Beretta 92 Models
By Dennis Adler
When you fieldstrip all three of these Beretta 92FS-style CO2 pistols you end up with the same parts. The only difference is that the Crosman (far right) has a better magazine for loading, but the other mags work in the Crosman just as well. The full auto setting is selected by the safety when moved to the lowest position, allowing one pull of the trigger to fire the gun continuously until you let off. The select fire Umarex Beretta 92A1 has a different selector switch apart from the thumb safety.
The concept of parts interchangeability was pioneered by Samuel Colt in the 1850s to facilitate more efficient and precision manufacturing at his Hartford, Connecticut, South Meadows Armory. In a way, Colt even pioneered the moving assembly line with revolver and rifle components progressing along dedicated production lines, minimizing unnecessary movement. As noted in the book, Samuel Colt – Arms, Art, and Invention by Herbert G. Houze, within the Colt’s factory buildings there were “fifteen hundred machines, the majority of which were both invented and constructed on the premises. Every part of a pistol or rifle is made by machinery, and being made to gauge, is an exact counterpart of every other piece for the same purpose.” Every part was inspected for uniformity before going to assembly, and thus you had parts interchangeability. The efficiency of the Colt factory allowed guns to be built and assembled in large numbers, and for guns in the field (remember much of this occurred just prior to and during the Civil War) an armorer in a military unit or company could replace damaged or broken parts with spares that were identical and required very little hand fitting, if any. Henry Martyn Leland, the founder of both the Cadillac and the Lincoln Motor Car companies in the early 20th century, had worked for Colt’s during the Civil War where he learned the value of parts interchangeability. After Colt’s he took this skill to Springfield Armory and later Brown & Sharpe in Providence, Rhode Island, a precision tool making company, before setting off to Detroit and America’s emerging automobile industry. The significance of parts interchangeability has been realized globally by virtually all manufacturing, whether in the form of firearms, automobiles, hand tools, or appliances, and to the point of this article, air pistols.
