GWM: The Grizzly Winchester Magnum
Formed in West Jordan, Utah in 1968, L.A.R. busied itself with bolt action rifles and upper receiver assemblies for AR-15 style carbines until SHOT Show 1983, when they appeared in Dallas with eight different caliber conversion units for M1911 pistols, and a gun they tentatively called the Grizzly Winchester Magnum, or GWM. Designed by L.A.R. owner Heinz Augat and Perry Arnett, who held accurizing patents for M1911 style handguns, the Grizzly was something special.
Like 6.5-inch extended barrel, .45 Winchester Magnum kinda special.
