Rare Armaguerra OG-44 Shows Italy’s SMG Design Ahead of Its Time

Ian McCollum of Forgotten Weapons got rare access to Beretta's in-house reference collection during the company's 500th anniversary celebration, and he came out with footage of a gun almost nobody has seen running: the Armaguerra OG-44, an Italian submachine gun with only 14 examples ever made.

Snapshot

McCollum walks through the OG-44, a late-war Italian SMG built by Armaguerra in Cremona from a 1942 design by Giovanni Oleani. He argues the gun is far more advanced than its obscurity suggests, pointing to its stamped-steel construction and a forward-weighted bolt layout that predates similar solutions credited to later Cold War designs.

Key points

• Redesign for production: The original milled 1942 OG-42 was reworked in 1944 into a stamped-steel gun, dropping its proprietary magazine in favor of the widely available Beretta Model 38 magazine, per McCollum.
• Forward-weighted bolt: McCollum highlights a 1.9-pound (860 g) bolt with mass pushed forward over the barrel, reducing rate of fire to roughly 500 rounds per minute and aiding muzzle control, a layout he says predates the Czech vz. 23 and Uzi approach.
• Compact folding stock: The stock folds tightly under the barrel and includes a padded cheek-weld section, which McCollum calls more comfortable than typical thin folding-stock designs.
• Hardened, replaceable ejector: Since stamped steel is too soft for repeated case ejection, Armaguerra fitted a separate heat-treated ejector that slots into the receiver and can be swapped out.
• Unique takedown: A threaded guide rod doubles as a cleaning rod and secures the internal recoil spring, part of what McCollum describes as a surprisingly simple disassembly for an open-bolt gun.

Quick take

McCollum's larger point is that the OG-44 deserved a postwar future it never got. Armaguerra folded before guns like the Walther MPK/MPL or Franchi LF-57 defined the stamped-steel SMG era, so this design's innovations went largely unnoticed. For readers into small arms history, it is a good look at how far ahead of its time an obscure wartime prototype could be.
