The X-911 was an American submachine gun designed by Walter E. Perrine and produced by Cam-Stat in prototype form only.
History[edit | edit source]
Designed in 1970 by Walter Perrine, the X-911 was advertised by a firm named Cam-Stat as a light and simple submachine gun that could be produced as a low cost. The weapon was marketed worldwide and touted to have multiple applications; a number of prototypes were produced, all in varying calibers, have been said to have been "thoroughly tested". The weapon was still in the prototype stage in 1979 and is assumed to have been shelved.
Design Details[edit | edit source]
Sporting rather modern looks for a submachine gun from the 1970s, the Cam-Stat X-911 utilized a rather peculiar hesitation-locked delayed blowback system assisted by a toggle joint that was patented in fourteen countries, with additional patents being filed as well. The weapon uses wooden furniture and takes Carl Gustav magazines with capacities of 15 and 35 rounds. The weapon's charging handle is a milled piece located on the top of the weapon.
The X-911 was touted by CAMSTAT as being very cheap to produce; Cam-Stat estimated that the weapon would cost about USD 38 to manufacture on the basis of "a single production run of 100,000 units". Cam-Stat also estimated that complete amortization of all tooling over said "single production run" would amount to USD 200,000; this is based on the assumption that the weapon was produced by a company currently in the arms manufacturing business.
The weapon's blowback system, as mentioned above, incorporates a toggle lock; the bolt comprises of a vertical pin hinge with one link of the toggle joint, with a spring-loaded plunger acting against the bottom portion of both links. When the weapon is fired, the bolt blows back after overcoming the slight angle of the toggle joint; this causes a "hesitation" effect as the bolt builds up some amount of force to overcome the resistance of the toggle and its plunger. The system is said to reduce recoil.
The weapon's forearm may be pivoted down to act as a makeshift vertical foregrip. The X-911 is touted to also be able to be converted for use in multiple applications; for instance, the X-911 could be converted into a "carbine" by making "minor modifications" to the weapon and adding a telescoping stock.

- The X-911 was marketed as a machine pistol, despite its dimensions leaning closer to that of a submachine gun.
