According to Colt, it was designed to shoot 2' groups at 15 yards, and it does, even 44 years later. We recently had a visitor looking for the date of manufacture (DOM) of his Colt Python with a low serial number beginning with the KT prefix. He called Colt at 1-800-962-COLT and they informed him that the DOM was 1991. Thanks Ken, for letting. Enter the serial number, without spaces or dashes, to search the database. If multiple models appear for your serial number simply match the date with the appropriate model, as certain vintage firearms can share serial numbers between different models. Aug 02, 2020 I’m not sure if my Colt SP1 serial number 0791X ( no SP prefix ) is completely correct. Everything seem correct but the safety doesn’t have the hole on the right side., 11:29 AM #13.

The Colt Single Action Army (also known as the Model P, Peacemaker, M1873, Single Action Army, SAA, ) is a single action revolver with a revolving cylinder holding six metallic cartridges. It was designed for the U.S. government service revolver trials of 1873 by Colt's Patent Firearms Manufacturing Company, today Colt’s Manufacturing Company, and adopted as the standard military service revolver until 1892.
Razer tartarus chroma profiles. It is perhaps the most copied, fraudulently modified to replicate an original Colt SAA, than any other revolver made.
The Colt Single Action Army has been offered in over 30 different calibers and various barrel lengths. Its overall appearance has remained consistent since 1873. Colt has discontinued its production twice, but brought it back due to popular demand. The revolver was popular with ranchers, lawmen, and outlaws alike, but current models are mostly bought by collectors, shooters participating in Cowboy Action Shooting and re-enactors. Its design has influenced the production of numerous other models from other companies.
Bound by the Rollin White patent (#12,648, April 3, 1855) and not wanting to pay a royalty fee to Smith & Wesson, Colt could not begin development of bored-through revolver cylinders for metallic cartridge use until April 4, 1869. The Colt Single Action Army was designed for the United States government service revolver trials of 1873 by Colt's Patent Firearms Manufacturing Company and adopted as the standard military service revolver. Its original moniker was the 'New Model Army Metallic Cartridge Revolving Pistol'.
The very first production Single Action Army, serial number 1, thought lost for many years after its production was found in a barn in Nashua, New Hampshire in the early 1900s.
The .45 Colt cartridge was of center fire design containing charges of up to 40 grains (2.6 g) of fine grained black powder and a 255-grain (16.5 g) blunt round nosed bullet. Relative to period cartridges and most later handgun rounds, it was quite powerful in its full loading.
The Colt Single Action Army revolver (along with the 1870 and 1875 Smith and Wesson Model 3 ('Schofield') revolvers replaced the Colt 1860 Army Percussion revolver. The Colt quickly gained favor over the S&W and remained the primary US military sidearm until 1892 when it was replaced by the .38 Long Colt caliber Colt Model 1892, a double action revolver with swing-out cylinder. By the end of 1874, serial no. 16,000 was reached; 12,500 Colt Single Action Army revolvers chambered for the .45 Colt cartridge had entered service and the remaining revolvers were sold in the civil market.

