The Model 1. 90. 2 is a semi automatic pistol developed by famous American firearms designer John Browning and produced by the Colts Patent Firearms Manufacturing Company in the early 2. The Model 1. 90. 2 was not a new design, but rather an incremental improvement upon the nearly identical M1. Sporting Model, the 1. Military model, and the 1. Pocket Hammer model. The 1. 90. 2 Sporting model was so similar to the 1. Military Model featured a different serial range as did the 1. Pocket Hammer model. The 1. 90. 2 Military Model featured a square and lengthened grip frame with an additional round in the magazine, while the 1. Pocket Hammer featured a shortened barrel and slide but retained the Sporting model grip frame. The Colt M1. 90. 5. ACP pistol would be derived from the same lineage, also with a different serial number range. DevelopmenteditIn the late 1. United States, were evaluating or in the process of adopting a state of the art semi automatic service pistol to replace the revolvers in use at the time which were perceived to be outdated. American gun designer John M. Browning wished to join contemporaries such as Hugo Borchardt and Georg Luger in designing a marketable semi automatic pistol. Colt Diamondback Serial Numbers' title='Colt Diamondback Serial Numbers' />Browning partnered with the Colts Manufacturing Company which was hoping to capitalize on the interest in service pistol modernization by procuring large and profitable government military contracts. Their first collaboration produced the Model 1. Colt Diamondback Serial Numbers' title='Colt Diamondback Serial Numbers' />U. S. military enough to lead to the purchase of a few hundred Model 1. The Model of 1. 90. The Mauser C9. 6, 1. Luger, and Colt 1. The Mauser tended to be considered the most developed or mature in terms of mechanism, featuring a reliable action protected from the elements, manual safety, and a hold open indicating the last shot had been fired and easily convertible to carbine form, however the pistol had reached its developmental peak. The Luger, like the Colt, in 1. The Colt was ergonomically the opposite, having poor balance and a crude grip, it also lacked safety mechanisms the abandoned and unpopular sight safety was exchanged for no safety at all, and was considered more open to the elements. The Colt 1. 90. 2 sporting model, used in 1. Swedish tests lost out to the FN Browning 1. MM, was also found to be not quite sufficiently reliable but the Swedes also mentioned the ergonomic drawbacks. The value of the Colt, however, was that its. ACP cartridge was considered superior to both German pistols cartridges and a step in the right direction the Swedes mentioned this virtue. The Colt 1. 90. 2 had room to develop, while the Mauser was already mature and not subject to improvement. The Luger on the other hand would be developed at about the same pace as the Colt 1. ACP Colt 1. 90. 5s and 4. ACP Lugers faced off, although in the end both pistols showed insufficient promise in the heavier caliber, and as the United States was committed to the. ACP, the basic 1. ACP and the Luger had a tad more stretch and would find the greatness with the 9 mm parabellum cartridge that would never come to the Colt 1. However the Colt pistols helped sell the semi automatic pistol concept in the United States and would contribute to the development of the Colt 1. Design detailseditThe M1. Model of 1. 90. 0 by the simplification of its internal mechanism and a reduction in the number of internal parts. Browning and Colt also adopted the suggestion of the U. S. Military to add a slide stop to the design. The problematic pivoting rear sight safety of the M1. Another shortcoming in the M1. British military, who discovered that the pistol had a tendency to fire when dropped. In the M1. 90. 2, the firing pins length was reduced to be less than that of the slot it moved in, decreasing the likelihood of such an occurrence unless the firing pin was actually struck by the hammer. The Model of 1. ACPcartridge as was the earlier M1. The M1. 90. 2 pistol for the most part also shared the same hard black rubber grips which were standard on the Model 1. The vast majority of Model 1. Colt Royal blued finish, but rarely nickel and silverplated models are encountered, as well as various custom finishes. On some early production Model 1. The hammer of 1. 90. Earlier production pistols featured either milled straight line or cross cut checkered slide serrations on the forward end of the slide, which were deleted in later years of production. Although the M1. Colt was progressive enough to recognize that commercial merchandizing of the pistol also offered potential revenue and introduced a sporting version of the pistol with a few minor changes. Neither the Military or Sporting versions of the pistol had a manual safety. The Colt 1. Two, referred to by Colt as the high spur hammer and a rounded hammer, referred to by Colt as the stub hammer, were carryovers from 1. Eventually, by 1. The 1. 90. 2 Military Model, started production with stub hammers only. The third hammer, which did not see use until late 1. Military model hammer from about 1. Due to hand polishing of Colt Automatics through the 1. Model. 4. 5, the depth of any pistols markings might vary on the same pistol as well as the weight pistols might vary as much as an ounce when compared. The 1. 90. 2 Militaries were slightly heavier than the sporting models due to the extended square frame and lanyard loop. VariantseditOffered between 1. Military Model 1. The Military model featured the mechanical slide stop and had a lanyard loop on the heel of the grip, it was also slightly heavier. Military models produced prior to 1.

Sporting Models still outsold the military models, 6,9. Sporting Model ended in 1. Perhaps unexpectedly, with the end of Sporting model production, the Military Model sales actually began to decline until 1. Model 1. 90. 5. 4. ACP probably cutting significantly into sales improvement, and then the Colt 1. ACP came on in 1. Model 1. 90. 5, the Model 1. Perhaps this contributed to a jump in sales, as demand for the Colt 1.

