Description
Add a strong piece of Cold War-era U.S. Army small-arms documentation to your collection with this Technical Manual TM 9-1005-229-12P for the .45 Caliber M3 and M3A1 Submachine Guns. Dated December 1964, this manual is tied to the official Army repair-parts and special-tools documentation for the famous M3 “Grease Gun” and its improved M3A1 variant.
This manual represents an earlier support publication for the M3/M3A1 before the later 1969 operator and organizational maintenance manual replaced it. The 1969 TM 9-1005-229-12 states that it superseded TM 9-1005-229-12P, dated 14 December 1964, in its entirety.
Historical Significance
The M3 and M3A1 Submachine Guns are among the most recognizable American small arms of World War II and the early Cold War. Known to collectors as the “Grease Gun,” the M3 was designed as a simpler, lower-cost replacement for more expensive wartime submachine guns.
The NRA National Firearms Museum notes that approximately 650,000 M3 and M3A1 submachine guns were manufactured by General Motors’ Guide Lamp Division during World War II, with additional M3A1 production by Ithaca Gun Co. during the Korean War.
That gives this December 1964 manual strong collector appeal. It documents the Army’s support system for a weapon that began in World War II, continued through Korea, and remained present in U.S. military inventories into the Vietnam War era.
The M3 and M3A1 Submachine Guns
The M3 and M3A1 were compact .45 caliber submachine guns built around practical wartime manufacturing. They were light, rugged, and well suited for vehicle crews, armored units, support troops, and other personnel who needed a compact automatic weapon.
Army technical documentation describes the M3 and M3A1 as air-cooled, blowback-operated, magazine-fed automatic shoulder weapons. It also notes their telescoping steel wire stock, 30-round magazine, and major groups including the magazine, barrel, bolt and guide rod group, housing group, trigger and sear group, and receiver assembly.
The M3A1 is especially interesting because it simplified the original M3 design. Army documentation notes that the M3A1 changed the housing and bolt arrangement, including the removal of the M3-style retracting handle system.
What This Manual Covers
As TM 9-1005-229-12P, this publication is tied to the operator and organizational maintenance repair-parts and special-tools side of the M3/M3A1 manual family. A December 1964 higher-level maintenance manual specifically references TM 9-1005-229-12P for the maintenance allocation chart and identifies it as the operator and organizational repair-parts and special-tools publication for the Submachine Guns, Caliber .45, M3 and M3A1.
This manual is especially relevant for:
- M3 Grease Gun documentation
- M3A1 Submachine Gun documentation
- .45 caliber U.S. submachine gun reference
- operator and organizational maintenance research
- repair parts and special tools reference
- World War II, Korean War, Vietnam-era, and Cold War small-arms displays
- U.S. Army ordnance technical manual collections
- collectors completing an M3 / M3A1 manual set

Why This Manual Matters
The M3 Grease Gun represents one of the most practical American small-arms designs of World War II. It was built for fast production, compact carry, and simple battlefield use. Its continued documentation into the 1960s shows how long the M3 and M3A1 remained important in the Army’s small-arms support system.
This manual helps preserve the official parts and maintenance paperwork behind that weapon family. It is not a commercial guide or modern collector booklet. It is part of the Army’s technical publication trail for one of the most distinctive .45 caliber submachine guns ever issued.
For collectors, it pairs well with M3 and M3A1 displays, .45 ACP ammunition references, World War II armored crew equipment, Korean War small-arms collections, Vietnam-era vehicle crew displays, and U.S. Army technical manual libraries.
