The Bren 10 is one of those pistols that burned bright and fast. It had a short production run, a big idea, and a legacy that still sparks debates at the range. Most people met it through Miami Vice, where Sonny Crockett carried a two-tone Bren Ten in a shoulder rig. Off-screen, the pistol was the flagship for a new cartridge and a new vision of a fighting handgun. It just arrived before the company could get its feet under it.
The Grandfather of Modern 10mms – The Bren 10
The genesis of this handgun starts with Thomas Dornaus and Michael Dixon, who teamed up with the legendary Jeff Cooper. They wanted a modern service pistol with more punch than the standard 9 mm and .45 loads of the day. That push led to the 10 mm Auto, initially loaded by Norma with a 200-grain bullet running around 1,200 fps. The numbers were bold for a duty pistol, and the goal was simple. Deliver magnum-like performance in a semi-auto that you could carry and fight with. Production began in the early 1980s, and the Bren Ten was the vehicle that brought that vision to life.

If the Bren Ten looks familiar, that is because its lines nod to the CZ-75. The slide rides inside, and the grip angle feels natural for most shooters. It is a DA/SA pistol with a frame-mounted safety that lets you carry cocked and locked if you prefer. Frames were stainless. Slides were carbon steel with blued or hard-chromed finishes. Sights were adjustable three-dots. The capacity varied by model, but the full-size 10 mm used 10-round magazines. It was a well-thought-out package, both on paper and in hand.
Multiple Models
Dornaus & Dixon offered several versions. The Standard full-size gun drew most of the attention, while the Special Forces models shortened things up. There was even a very scarce Special Forces Light that cut weight for carry. Collectors still chase those variants, which only adds to the pistol’s mystique today. A .45 ACP conversion was also part of the plan for some full-size guns.

So why did a promising pistol fade so fast? Part of the answer is business, not ballistics. Early production was rocky. Magazines were a headache, and some pistols shipped without usable magazines at all. Spare magazines were scarce and expensive. Add the challenge of feeding a brand-new cartridge, and the growing pains piled up. By 1986, the company had ceased operations, with total production likely under 2,000 pistols. The gun became rare almost overnight.
Miami Vice
Pop culture kept the flame alive. Miami Vice showcased a two-tone Bren Ten with a matte hard-chromed slide so it would pop on camera. When Dornaus & Dixon folded, the show moved Crockett to a Smith & Wesson 645. That shift mirrored the real world, where other makers stepped in to keep heavy-hitting autos on screens and in holsters.
The Bren Ten’s real legacy lives in the cartridge it launched. The 10 mm Auto had a rise, a stumble, and a comeback. Law enforcement flirted with it, then backed off when recoil and training costs collided with budgets. Downloaded 10 mm loads led to the .40 S&W, which took over duty holsters for years. Meanwhile, hunters and outdoorsmen kept the 10 mm flame burning. Today it is back in force, with pistols from Glock, SIG, S&W, and others. The idea that drove the Bren Ten never really died. It just needed time and broader support to mature.

Piece of History
If you find a Bren Ten in the wild, you are looking at a piece of handgun history. It is a snapshot of early 1980s thinking. Big energy. DA/SA controls and a safety that works like a 1911. The ergonomics still feel good, and the concept still makes sense. The pistol simply arrived with more ambition than a small company could sustain. That does not diminish the vision. In many ways, modern 10mm pistols are proof that the original idea was sound.
The Bren 10
I think that is why the Bren Ten holds attention decades later. It was brave. It tried to deliver real power in a practical package and got most of the way there. The execution faltered, but the direction was right. When you hear someone talk about the 10 mm as a proper field or defensive round, the Bren Ten is standing in the background. It might have been a short run, but it left a long shadow.
