We had the chance to shoot a couple of the lesser-known submachine guns used in World War II, a German MP41 and an Italian Beretta 38/44. Both are pretty typically submachine guns, firing 9mm Luger from open bolts with fixed firing pins and simple blowback actions. They both have solid wood stocks (the MP41 is basically an MP40 with that in place of an underfolder) and bottom-mounted magazines. The MP41 uses a semi/full selector button, while the Beretta has separate triggers for semi and full auto fire.
The MP41 is a fine weapon, but my preference is for the Beretta. It is a bit shorter and handier, and just feels more controllable in my hands. This particular model (the 38/44) was the final iteration of the Beretta M38 family used during the war, and it would continue to be produced for international sale during into the 1960s under the designations A4 and A5.
