PAM-2: Argentina's Improved 9mm Grease Gun

The M14, intended to replace multiple WWII-era firearms, suffered from critical design and manufacturing flaws. Despite its promising development, issues like receiver failures due to improper heat treatment and poor accuracy led to its short service life. The video details its origins, technical aspects, and the quality control failures that ultimately doomed its adoption.

The M3A1 Grease Gun, a $15 WWII submachine gun, is reviewed for its historical significance and surprisingly controllable full-auto fire. Despite crude construction, its low cyclic rate and .45 ACP chambering make it effective. The review includes a demonstration of its simple operation, disassembly, and a test of its ability to penetrate Level 3A soft armor.

The M3A1 Grease Gun, a WWII-era submachine gun, was developed as a cheaper, simpler alternative to the Thompson. Its design evolved to the M3A1, removing the crank handle for a finger hole cocking mechanism. Originally inexpensive to produce, registered M3A1s are now rare and costly collector's items.

The M3A1 Grease Gun, a simplified and inexpensive stamped sheet metal submachine gun, offered exceptional controllability due to its low rate of fire (~450 RPM). While its design prioritized cost-effectiveness over refined ergonomics, it proved reliable through multiple conflicts. Key features include a thumb-hole cocking mechanism and a wire stock with an integrated magazine loading tool.

The M3 and M3A1 Grease Guns were developed as a cost-effective, mass-producible alternative to the Thompson SMG during WWII. Designed by George Hyde and Frederick Sampson, these stamped sheet metal submachine guns featured a low rate of fire for controllability and a simple design. Despite initial magazine issues, the M3A1 improved upon the original, and the Grease Gun remained in US service until 1992, valued by tank and truck crews.

This American Rifleman TV preview from February 3, 2016, features a look at Melvin Maynard Johnson and his firearms. The "Rifleman Review" segment showcases the Taurus Millennium G2 pistol, and the "I Have This Old Gun" segment focuses on the M3A1 Grease Gun. The video promises historical firearm content and reviews of specific handgun models.
