The Lusa is a compact 9×19mm Parabellum submachine gun developed by INDEP of Portugal in 1983. Its name is derived from Lusitania, which was the Roman name for the Iberian region that covers present day central and southern Portugal and part of Spain. Although it was originally intended for military use, it was well-suited for law enforcement and ended up being marketed to bodyguards, VIP protection and special operations units. ==Development== INDEP was a defense industry company owned by the Portuguese Government. In the early 1980s, INDEP manufactured the HK G3 and HK 21 in Portugal under license from Heckler & Koch. This allowed for the importation of German weapons manufacturing machinery and technical know-how, which stimulated development of new firearms designs in Portugal. The Lusa marries some concepts from the HK MP5 and Uzi submachine gun without being too similar to either. The complete trigger housing is nearly identical to that of the MP5, however the other internals are greatly simplified. The bolt and carrier are one welded unit, and the action is a simple blowback, unlike the roller-delay system of the MP5. The Lusa fires from the closed bolt position in both semi- and fully automatic modes. However, the Lusa's barrel can be quickly changed without tools, like the Uzi. The Lusa uses a non reciprocating ambidextrous charging handle with no provision to lock the bolt to the rear, nor does the bolt lock to the rear upon an empty magazine. The rear sight is a simple diopter with screw adjustment. The body is formed from a sheet of stamped and welded steel. The weapon never enjoyed widespread production, and the project was halted in 1992, at a cost of 2.5 million dollars. The MP5 soon replaced this weapon's intended usage in the Portuguese police forces. In 2004, INDEP sold all the dies, tooling, fixtures and manufacturing rights to Stan Andrewski, owner of Stan's Gunsmithing in New Hampshire, Jerry Prasser, owner of (Recon Ordnance ) in Wisconsin, and Ralph Dimicco, co-owner of Riley's Gun Shop. The company was named LUSA USA. The LUSA was approved for sale as a semi-automatic by the BATFE (Bureau of Alcohol, Tobacco, Firearms, and Explosives) for the US civilian market. A select-fire model was available to law enforcement and government agencies, both foreign and domestic. Class III dealers could obtain one with the required LE demonstration letter. As of 2006, LUSA USA planned to offer conversion kits in .22 Long Rifle, .40 S&W and .45 GAP but distribution of these never materialized. (Choate ) side-folding stocks, sight rails and suppressors were available on a limited basis. Most models shipped with either a fixed stock or a collapsible stock. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lusa submachine gun」の詳細全文を読む スポンサード リンク
