The Little Tom is highlighted as the world's first Double Action Only (DAO) automatic pistol, featuring a unique bi-directional magazine loading system. Its barrel disassembly involves pushing it back to release an oval lug from a dovetail slot. The internal mechanism demonstrates a specific trigger bar and hammer interaction for DAO operation.
The Little Tom, designed by Alois Tomiška, was the world's first Double-Action Only (DAO) automatic pistol, patented in 1908 and produced post-WWI. Primarily chambered in .25 ACP with a rarer .32 ACP variant, it featured a unique top-loading magazine and a simple barrel attachment for disassembly. Approximately 35,000 units were manufactured, with Austrian proof marks indicating production around 1921-1922.
