#Colt saa 45 serial number
Contrary to popular belief, the Mason patented spring-loaded, cylinder-pin release catch first appeared in 1896 around serial number 164,000, which were still “black powder” guns. In 1898, Colt made the necessary changes to permit its guns to be used with smokeless powders however, it wasn’t until 1900 (revolvers with serial number 192,000 or higher) that Colt began to officially warrant its guns for such. 45 Colt was soon loaded with smokeless powders with loads eventually standardized with 250- and 255-grain lead hollowbase bullets from Remington and Winchester, respectively, at around 870 fps, but today are listed at 860 fps. That charge was increased to 38 grains by 1898. 45 Colts include a (1) Model 25-5 with 83⁄8-inch barrel, (2) Model 25-5 with 6-inch barrel, (3) Model 25-5 with 4-inch barrel and a (4) Model 625-6 Mountain Gun with a tapered 4-inch barrel. Incidentally, the U.S Cartridge Company first listed a 255-grain bullet with 35 grains of black in 1882, but 45 Colt had such a stellar reputation as a “man stopper” and for its effectiveness on game. I have tested vintage loads that produced an honest 1,000 fps. However, the first known commercial listing is found in the 1880 UMC catalog. 45 Colt factory load containing 250-grain bullets propelled by 40 grains of black powder was first offered is unknown, but it was probably assembled at the Colt factory. Nonetheless, the 30-grain charge with a 250-grain bullet reached around 850 fps from a 7.5-inch barrel. (In fairness, many historians maintain that original loads contained 40 grains of black powder with 255-grain bullets, including noted Colt authority John Kopec.) With multiple powder charge weights there has been considerable confusion on this subject. The revolver and ammunition were officially adopted for service in 1873.Ĭontrary to what has been traditionally published, records indicate that early loads from Frankford Arsenal contained a copper case loaded with a 250-grain, roundnose flatpoint lead bullet pushed with 30 grains of black powder, with additional charge weights soon added. 45 Colt was a joint development between Colt’s Patent Firearms Manufacturing Company and Union Metallic Cartridge Company. While there were multiple experiments with different cartridges, the.

Army in 1872 and would become known as the Colt Single Action Army, Model of 1873, Peacemaker, Model P, “Thumb Buster” and a host of other affectionate names. 45 Colt’s origins started in 1871 when Colt began designing a new sixgun specifically to house metallic cartridges. They include a (1) restored 1900 revolver with carved grips, (2) 1903 custom engraved, (3) 1901 with carved pearl grips, (4) 1899 with carved grips, (5) 1957-era custom, (6) custom 1901 with stag grips, (7) 1903 with custom carved grips and a (8) Colt New Frontier SAA with custom carved grips. Most of these are custom, tuned and have accounted for several head of big game. 45 Colt with a 4.75-inch barrel ranks as one of Brian’s favorite handgun configurations.
