Three guns at 10 paces Part 2 Part 1
How important is barrel length?
By Dennis Adler
Although Colt’s offered many barrel lengths, the company only considered the 1888 Sheriff’s Model with 3-1/2 inch barrel, the 4-3/4 inch, 5-1/2 inch and 7-1/2 inch barrel lengths as “standard” models, everything else was a special order barrel. The 5-1/2 inch and 4-3/4 inch were introduced in 1875, technically, three years after the 7-1/2 inch model designed by William Mason was accepted by the U.S. Ordnance Department as the Army’s new military issue sidearm. That was in 1872 not 1873. While the Peacemaker is regarded as an 1873 model, the first patent was granted on September 19, 1871. A second patent was received on July 2, 1872 and both patent dates were stamped on the left side of Singe Action Army frames produced through 1875. That year Mason and Colt’s were granted a third patent for the design dated January 19, 1875. All three patent dates were stamped on frames beginning early that year. This was known as the three line patent date stamp and 5-1/2 inch models have three patent dates on their frames.
