The final wartime revision of the Thompson Submachine Gun, the M1A1 was on paper made obsolete by the M3/M3A1, but would continue to serve as late as the Vietnam War. Blade front and fixed peep rear sights, with a horizontal handguard, machined receiver with "CLG" and "FJA" stamps. The trigger housing is mixed numbered and "S" marked, with dual control switches, grooved pistol grip and fixed buttstock with steel buttplate. Bolt is M1A1 pattern, with a fixed firing pin on the bolt face and no provision for a Blish lock or oiler.

Fine, with 95% restored parkerized finish, showing areas of mostly shallow pitting under the finish, some faded markings, and scattered handling marks. The wood has been sanded, with minor scuffing and dings. Mechanically excellent.
