Parts are described in chapters organized by assembly-receiver, slide and magazine. Each part of each assembly-trigger system, magazine release, sights, etc are then described complete with markings and other identifying characteristics. Parts are differentiated by model and manufacturer, i.e. Colt, Springfield Armory, Remington Arms-UMC, Singer, Ithaca , Remington Rand and Union Switch & Signal. All Colt model and variation parts are also described where they differ from the .45 ACP part.
All military and commercial markings are listed by date or serial number range of use. Serial numbers are listed in twenty-six individual tables both by military and the individual commercial models, and by other manufacturers. An appendix contains a serial number listing organized both by manufacturing and shipping date. Serial numbers for British military, Canadian, Argentine, Norwegian, and Russian military pistols are also given.
Individual chapters and appendices provide detailed examinations of markings on receivers, slides and barrels, including military inspection and commercial markings, and photographs of all slide markings. Finishes are discussed for both military and commercial pistols by serial number ranges. Accoutrements and accessories are thoroughly explored and photographed including all belts, magazine pockets, and holsters.
A complete listing of all U.S. military Model 1912, 1916, M3, M7, and M15 holster manufacturers is included. U.S. military-issue ammunition in .45 ACP is described in detail. A photo-illustrated assembly/disassembly procedure shows the most efficient way to service the pistol.
