Reviews
The Reactor19 feels different the moment you pick it up. Clean machining, thoughtful cuts, and real attention to detail. You can tell it was designed by people who actually shoot. On the range, it shoots flat and soft, and the dot is easy to track; it barely leaves my sight picture. Working with Arc Division was just as impressive: great communication, no corporate runaround, and a genuinely personal experience from start to finish.
Best there is out there when it comes to a ported slide needless to say that you get a what you pay for.
