Hi Ted,

The Vz.24 and PPSh sub-machineguns come to mind

But seriously, the rule of thumb is each inch of barrel length makes a twenty-five feet per second difference in muzzle velocity. So, just to keep to even numbers, take the six inch difference in barrel length between the test barrel (eleven inches) and the Vz.52 barrel (five inches), multiply that six inches by twenty-five feet per second to get one-hundred and fifty feet per second. Subtract that from the advertised 1647 fps and get about 1517 fps.

Very best,

Kyrie
