After employing the barrel latch patents of Col. George Schofield, Smith & Wesson produced what is probably the best design for a top-break revolver. This gun was used for a few years by the U.S. Army, from 1875 until about 1880, when they were sold off as surplus, most being reworked and sold as "Wells Fargo Models." The cartridge was second only to the .45 Colt, reloading was much faster than single actions from Colt and Remington, and the guns were well made. Only about 800 or so were sold on the commercial market. The Schofield latch was superior to the T-shaped latch of the other No. 3 Models, both in use and wear resistance, probably only a little less durable than the Webley's stirrup latch. Ah, but S&W had to pay Schofield a royalty (of twenty five cents per gun) to Schofield, and, unlike White's agreement, S&W would have to defend its use. So, with the Governemnt contract filled, S&W went back to their old No.3 .44 caliber models. Though the grip profile changed, as did the extractor, all .44 framed guns were designated as No.3 Models.
