The Winchester 1300 shotgun was first introduced in around 1981, when the US Repeating Arms Company (USRAC) took over production of the ‘Winchester’ brand guns from the Olin / Winchester corporation. In fact, the model 1300 was a slightly modified version of the previous Winchester model 1200 shotgun, which was manufactured by Olin /Winchester between 1964 and 1980. With recent (mid-2007) closure of the USRAC factory production of the Winchester model 1300 shotguns, along with other Winchester brand guns, was moved to Winchester Repeating Arms Co; new guns will be manufactured by one of the FN ManufacturingCo subsidiaries located in the Morgan, Utah. The Winchester1300 shotguns are also known as the ‘Speed pump’, because of the very fast-cycling pump action, which makes these guns popular among both hunters and sport shooters. These shotguns also work well for home defence and security applications, especially with availability of relatively short-barrelled models with long magazines. The Winchester 1300 shotgun utilizes so called pump action, which is operated by sliding for end. For end is connected with bolt group with dual action bars. Receiver is produced from lightweight aluminium alloy, and the bolt locks into the barrel extension using a rotary bolt head with four radial locking lugs. Feed is from tubular under barrel magazines, which can be had in a variety of lengths / capacities. Barrels are quick-detachable; in ‘Defender’ configurations barrels have fixed cylinder choke; in hunting configurations barrels are usually fitted with replaceable chokes and a sighting rib. Standard furniture comes in wood or plastic varieties, finish and sights may vary from version to version.
