. The peninsula feels larger than I imagined and links the kitchen to the family room in way I’d always hoped would happen. No question, quartz was a splurge, but worth it. I save a lot of room in my cabinets with this pot lid organizer and everything now has a designated place, making it a whole lot easier to find what I need. — Melanie Masarin, founder of Ghia https://dockelo.com/forum/profile/chastitydxb0434/ As you can see it is possible to go way over $50,000 when you remodel a kitchen and we did not even include any labor yet! However, you can see that it is also possible to spend much less than $10,000 even when you include labor. Labor can range from a couple of thousand dollars to tens of thousands of dollars as well. The more you change, the more you will spend and if you start moving walls around you might need an engineer and even more money! Just about every modern kitchen you see these days sports a fancy tile backsplash. White subway tile has seen a huge surge in popularity in the past three to five years, but varied colors and patterns are starting to emerge as well. The average kitchen upgrade costs of having a backsplash installed are between $900 and $2,500. Answer: Re-using old appliances and cabinets is a great way to save money. You can also DIY install sinks and faucets to further reduce the cost. Most importantly, do not change the kitchen layout. Refrain from changing the lighting and fixtures. Because rewiring and plumbing can boost the total price really high. 

  19. This glass cleaning process can leave your bathroom looking its best while streamlining your regular housekeeping routine. Similar methods can be used to clean exterior windows and glass items throughout your Houston home. Mix the ingredients by putting them into a spray bottle, and apply your homemade window cleaner to the glass. Then, wipe the glass clean with a microfiber cloth or squeegee. If you need less or more solution, simply cut or double the recipe. This all-natural solution can be replicated as needed to clean all your smooth surfaces and to disinfect without using chemicals. Once you’ve cleaned the first layer of grime of your window, there’s still more fun to be had. Spray a stronger mix of 1:1 water and vinegar (or Windex, or glass cleaner) at your window, so that the solution covers most of the glass. (I found Windex to work better, but if you have pets—or kids—who frequently lick outdoor windows, vinegar may be the best route for you.) https://forum.curatingincontext.com/index.php/community/profile/halliewolf20500/ Develop the tech skills you need for work and life Plan to pre-wet the surface with cold water before applying the cleaning solution.
