     This was the most commercially successful of all of the compact Ingram submachineguns. This weapon was made by one of the successors to the MAC corporation, specifically SWD Incorporated, who had the rights to the MAC 10 and 11 submachineguns. The compact M11/9, also called the M11/Nine, was a new design not produced by Gordon Ingram but instead following his products. The M11/Nine upper receiver was built from 16-gauge sheet steel, formed and with a steel barrel trunnion at the front. The lower receiver was made of heavier 14-gauge sheet steel. It was the longer receiver that allowed the M11/Nine to operated with the 9x19mm round without pounding itself to scrap. The longer length of travel for the bolt, as compared to the Ingram M11, allowed the energy of the 9x19mm round to be absorbed by the action, however the design still had the very high cyclic rate of fire of the original Ingram M11.

     The cocking handle of the M11/Nine is smaller than that of the earlier Ingrams. It also does not rotate to lock the bolt as in the other weapons. An additional obvious change in the design of the M11/Nine is the stock. The basic design of the stock still slides in the bottom of the lower receiver. But the new stock is much easier to extend and lock in to place for use. The butt of the stock is a shallow V form that seats solidly on the shoulder, in spite of the small overall size of the weapon. To extend the stock, a finger is inserted into the rear of the butt and the stock pulled to the rear. The butt section of the stock folds down and locks in place while the remained of the stock extends out from the bottom of the receiver and then locks into place.

     The bolt and a number of internal parts are steel castings while the magazines were considered a new and improved idea on the originals. The reason for the excitement for the new magazines was that they were among the first plastic magazines for an automatic weapon. Made from a new “space age” plastic called Zytel, the magazines were very light and relatively inexpensive. Excitement over the new magazines was short-lived when they were found to break at the feed lips and the body of the magazine to split. There were new magazines forthcoming from the company that were improved as ther were made in one piece. Steel magazines also came out from outside suppliers for the M11/Nine. Production of the weapons for the commercial market continued until 19 May, 1986, made the manufacture of transferable weapons for the public almost impossible. A small number of M11/Nine weapons continued to be made for a while for supply to Law Enforcement sales and exports. A “rate reducer” was offered from SWD for the M11/Nine as an aftermarket addition to the weapon. The reducer lowered the cyclic rate of fire to around 750 rounds per minute. It was not a commercial success and few were sold.

 

Designed by the SWD Corporation who purchased the rights to the Ingram Model 11 submachinegun design and the Cobray logo in 1982. In 1983, the SWD Corporation released their new submachinegun, the M11/Nine onto the market. The name indicates that the weapon is chambered for the 9x19mm round, but is generally the same size as the original Ingram M11 but with a longer receiver. This illustration is the right side of an unloaded M11/Nine with the stock in the folded position. The stock has been changed so that it is more comfortable and secure to shoulder. It is also easier to employ as it can be grasped with a finger though the buttstock loop and the stock extended to stop when engaged by the stock catch. The cocking knob at the top of the receiver is flat and has no sighting groove down its center. The cocking knob also cannot be rotated to lock the bolt in position. The safety is the same sliding model as found on the Ingram submachineguns on the right side of the trigger guard. This specimen has its safety set in the “FIRE” position. PHOTO CREDIT: Kevin Dockery

The left side of an SWD M11/Nine submachinegun. The general layout of the weapon follows that of the Ingram M11, only with a longer receiver to allow for the weapon being chambered for 9x19mm. The rotating selector switch is in the same location as the Ingram designs. The switch is rotated to pint at the SMG marking, indicating that the weapon is set for full automatic fire. The takedown pin in front of the selector switch is also of a different style than that of the Ingram M10 and M11 weapons. The central pin inside of the larger outer pin locks the assembly together. To removed the pin, the inner lock must first be moved out of the way, usually with the point of a bullet or cleaning rod. With that pin unlocked, it can be pushed through and out of the weapon on the right side. Then the larger outer pin is drawn out on the left side. Just above the hinge pin on the flat portion of the folding stock assembly can be seen the Cobray logo. PHOTO CREDIT: Kevin Dockery