Variations 1873–1941
Colt SAA Flattop Target
The Single Action Army became available in standard barrel lengths of 4¾', 5½' as well as the Cavalry standard, original 7½'. The shorter barreled revolvers are sometimes called the 'Civilian' or 'Gunfighter' model (4¾') and the Artillery Model (5½'). There was also a variant with a sub 4' barrel, without an ejector rod unofficially referred to as the 'Sheriff's Model', 'Banker's Special', or 'Storekeeper.
From 1875 until 1880 Colt marketed a Single Action revolver in the .44 rimfire Henry caliber in a separate number range from no. 1 to 1,863.
A 'Flattop Target Model' was listed in Colt's catalogs from 1890 to 1898. Colt manufactured 914 of these revolvers with a frame which was flat on the top and fitted with an adjustable leaf rear sight. The front sight consisted of a base with an interchangeable blade.
In 1896, at serial number 164,100, a spring loaded base pin latch replaced the cylinder pin retaining screw and by 1900, at serial number 192,000, the Colt Single Action was certified for use with smokeless powder. In 1920, larger, highly visible sights replaced the original thin blade and notch. The revolvers remained essentially unchanged from that point until cessation of manufacture at the beginning of World War I.
45 Colt Cartridge variations
Colt .45 Cartridges
The first Colt Single Action Army revolvers were manufactured in .44 American caliber for the 1872 government trials, as the .44 American was the cartridge used in the 1000 Smith & Wesson Model 3 revolvers issued to the troops. After the tests, the Colt was declared the superior revolver and the government specified that a .45 caliber cartridge would be required. With the adoption of the Colt Single Action Army revolver in 1873, the service cartridges were Copper cased .45 center fire Benét inside primed “Colt’s Revolver Cartridges” loaded with 30 grains of black powder and an inside lubricated bullet of 250 grain. They were manufactured Frankford Arsenal, Philadelphia, PA, through 1874. In 1875, the cartridge was shortened so that it would also function in the newly adopted S & W Schofield revolver. It was designated “Revolver Cartridge” and loaded with 28 grains of black powder and a bullet of 230 grain. The Benét primed cartridges were manufactured until 1882 and then replaced by reloadable cartridges with brass cases and external primers.
The original .45 Colt black powder load of 40 grains propelled the 250-255 grain bullet at a nominal 970 feet per second (300 m/s). Authors John Taffin and Mike Venturino have demonstrated that modern black powder loadings of the 45 Colt cartridge frequently achieve velocities in the vicinity of 1,000 feet per second (300 m/s) with the 7½' 'cavalry' barrel length, even though modern solid-head cases make it impossible to load a full 40 grains. Specifications for 20th-century smokeless loads set velocity with a 255-grain (16.5 g) round-nosed flat-point bullet at 870 feet per second (270 m/s) providing 429-foot-pound-force (582 J) energy.
The current version of the 45 Colt differs from the original cartridge case in that the rim is significantly larger (with a groove immediately above it) and the internal aspect of the primer pocket is surrounded by solid brass instead of protruding into the powder chamber. This 'solid head' case is stronger and resists deformation of the primer pocket. Some commercial and custom revolvers and single-shot pistols (such as the Ruger Blackhawk, T/C Contender and others) employ high-pressure loads that are dangerous in the Single Action Army and other vintage arms chambered for the 45 Colt cartridge, especially 19th-century 'pre-smokeless' revolvers which should be fired (if at all) only with black powder or light smokeless loads.
Prior to World War II, the 45 Colt used a groove diameter of .454'; post-WW II production adopted the .452' groove diameter of the 45 ACP. Handloaders should slug their barrels to determine the correct groove diameter, and size cast bullets accordingly.

