Thompson Parts
Tommy Gun • M1928A1 • M1 / M1A1
Keep the legendary “Tommy Gun” running. We stock genuine USGI and reproduction Thompson parts for the M1928, M1928A1, M1, and M1A1 submachine guns — magazine pouches, drum covers, leaf sights, buttstock screws, brass oilers, and WWII cleaning rods. Correct-spec gear for collectors, reenactors, and restorers of America’s most iconic SMG.
Thompson SMG Parts
Few firearms are as iconic as the Thompson submachine gun. From the streets of the Prohibition era to the beaches of Normandy, the “Tommy Gun” earned its legend in .45 ACP — and we stock the parts to keep one correct and running. Our 6 genuine USGI and faithful reproduction components fit the M1921, M1927, M1928, M1928A1, M1, and M1A1 Thompsons, part of our wider military surplus parts lineup.
Magazine, Drum & Sight Parts
Feed and aim it like the originals. The original WWII USGI Thompson Magazine Pouch is a five-cell, lift-the-dot canvas carrier for 20-round .45 ACP stick mags — genuine Lend-Lease issue and a collector favorite. If you run the iconic drum, the stamped-steel Thompson Drum Cover is the correct front cover for the 50-round L drum on the Model 1921, 1927, and 1928. For the rear sight, the reproduction Thompson Leaf Sight Slide is a drop-in elevation slide for the Lyman adjustable assembly on the M1928 and M1928A1, and the steel Thompson Buttstock Screw reinforces the wood stock on the M1, M1A1, and M1928A1 while accepting a sling swivel mount.
USGI Field Accessories
Round out the kit with the small stuff that lived in the buttstock trap. The original WWII USGI Thompson Oiler is a brass, black-crinkle-finish dropper that fits the M1928 and M1928A1 stock, and the original USGI WWII Thompson Cleaning Rod is genuine brass with a threaded tip that accepts standard .45-caliber brushes and jags, fitting the M1928, M1928A1, M1, and M1A1. Whether you’re restoring a semi-auto clone or completing a display, these are the correct details.
