Maxim Defense’s Integrally Suppressed PDX-SD, Now in 300BLK and 7.62

We don’t know where you come down on the age-old debate of what makes the best home defense firearm (let alone truck gun). Whether it’s the pistol, the rifle, or the shotgun, all have their own very devoted adherents and dedicated fans who are absolutely convinced of their rightness and the moral rectitude of their particular choice.

Whatever your opinion may be, more people have been swayed in recent years toward so-called person defense weapons or PDWs. They’re usually chambered in smaller rifle or pistol calibers and have short barrels. That makes them highly maneuverable in tight quarters and plenty effective at close ranges.

Now comes Maxim Defense with their new integrally suppressed PDX-SD in two new calibers. Not only is it very small, quiet, and maneuverable, it’s now chambered in a couple of larger (bigger than 5.56) calibers, 300BLK and 7.62.

No, it’s not cheap and yes, you’ll need two tax stamps (although they sell a version that’s fitted with a brace). But at just under 24 inches long (collapsed), this thing looks like lots of quiet fun with plenty of punch in a very compact package.

Maxim Defense, premier manufacturer of precision firearms, suppressors, and accessories, is proud to announce the Maxim Defense PDX-SD personal defense weapon with integrated suppressor is now offered in .300BLK and 7.62x39mm chamberings. The PDX-SD embodies performance, convenience, and silence in a single package.

The PDX-SD encapsulates power, convenience, and silence in a remarkably compact package. Born out of significant engineering achievements and meticulous attention to detail, this short 5.5-inch barreled PDW comes chambered in 5.56mm, and now .300BLK, and 7.62x39mm. Specially designed for compactness without sacrificing performance, the PDX-SD sets a new benchmark in the firearm industry. The built-in “soup can” silencer, with its impressive outer diameter of 2.25 inches, significantly reduces noise and gas emissions, making this weapon stealthier and more comfortable to operate.

“The PDX-SD is a testament to Maxim Defense’s knack for innovation and relentless pursuit of perfection,” said David Farrell, Vice President of Sales, Maxim Defense. “The addition of these two popular chambers makes the PDX-SD an exceptional personal defense weapon.”

The PDX-SD is not just a combination of a rifle and a suppressor. Instead, Maxim Defense conceived it as an integrated system where each component works harmoniously. This symbiotic relationship between the rifle and the suppressor allows for efficient maintenance, easy upgrades, and replacements. On the range, the PDX-SD showcases its superiority. It shoots like a high-end competition gun and remains impressively quiet and balanced, thanks to the finely-tuned gas system. With an overall weight of 7.6 pounds, it is designed to provide a comfortable shooting experience, making it an exceptional tool for defense and tactical operations. If you are looking for a compact yet powerful firearm that never compromises on stealth and performance, the PDX-SD is an excellent choice.

  1. $3,695.00, yikes.
    Some will buy it, maybe even me if a ‘Kali-Key’ fits in it…

      1. I’ll need to see one in person.

        Does Jeremy S. have stocking dealers in central Florida?