Calibers
By 1878 the Colt SAA was being offered from the factory in additional calibers for civilian and foreign military sales. Many were sold in .44-40 Winchester Center Fire (44WCF), introduced in 1878 to allow cross-compatibility with the Winchester '73 lever action rifle; this model was called the 'Colt Frontier Six-Shooter' which was etched and later roll-stamped on the left side of the barrel. Additional period calibers for the SAA included .38-40 Winchester (38 WCF) introduced in 1884, the .32-20 Winchester (32 WCF) introduced in 1884, the .41 Colt introduced in 1885, the .38 Long Colt in 1887, the .38 Special and the .357 Magnum in the 20th Century. Some of the separately-serialized .44 Henry rimfire revolvers were rechambered to .22 rimfire after 1885. The SAA at one time or another was offered in dozens of calibers from .22 rimfire to.476 Eley, though the .45 Colt has always been the most common. A scaled-down .22 rimfire version called the Scout or Frontier Scout was available in the late 20th Century.
1st -, 2nd -, 3rd -Generation Colt Single Action and Calibers
From 1873 through 1940 (with small numbers assembled during and after World War II, the so called 'Pre-War, Post-War' model), production of the Colt Single Action Army reached 357,859. This is identified as the 'Pre War' or 'First Generation' of the model. Calibers, at least thirty in all, ranged from .22 rimfire through .476 Eley, with approximately half, or 158,884 (including Bisley and Flat Top Target variations), chambered for .45 Colt. The next most prevalent were the .44-40 Winchester Center fire (WCF) at 71,392; 38-40 (38 WCF) at 50,520; 32-20 Winchester (32 WCF) at 43,284 and, the 41 Colt at 19,676.
Second Generation Colt Single Action Army revolvers were produced from 1956–1974 and carried serial numbers in the range of 0001SA to 73,205SA. About 400 of the Second Generation Colt Single Actions were factory engraved by Colt's, the factory engravers of the period were Alvin Herbert, Earl Bieu, Dennis Kies, Robert Burt and Leonard Francolini. One of the most sought-after engravers who have worked on Colt revolvers was Alvin White and the shop of A. A. White Engravers.
The Third Generation began in 1976 characterized by a change in barrel thread pitch and a solid cylinder bushing replacing the removable/replaceable part from the first and second generations. This Generation ran until 1982 as a limited-issue product with the serial number range of SA80,000 to SA99,999. In 1994, production resumed with the increase in popularity of 'Cowboy Action Shooting'. These models are known either as 'Late Third Generation' or sometimes Fourth Generation with the serial number convention changing yet again starting with S02001A and continuing with the 'S' prefix and 'A' suffix to 2009. Colt currently offers the Single Action Army in one of two finishes: either an all-nickel or blued with color case-hardened frame; in the traditional three barrel lengths: 4¾', 5½' and 7½'; and six chamberings: 32-20, 38-40, 44-40, .38 Special, 357 Magnum or 45 Colt; a total of 36 variations.

It has been argued that having a Engraved Colt not done by the factory diminishes the value of the Colt Revolver. In a sense that may be true to those who collect only Factory Engraved and Factory Lettered Colts. However many firearms are sent outside or ordered in the white by distinguished master engravers for finishing work to specific customer demands.

I've looked around for this information before and had no luck finding anything useful. Maybe I've overlooked it.
What I'd like to know is what the serial number ranges are for the various Colt companies. That, and what years Colt kept the names of various companies.
Originally, Colt SP1's were made by Colt's Patent Firearms Mfg Co. The two I have are in the 35XXX range and one my friend has is in the 66XXX range. I've seen them all the way back to the 2XXX range with this same company marking.
Sometime later Colt SP1's were made by Colt's Firearms Division. These seem by far to be the most common markings on SP1's. It is common to see serial numbers on these in the 80XXX to 180XXX range. I'd really like to know the year of this transition.
Most, if not all, of the AR15A2 Sporter II's were made by Colt's Firearm's Division and the serial number range seems to be in the low to mid 300XXX range. These were most popular in the mid to late 80's.
During manufacture of all of these Colt continued to use the SP prefix.
Then, that changed..
Witness the Sporter Blue Label series. These were made by Colt's Mfg Co Inc. and early on some still bore the SP prefix. It appears that those still using slab side SP1 style receivers had the SP prefix while the transitional lowers with the A2 features ie: magazine release fence, built up receiver extension ring, and radiused front takedown pivot lugs, started using different prefixes such as MT for Match Target. All, however, still went under the model name Sporter. This was due to legislation enacted by certain states that banned, by name, the AR15 in the late 80's.
It seems that the latest breed of Colt made civilian rifles is being manufactured under the company name of Colt's Defense.
From Biggerhammer.net I was able to glean some information about the dates of manufacture on the box labels. From earliest to latest:
1963-1966 Plain Box, no label
1966-1968/69 Tan Label (Three Prong Flash Hider)
1970-1984 Tan Label (Birdcage Flash Hider)
1984-1989 Green Label (Beginning of various A2 features)
1989-1990 White Label
1991-Present? Blue Label
None of this points out what company made them though. The serial number list is excellent if you want to know what year your Colt AR15 was made, but again, it doesn't tell you which company made it.

So, what years did Colt operate under Colt's Patent Firearms Mfg Co, Colt's Firearms Division, Colt's Mfg Co Inc, and Colt's Defense? Forgive me if I left one out. They seem to have changed the company name quite a bit and I've found it difficult to keep up with. Thus, the reason I'm hoping to obtain this information for the good of all.
