I Have This Old Gun: M1/M1A1 Thompson Submachine Gun
This video provides an in-depth look at the M1 and M1A1 Thompson submachine guns, detailing their development as cost-effective wartime solutions. Experts explain the significant design simplifications, including the elimination of the Blish locking system and the switch to a straight blowback action, which made production more efficient. Key changes like the removal of barrel cooling fins, the Cutts Compensator, and the adoption of a 30-round stick magazine over the heavier drum are highlighted, along with the M1A1's further refined fire control assembly.
