Our Assessment: The RPB SAP M10 Open Bolt Pistol was a semi-automatic version of the M10 submachine gun, which was designed by Gordon Ingram in 1964. The M10 was produced by Military Armaments Corporation and was available in 9mm and .45 ACP, and a smaller version called the M11 in .380 ACP. The M10 was notable for its low cost of production, high rate of fire, and small size. RPB Industries later bought up the assets of Military Armament Corporation and resumed production under the RPB banner.
The RPB SAP M10 Open Bolt Pistol was submitted to the BATF for approval in 1978, and was approved as a semi-automatic handgun. Despite its low price and aggressive marketing, the gun did not gain wide acceptance among legitimate buyers. However, it became a popular weapon among criminals, particularly in the drug wars of South Florida in the early 1980s.
During this period, criminals would buy the semi-automatic version of the M10 SAP and then modify it to fire in full-auto, making it a highly sought-after weapon for criminal gangs. Law enforcement officials seized around 200 M10 SAPs during criminal investigations, and the use of automatic weapons was relatively rare among American criminals. The M10 SAP was one of the most popular illegal machine guns of the era.
There were a few others, but this one made up the lion’s share of the open-bolt semi-auto pool. Despite a valiant struggle and a court case lost, the 1982 reclassification shut off much of RPB’s sales, and the company folded. Claim this Rare Gem of firearms history today that has been grandfathered in. Because it is a pre 1982 production it is fully legal to sell as Open Bolt. Anything after 1982 is illegal so we are lucky here! This one also comes with a rare Cobray Steel M10 magazine. Please see details below and Good Luck!!!
