The Grizzly Win Mag pistols were conceived, invented, designed, engineered and developed in the 1980s by the sole inventor, Perry Arnett, who licensed his patented design for an interchangeable caliber automatic pistol (U.S. Patent #4,253,377) to L.A.R. Manufacturing Inc. The L.A.R. Grizzly was the most powerful semi-automatic pistol ever commercially produced (The Mark V was chambered in .50 AE to compete with the IMI Desert Eagle). ==Background== The LAR Grizzly pistol was a modified Colt M1911 style pistol with oversize components designed to handle larger, more powerful cartridges than could be used in the standard size 1911 pistol. Between 1983 and 1999, it was produced in versions capable of firing 6 different cartridges. All guns were hand fitted and capable of high accuracy. The Grizzly is an oversize of the Colt M1911 design, and most parts are interchangeable with those of the standard size pistols of other manufacturers. The Mark I and Mark II models, offered in the mid 1980's were developed to fire the powerful .45 Winchester Magnum round. At various times, conversion kits were sold allowing the pistol to fire other rounds, including .45_ACP, 10 mm Auto, and .357 Magnum. Later, the Mark IV model was designed specifically to handle high pressure .44 Magnum loads, and the Mark V was designed to chamber the still more potent .50 AE. The 357/45 Grizzly WinMag .357-.45 GWM was a powerful wildcat round designed for the LAR Grizzly pistol. The standard Grizzly models had a 5.5" slide, most often seen fitted with a 6.5" barrel which extends one inch beyond the slide, and less commonly with a 5.5" barrel in combination with a factory fitted bushing style recoil compensator. Special models with 8" and 10" barrels for hunting and silhouette competition were also produced (in small quantities). A Grizzly caliber conversion kit typically included a barrel, a magazine, an ejector, an extractor, a barrel bushing, and a recoil spring. Some also included a bushing type recoil compensator and a wrench for use with the compensator. The standard recoil spring used in the Mark I and II pistols has a 27lb rating, compared to the 16lb rating for a standard 1911 pistol chambered for 45acp. 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「LAR Grizzly Win Mag」の詳細全文を読む スポンサード リンク
