STI to partner with Detonics Defense

Two high end, precision 1911 manufacturers, STI International and Detonics Defense, have entered into a business partnership in the hopes of producing better 1911s. It seems that the two seem to compliment each other, with STI having very good quality control and production facilities but lacking the theory and design ideas necessary for a “modernized” or “combat orientated” 1911. And Detonics having put alot of research into their design ideas and proof of concepts, but not having any of the mass production facilities of STI International.

Detonics Defense has 27 years of human factor research and training experience working with military, law enforcement and security personnel designing ergonomic and functional handguns.

“This partnership will give STI access to Detonics patents, R&D and human factors engineering talent,” said Jens Krogh, STI Director of Sales and Marketing. “With our manufacturing capabilities and their research, we feel it is a marriage of the best ideas with some of the best performing guns in the industry.”

“This partnership will help us achieve our long term goals of creating innovative human factor engineered products while having a partner fully dedicated to manufacturing excellence. We are excited to announce the results of Detonics and STI’s joint efforts to the firearms consumer later this year,” said Kevin Siddle, Detonics Director of Operations.

Both manufacturers make very highly priced 1911s ($1000 plus), STIs reputation is legendary in the competition world, but holds a lower position in the practical 1911 market. Honestly I’d never heard of Detonics Defense before this press release, but they must have some promising concepts if STI is willing to partner with them. But they appear to have been around since at least the 1990s or so. This is a video review I found of one of their different models

  • Frankly, the only interesting thing that Detonics has to offer right now is their striker fire control conversion for the M1911.

    • Giolli Joker

      The STX (that I googled thanks to your comment) is indeed interesting, but not shown on their website.
      In the article of BearingArms that I found, this very Mr Siddle comes up with the following sentence:
      “First, the 45 ACP has been proven to be the best stopping round because of the nature of the ballistic.”

    Detonics, defying 100 years of locked and cocked carry.

  • El Duderino

    That Detonics might be the ugliest non-zombie 1911 ever.

  • Jerry the Geek

    I like the Detonics … always have. And I do have a couple of STI’s in the safe. So, appreciate the merger of interests.

    As for the video …. someone has developed a bad habit of cocking his pistol with his finger on the trigger. Which is probably a good argument for not carrying loaded-and-hammer-down for some of us. (You know who you are)

  • Nicholas Chen

    That Match Master looks like my STI Steel Master.

    • They are pretty similar. The Steelmaster has more lightening cuts, and a minor PF tuned comp.

  • Raoul O’Shaugnessy

    Wait..Detonics is still around?

    • hikerguy

      I asked myself that same question. Evidently so, but I was surprised.

  • Manny Fal

    And both have crappy websites, Detonics doesn’t seem to work in fact. The blind leading the blind. Should have just hired some badass 1911 non poser user as consultant, I guess they couldn’t find one.

    • Giolli Joker

      I wouldn’t call STI blind… their website may be crappy, their products don’t seem to reflect it…

      • Manny Fal

        $100+ magazines say otherwise.

        • Giolli Joker

          No. They just say: “Expensive”.

  • Menzzer37

    Detonics had production issues. They can’t fulfill, and may never have, MTX orders. I have an outstanding order that’s over 14 months…

  • Comrade Misfit

    OOOOKaaayyy, but if Detonics is doing this to try for the new Army handgun contract, they need to rethink it. DoD procurement is a nightmare; probably why S&W partnered with General Dynamics.