ACP, the round for which it is chambered not to be confused with the shorter cased. ACP, and was the first handgun to utilize short recoil operation. It was developed from John M. Brownings earlier prototypes in the late 1. The United States military tested the design against other semiautomatic pistols by European makers, and adopted some versions forward trial use. The M1. 90. 0 and variants were also offered commercially. Variants included the Model 1. Sporting, Model 1. Military, Model 1. Pocket only in. ACP models the. ACP model was a different design, and the Model 1. ACP cartridge. The designs of 1. M1. 91. 1 pistol. Unlike the designs of other early semi automatic pistols, Brownings design used a full length slide that covered the full length of the barrel, as opposed to other designs which utilized a barrel and bolt that slid in grooves machined in the frame. In the Browning design, the slide fitted into rails in the frame, and was integral with the bolt. The barrel rode in locking grooves machined into the interior of the slide, but attached to swinging links secured to the frame, one at the front and one at the rear. When the slide is forward i. Upon recoiling, the barrel and slide move backwards a short distance, locked together, until the arc of the links pulls the barrel downwards, disengaging it from the slide and halting its rearward motion. The barrel then stops moving, while the slide continues rearwards, extracting and ejecting the fired cartridge case and then returns forward, loading a fresh cartridge from the magazine. The barrel is caught, and moved forward with the slide, the camming action of the links lifting it again to lock into the matching grooves. This is identical to the modern style of short recoil action as developed for the later M1. The M1. 91. 1, and most other pistols since, found that it was only necessary to use a single rear link and locking grooves in the rear. When the slide retracts, only the rear of the barrel is dropped, causing it to tilt relative to the slide, while a fixed barrel bushing holds the front of the barrel in place when the slide is in battery, yet allows for movement of the slide and barrel. This approach was found to work perfectly well, and saved in complexity, cost of manufacture, as well as simplicity of assembly and disassembly. The new design also featured a new cartridge, the. Automatic Colt Pistol. Despite the name, this cartridge used a. Special switched from heeled bullets to smaller diameter inside lubricated bullets, yet retained its original. Magnum in the 1. 93. This was a larger caliber bullet than used by other contemporary designs, which were predominantly 7. Tokarev7. 6. 32. Mauser,. ACP, etc., yet fired at similar velocities, giving more power. The. 3. 8 ACP was also a much faster cartridge than the. Long Coltrevolver cartridge in service at the time, which fired a 1. Colt was also experimenting with a. Model 1. 90. 0, as reported to the Ordnance Department during testing. Like the. 4. 1 Long Colt, this probably used a. The poor performance of the. Long Colt in combat in the PhilippineAmerican War of 1. Colt, and eventually led the War Department to specify a minimum caliber of. The prototype. 4. Colt automatic cartridge was never produced in production quantity, but the concept anticipated the development of the. S W by over 9. Colt did produce a few Model 1. Model 1. 90. 2 Military Models the 1. Military was an improved M1. One of the. 4. 1 pistols is on display in the Connecticut State Library, Hartford, CT the birthplace of Colts Manufacturing Co. The most prominent feature of the Model 1. When pushed down the safety blocked the firing pin, when pushed up it performed as the rear sight. This gave an immediate visual indicator of whether the safety was on or off when one went to aim the pistol, without resorting to feeling for the safety lever. The first 1. 90. 0s were equipped with rear milled slide grooves but when it was found that this could interfere with the sight safety one could inadvertently flip the safety on or off while manipulating the slide the milled slide grooves were moved to the front. This safety was used in about the first 3,0. Colt then installed a conventional rear sight and eliminated the sight safety although the cut in the slide remained but was plugged. The grooves, remained in the front of the slide. There are earlier sight safety M1. Although Colt considered a new firing pin safety mounted on the left side of the slide with one prototype, it did not produce such a model. This was possibly a mistake as the lack of safety features probably affected sales the recommended way to carry a safety less Colt automatic was with an empty chamber, requiring the user the rack the slide to chamber a round before firing which made it slower to get in action and required two hands, as well as making it impossible to render the weapon safe after firing a partial magazine, without dropping the magazine and extracting the chambered round, itself a dangerous operation in a gun without a safety. This was a major complaint of the military when they tested it, something Colt was for some reason loath to fix in the 1. The only exception was the new small sized Colt 1. Pocket Hammerless, a completely new design with a grip and frame thumb safety at the start of production in 1. It is possible that Colt found it cheaper to introduce the features into a new model, and the sales of the 1. Pocket Hammerless were spectacular in comparison to the 1. By contrast, Mauser C9. Lugers had manual thumb safeties from the outset. The Model 1. 90. 0s were initially fitted with distinctive high spur hammers until approximately serial 2. As approximately 1,4. M1. 90. 0 high hammers were left over when the M1. M1. 90. 2 sporting model, the 1. M1. 90. 0 starting at serial 4. M1. 90. 0s were produced. Stub hammers may also possibly show up in some retrofitted earlier pistols. Numbers at this time can only be considered approximate. Collectors need to continue to post and communicate observations of surviving pistols. US War Department testingeditThe United States War Department solicited designs of semiautomatic pistols in 1. Mauser C9. 6 Broomhandle, the unusual blow forward action. Steyr Mannlicher M1. Browning designed Colt M1. Testing consisted of accuracy, penetration, and reliability tests, ergonomics or ease of use testing, and torture tests. Ergonomics were considered very important, as the pistol was intended for use by cavalry, which meant it had to be readily operated and reloaded from horseback. Torture tests included a dust chamber and a rust test.
