Question: The Winchester Model 1911 SL Shotgun competed against a shotgun that remained in production until when?

full_context: Document 1: .40-60 Winchester: The .40-60 Winchester is a centerfire rifle cartridge intended for 19th-century big-game hunting. Nomenclature of the era indicated the .40-60 cartridge contained a 0.40 in diameter bullet with 60 gr of gunpowder. Winchester Repeating Arms Company necked down the .45-60 Winchester cartridge to hold a bullet with improved ballistics for the Winchester Model 1876 rifle. The lever-action Model 1876's advantage of faster loading for subsequent shots was eclipsed two years later by the stronger and smoother Winchester Model 1886 action capable of handling longer cartridges with heavier bullets. The .40-60 and similarly short cartridges designed for the Model 1876 rifle faded into obsolescence as 20th-century hunters preferred more powerful smokeless powder loadings of cartridges designed for stronger rifles. Winchester production of .40-60 cartridges ended during the great depression.
Document 2: Colt AR-15: The Colt AR-15 is a lightweight, 5.56×45mm, magazine-fed, gas-operated semi-automatic rifle. It was designed to be manufactured with the extensive use of aluminum alloys and synthetic materials.
Document 3: Winchester Model 37: The Winchester Model 37 (M37) Single Shot Shotgun is an American firearm. It was in production from 1936-1963 with 1,015,554 units made. This model was developed by Winchester with a standard visible hammer action for many years. The Winchester Model 37 uses a top-cocking lever, breakdown type of action with an automatic shell ejector. The first M37 shotguns were delivered on February 10, 1936 according to factory records. Notably M37 shotguns were not serial numbered.
Document 4: Winchester Model 1912: The Winchester Model 1912 (also commonly known as the Model 12, or M12) is an internal-hammer, pump-action, shotgun with an external tube magazine. Popularly named the "Perfect Repeater" at its introduction, it largely set the standard for pump action shotguns over its 51-year high-rate production life. From August 1912 until first discontinued by Winchester in May 1964, nearly two million Model 12 shotguns were produced in various grades and barrel lengths. Initially chambered for 20 gauge only, the 12 and 16 gauge versions came out in 1913 (first listed in the 1914 catalogs), and the 28 gauge version came out in 1934. A .410 version was never produced; instead, a scaled-down version of the Model 12 known as the Model 42, directly derived from scaled drawings of the Model 12, was produced in .410.
Document 5: Winchester Model 21: The Winchester Model 21 is a deluxe side by side shotgun. The shotgun's initial production run from 1931 through 1960 yielded approximately 30,000 guns. Winchester Repeating Arms Company ceased the main production line of this shotgun in 1960 and the Model 21 was sourced to the Winchester Custom Shop until the gun's retirement in 1991. New Winchester Model 21 production continues under license to Connecticut Shotgun Manufacturing Company.
Document 6: Browning BAR: The Browning BAR is a gas-operated, semi-automatic rifle produced by the Browning Arms Company in Belgium. The rifle loads from a box magazine detachable from a hinged floor plate. This rifle should not be confused with the M1918 military rifle, which is a completely different design, sharing no parts, though also referred to as the BAR. Browning introduced a redesigned BAR in 1966.
Document 7: M2 Browning: The M2 Machine Gun or Browning .50 Caliber Machine Gun is a heavy machine gun designed toward the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses the much larger and much more powerful .50 BMG cartridge, which was developed alongside and takes its name from the gun itself (BMG standing for "Browning Machine Gun"). It has been referred to as "Ma Deuce", in reference to its M2 nomenclature. The design has had many specific designations; the official designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications and low-flying aircraft. The M2 has been produced longer than any other machine gun.
Document 8: Winchester Hotchkiss: The Winchester Hotchkiss was a bolt-action repeating rifle patented by Benjamin B. Hotchkiss in 1876 and produced by the Winchester Repeating Arms Company and Springfield Armory from 1878. The Hotchkiss like most early bolt-actions had a single rear locking lug integral with the bolt handle, but was unique in feeding multiple rounds from a tubular buttstock magazine similar to the Spencer rifle. The .45-70 Hotchkiss was acquired in limited numbers by the US Navy as the M1879, and (in a slightly modified version) by the US Army and several state militias as the M1883, making it the first center-fire bolt-action repeater to be adopted by any major military (the distinction of first bolt-action repeating rifle to be a issued in great numbers as a standard military arm was the Swiss Vetterli 1869, which utilized very large rim-fire metallic cartridges).
