Postwar US Caliber .38 Revolvers

After World War II, .38 Cal. revolvers continued in use and even were supplemented with new models from Colt or Smith & Wesson plus Ruger as a new supplier. The adoption of the M9 Beretta Automatic Pistol in the mid to late 1980s led to the replacement of most revolvers in the U.S. military.

The "Revolver, Caliber .38 Special" was procured from commercial manufacturers with at least six types in Army and Air Force inventory, as documented in TM 9-1005-206-14P/1 dated February 1971. The models listed are:

Model Stock Number
Colt, Detective Special, 2-inch Barrel 1005-726-5786
Colt, Police Positive, 4-inch Barrel 1005-716-2838
S&W, K-38 Masterpiece, M14, 6-inch Barrel 1005-830-2497
S&W, Military & Police, M10, Square Butt, 4-inch Barrel 1005-214-0934
S&W, Military & Police, M10, Round Butt, 2-inch Barrel 1005-937-5840
S&W, Military & Police, M10, Round Butt, 4-inch Barrel 1005-937-5839

The same TM had a later edition dated August 1985 that covered only two .38 pistols, presumably the only ones still officially in inventory:

  • S&W, Military & Police, M10 (3 models, see MP in NSN list)
  • Ruger Service Six, 4 inch Barrel M108 (3 models, see S6 in NSN list)

The Ruger pistols were brought into the U.S. military in the 1970s.
