Not to be confused with the KAC SR-16.

The Robinson S.R. Model 16 9mm Machine Pistol, also known as the Robinson Model 16 or SR-16, was a conceptual Australian machine pistol that was designed by Russel Robinson.

History[edit | edit source]

In the early 1940s, Russel Robinson designed a "constant recoil" machine pistol known as the SR-11. It was tested against the STEN Mk V and the MCEM-2 in trials conducted by Maj. Eric Hall of the United Kingdom Ordnance Board. The SR-11 was deemed to be significantly more accurate in fully automatic fire compared to the other two weapons, but not as much in semi-automatic fire; as such, the Ordnance Board recommended Robinson to redesign the SR-11 so that it would be accurate in semi-automatic fire while still retaining its accuracy in fully-automatic fire.[1]

What would become of this would be known as the SR-16, which featured some major design changes compared to the SR-11, such as a forward-placed sear and a conventional firing pin. However, apart from some firing fixtures, no complete SR-16 was ever built. No subsequent attempt was made to build the SR-16 as by then there was no requirement for any more automatic weapons in the United Kingdom due to the adoption of the Patchett gun and with Russell moving to the United States.[1]

As the weapon was essentially a further development of the SR-11, the basic action would have been practically the same, featuring an auto-ejecting magazine and a free-floating rotating barrel. However, it would have featured a conventional firing pin and a forward-placed sear. The weapon would have been fed from 16-round magazines.[2]
