Ati Gsg Mp40p 9mm 10.8" 25rd Blk

The ATI GSG MP40P 9mm is a faithful semi-automatic reproduction of the iconic World War II MP-40 submachine gun, engineered as a pistol configuration without a stock. Manufactured by American Tactical Inc. and GSG in collaboration, this 10.8-inch barreled firearm represents the most historically accurate MP-40 variant importable into the United States in recent decades. Built entirely with new parts manufactured to comply with current U.S. importation regulations, the MP40P bridges historical interest with modern legal requirements while maintaining the distinctive profile collectors and military history enthusiasts recognize.

Chambered in 9mm Luger, the GSG MP40P feeds from 25-round magazines, delivering the same intermediate cartridge ballistics the original platform was designed around. The 10.8-inch barrel length balances velocity retention typical of the 9mm cartridge with a compact overall package. At 11.63 pounds unloaded, the firearm reflects the mass distribution of its predecessor while meeting modern semi-automatic platform standards. The black finish provides a durable, low-profile appearance consistent with tactical and collector aesthetics. The pistol configuration—lacking a buttstock—classifies it within federal regulations as a firearm rather than a short-barreled rifle, eliminating NFA registration requirements that would apply to stock-equipped variants.

This platform appeals to military history collectors seeking functional reproductions of WWII-era weaponry, 9mm platform shooters interested in historically significant designs, and those seeking a unique semi-automatic firearm with substantial collector value. Range training with period-correct ergonomics, historical reenactment applications, and display-quality collection purposes represent typical use cases. The MP40P requires standard 9mm ammunition and operates on proven blowback principles established across decades of MP-40 service worldwide.