Document 9: Mannlicher M1905: The Modelo 1905 is a pistol designed by Ferdinand Ritter von Mannlicher in 1899 and originally produced in Austria as the Mannlicher Model 1901. The Mannlicher Model 1901 was an improved version of the Model 1900, both of which were produced by Osterreichische Waffenfabrik Steyr (commonly known as Steyr). All of these models have the same basic design and operation, but minimal adjustments were made to improve each of them. The Modelo 1905 is the version of the Model 1901 that the Argentine Army purchased from Steyr in 1905. This semi-automatic pistol has a unique and elegant appearance due to the curve of the handgrip. It is single action and uses a blowback operation system to reload. Like its predecessors, the Modelo 1905 has a non-detachable magazine that can be loaded from the top with a stripper clip.
Document 10: .45-60 Winchester: The .45-60 Winchester is a centerfire rifle cartridge intended for 19th-century big-game hunting. Nomenclature of the era indicated the .45-60 cartridge contained a 0.45 in diameter bullet with 60 gr of black powder. Winchester Repeating Arms Company shortened the .45-70 government cartridge to operate through the Winchester Model 1876 rifle's lever-action. The Colt Lightning Carbine and the Whitney Arms Company's Kennedy lever-action rifle were also chambered for the .45-60. These early rifles' advantage of faster loading for subsequent shots was soon eclipsed by the stronger and smoother Winchester Model 1886 action capable of handling longer cartridges including the popular full length .45-70. The .45-60 and similarly short cartridges designed for the Model 1876 rifle faded into obsolescence as 20th-century hunters preferred more powerful smokeless powder loadings of cartridges designed for stronger rifles. Winchester production of .45-60 cartridges ended during the great depression.
Document 11: MAB PA-15 pistol: The MAB PA-15 ("Pistolet Automatique 15", also known as the "P-15" or "P.15 Standard") was designed by the Manufacture d'armes de Bayonne. The model number, 15, refers to the magazine capacity. When introduced, this was the first pistol holding a greater number of rounds than the 13-round Browning Hi-Power. The PA-15 was introduced in 1966 along with a short-lived 8-round version with a single stack magazine, the P-8.
Document 12: Winchester model 30: The Winchester Model 30 was an experimental self-loading rifle offered to the United States War Department as an alternative to the M1 Garand. Winchester Repeating Arms modified the design to a selective fire Winchester Automatic Rifle after military field trials favored the Garand. Development had not progressed beyond limited-production prototypes when official interest faded at the end of World War II.
Document 13: Stevens Model 77E: The Stevens Model 77E was the most widely used shotgun of the Vietnam War. The Model 77E was a short-barreled pump-action shotgun known variously as the "trench" or "riot" shotgun. The Model 77E had noticeably shorter stocks than similar United State military shotguns built by Ithaca Gun Company, Remington Arms, and Winchester Repeating Arms Company. These short stocks were intended to accommodate South Vietnamese soldiers, and the Model 77E was the first United States combat shotgun equipped with a rubber recoil pad. Model 77E shotguns were Parkerized with sling swivels and wooden stocks. Receivers were marked "U.S." and "p" proofmarks appeared on both barrels and receivers.
Document 14: Browning Auto-5: The Browning Automatic 5, most often Auto-5 or simply A-5, is a recoil-operated semi-automatic shotgun designed by John Browning. It was the first successful semi-automatic shotgun design, and remained in production until 1998. The name of the shotgun designates that it is an autoloader with a capacity of five rounds, four in the magazine and one in the chamber. Remington Arms sold a variant called the Remington Model 11 that was nearly identical but lacked the magazine cutoff found on the Browning.
Document 15: Winchester Model 1911: The Winchester Model 1911 SL Shotgun was a self-loading, recoil-operated shotgun produced by the Winchester Repeating Arms Company from 1911 to 1925. It was Winchester's first autoloading shotgun, but design flaws kept it from providing competition for the autoloading shotguns made by Remington Arms and Browning Arms Company.
