Manufacturing History of Ingram-MAC Type Firearms

By Frank Iannamico

In 1964, while working at the Erquiaga Arms Company, Gordon Ingram fabricated a compact submachine gun he chronologically designated as his Model 10.

Duly impressed with Ingram’s M10 as the perfect covert weapon, WerBell struck a tentative deal with Ingram, whereby he would take several of his submachine guns to Vietnam, and demonstrate them along with his Sionics suppressors. No Sionics made suppressors had yet been designed for the Ingram Model 10. The .45 caliber suppressor taken to Vietnam had been designed and built by Gordon Ingram.

Despite all of the previous rejections of his Model 10 submachine gun by the firearms industry, the suppressed weapon was an immediate hit in Vietnam. WerBell immediately contacted the Sionics Company officials back in Georgia, instructing them to contact Gordon Ingram and begin negotiations for the rights to manufacture his Model...
