Colt 1903 in US Military Service (and for the OSS)
The Colt Model 1903 Pocket Hammerless, or Model M, saw significant US military adoption during WWII, particularly by intelligence and special operations units like the OSS. While initial military interest was low, the need for compact sidearms led to procurement of over 17,000 .32 ACP and 3,000 .380 ACP pistols. Late-war production saw cost-saving changes like Parkerized finishes and updated sights and slide serrations.
