The Grizzly Win Mag ® line of semi-automatic pistols were manufactured by L.A.R. Manufacturing, Inc. from 1983 to 1999. I know of four production models: the Mark I, Mark II, Mark IV, and Mark V, which were chambered in .45 Win Mag, .45 Win Mag, .44 Magnum, and .50 AE, respectively. The Mark I was also available in many convertible calibers, including .45 ACP, 10mm Auto, 9mm Win Mag, .357 Magnum, and 357/44 GWM, and shared a 37/49 parts commonality with a standard M1911A1. At the time of their introduction, they were the most powerful production handguns in the world.
