The 'Thunderer was designed in 1990 by Cimarron founder and president Texas Jack Harvey and is produced only by A. Uberti exclusively for Cimarron Firearms Co. - To paraphrase the famed film director John Ford If this isn't the way the old west six guns were it's the way they should have been!' Firearms buffs have often wondered why the single action was never produced in the 19th century with the grips of the double-action Thunderer revolvers. Now you can have the best of both worlds in four handsome and practical barrel lengths. The compact 3 1/2-incher is a superb carry single-action. This mating of two popular frontier six-shooters has given birth to one of today's most sought after single action wheel guns!-Phil Spangenberger - Specifications and Features: - Caliber: .45 LC - Barrel: 3 1/2 - Weight: 2.37 lbs - Frame: Case Hardened - Grip: 1 Piece Walnut Smooth Grip - Finish: Stainless - Sights: Fixed
