The birth of the Bren Ten is directly linked to the birth of the 10mm. Without one, we wouldn’t have the other, which is great because I love the 10mm.
The Bren Ten had a lot going for it and had tons of hype, but then it crashed and burned.
Today we are going to explore what happened to the Bren Ten.

The Mighty Bren Ten
The year is 1983. Hair is big, pants are high, and the music is synth-heavy.
In the firearms world, particularly the police world, it’s either .38 Special, .45 ACP, or 9mm. But apparently, those weren’t good enough.
The 10mm and the Bren Ten came to be because of a convergence of famed instructor Jeff Cooper, firearms company Norma, and a company called Dornaus and Dixon Enterprises.
Between these three, the development of the 10mm and Bren Ten began in 1983.
Its name is a throwback to the famed Bren light machine gun. But you might be asking, “Why would a 10mm pistol be named after a .303 Enfield light machine gun?”
The Bren gun, specifically the ZB vz. 26, was manufactured in the Czech city of BRNO. The BR from Brno combined with the EN from Enfield to make the Bren.
A Czech-based name was chosen because the gun was largely based on the famed CZ 75. Sprinkle in the fairly obvious Ten to designate 10mm, and we get the Bren Ten.
In Dornaus and Dixon’s own words, they intended the Bren Ten to be the successor to the Colt M1911. With the legendary Jeff Cooper backing them, it seemed possible.
This is from the Dornaus and Dixon 1984 catalog:
Dornaus & Dixon Enterprises was formed in December 1979 with the combined efforts of two men, Thomas F. Dornaus and Michael W. Dixon, who had decided to build what they hoped would be the heir to the Colt .45 Auto.
In January 1980, they went seeking advice from the most knowledgeable sources available. This effort naturally led to Jeff Cooper. Upon seeking his advice, it was discovered that Jeff Cooper, likewise, was working on such an arm.
It was decided that Dornaus & Dixon and Jeff Cooper would join forces, with Jeff Cooper providing conceptual design criteria, as well as technical advice based on his vast practical experience, and Dornaus & Dixon providing the engineering, development, manufacturing, and marketing expertise.
To retain his professional objectiveness, Jeff Cooper is not an employee of Dornaus & Dixon Enterprises, nor does he have any authority in the manufacturing of the Bren Ten.
Into the Bren Ten
The Bren Ten used the basic CZ layout but with a fair bit of modifications.
It utilized a double-action, single-action design with a frame-mounted safety and had a standard capacity of ten rounds of 10mm in a box magazine.
Ten-round magazines were the production mags, but it’s worth mentioning that in the 1981 issue of Soldier of Fortune, Ken Hackathorn said his prototype held 12 rounds of 10mm.
The magazine could drop freely or pop out halfway depending on how the user sets the “selective magazine catch.” Drop-free magazines meant a faster reload, but retaining magazines was easier when set to only pop out halfway.
It also sported a CZ-style manual safety that allowed for locked and cocked carry, as well as a cross-bolt safety that locked everything up.
The safety could be swapped for lefty use. According to Cooper, it had also been trimmed, melted, and dehorned for a smoother draw.
Another feature called Power Seal rifling supposedly offered more velocity and higher accuracy. The weapon also had an adjustable rear sight and a lanyard loop.
A standard model Bren Ten weighed 38 ounces with a 5-inch barrel and an overall length of 8.75 inches. The Bren Ten could also fire .45 ACP with a slide and barrel change.
Numerous models were built, including standard, compact, pocket, target, and competition models. There was also a Special Forces model that featured a black slide.
Various other limited editions were produced, including a run of 2000 Jeff Cooper limited edition guns that were supposedly all inspected by Cooper himself.
At the time, the CZ 75 was basically high-tech and offered a very ergonomic and robust platform, and a beefed-up 10mm CZ-style pistol seemed promising.
The Hype Machine Starts
Gun magazine after gun magazine touted the Bren Ten as the handgun of the future.
In an April 1981 magazine, Ken Hackathorn called the trigger one of the smoothest he’d ever experienced. Cooper said the same in a 1982 issue of Gun Digest.
The hype was already palpable, and then a little show called Miami Vice premiered. Michael Mann, who is a bit of a gun nut himself, directed the series.
He wanted the latest and greatest gun, which meant the star character Sonny Crockett, played by Don Johnson, would go on to carry the Bren Ten.
Crockett wielded the Bren Ten for two seasons. The production used two guns built personally by Tom Dornaus. Funny enough, they were .45 ACP variants because 10mm blanks didn’t quite exist yet.
Miami Vice was a massive success. Bren Tens flew off the shelves, and preorders exploded, but the gun wasn’t ready for stardom.
Unfortunately, Dornaus and Dixon were met with immediate supply issues.
The magazines were contracted to an Italian firm, but the Italian government halted shipment of the mags, declaring them war materials.
So what was Dornaus and Dixon’s solution? Shipping guns without magazines and promising delivery at a later date.
Weapons were being made so quickly that quality control couldn’t keep up. Soon the guns began suffering issues.
On top of that, the 10mm of the time was being loaded extremely hot, further exasperating durability issues.
This resulted in frames cracking, slides breaking, and more. Poor parts fitment resulted in unreliable guns. When a substandard product crops up amidst long wait times, people pull their money. That’s exactly what happened to Dornaus and Dixon.
Between canceled preorders, refunds, and a lack of magazines, the company went bankrupt — and Bren ten sank with that ship.
A few companies tried to revive Bren Ten, but public interest had waned; people had already been burned. Bren Tens are now collector’s items with a strong cult following.
Would the Bren ten succeed today?
EAA has had 10mm options for its Witness (CZ 75-based) line for decades. CZ Custom also previously offered 10mm conversions for the CZ 97BD. Clearly, there is at least some market for 10mm CZ-style guns.
