The Maxim Defense PDX pistol in .300 Blackout with a 5.5-inch barrel and arid finish (brand part no. 47822) was voted Best of SHOT 2019 by RECOIL Magazine, born from the SOCOM PDW solicitation to meet Tier 1 close-quarters demands in an 18.75-inch overall package. Maxim Defense builds the PDX around the patent-pending SCW system, reducing the stock length to 4 inches with an integrated bolt carrier group and interchangeable buffer weights, and the HATEBRAKE muzzle booster cuts recoil and flash while directing gas and concussion downrange. The pistol’s titanium, stainless steel, and aluminum construction is hard-anodized and weighs 5 pounds 11 ounces, with a 5/8×24 threaded muzzle and a nickel boron-coated trigger for a smooth pull. Among .300 Blackout AR pistols, this PDX configuration favors shooters who want subcompact, SOCOM-derived PDW performance.
