Among Colt Single Army Action revolvers, certain variations stand clear as collecting classics whether through design, history or both.

The epic tale of the Single Action Army from its introduction in 1873 through three generations of production make it one of the most important firearms ever made. In an event that draws from seven amazing collections amassed through 250 years of collecting experience, Rock Island Auction will offer some of the finest and rarest Colt Single Action Army revolvers for sale in its Dec. 6-8 Premier Auction in Bedford, Texas. Here are some of the best.

An excellent Colt first generation Single Action Army revolver is accompanied by its original box and a factory letter.

Single Action Army: Pinched Frame

The name of this collecting rarity is a bit deceiving in that the frame isn’t pinched, but rather the pinched sighting groove found on extremely early production of the Single Action Army. The rear sight is located forward of the standard frame position at the extreme rear of the top strap. While it was discontinued on the Single Action Army, the pinched frame  remained a feature on the Cloverleaf and House revolvers being produced at the same time.

The pinched frame is only known on the civilian SAAs with serial numbers below 200 manufactured before mid-July 1873. How many have survived is unknown. J.R. Edie, Captain of Ordnance at Springfield Arsenal wrote to his boss in Washington, D.C., on July 22, 1873, “The change in the sight is slight but is quite an improvement.” The full grooved top strap became standard on the Army contract of July 23, 1873.

This revolver, serial number 122, has been described by Colt historian and author Ron Graham as “the finest known, .45 Colt caliber, private collection, pinched frame Single Action that retains its first assembly factory original condition.” The revolver is accompanied by a nearly impossible to find nickel-plated brass skeleton stock. The revolver and stock are pictured and identified in Graham, John Kopec and C. Kenneth Moore’s “A Study of the Colt Single Action Army Revolver” on page 12 where it is described as “Unquestionably one of the finest pre-Gov’t Contract SAs. Documented evidence of Colt’s skeletonized stock production exists for early 1874. This revolver-stock combination is physical evidence of probable earlier production.”

Single Action Army: Cavalry Model

The Cavalry Models of the Colt Single Action Army are martially-approved revolvers with 7 1/2-inch barrels chambered in .45 Colt manufactured between 1873 and 1892. There were 12,500 made under contracts with the United States government. The lowest known serial number for a Cavalry Model is 179. Rock Island Auction sold the SAA with the third lowest known serial number, no. 189, in May 2021.

The Cavalry Model is ripe with sub-genres of Single Action Army collection, whether they are marked by the various sub-inspectors, like Orville W. Ainsworth who inspected the earliest Cavalry Colts or those that followed like Henry Nettleton, David F. Clark or Rinaldo Carr, or where and when they were issued, like Lot 5 revolvers of the ill-fated 7th Cavalry led by George Armstrong Custer at the Little Bighorn.

This high-condition Colt Cavalry Model SAA was manufactured in 1884 and sub-inspected by David F. Clark. It has received a gold seal letter from Colt expert John Kopec who believes the revolver is in “as new” because it was issued to a state militia where it remained in storage until it was returned to Springfield Armory. The gun’s factory applied military blue finish remains in almost complete coverage.

Nickel-plated Cavalry Models are another sub-genre to explore. Sub-inspected revolvers left the factory with the “government blue” finish, yet there are numerous examples and a handful of theories as to how they received their nickel plating, ranging from being issued to Native American scouts, special orders for officers, surplus revolvers bought back by Colt and being issued to the U.S. Navy.

Martially condemned parts that made it to the civilian market and guns that were part of an overrun are also areas of collecting Cavalry Model areas worth investigating. As the authors of “A Study of the Colt Single Action Army Revolver” wrote, “The reader should be reminded that in nearly every instance where a revolver is encountered with strange characteristics, these characteristics in turn will “tell a story” and much knowledge may be learned by careful examination and reconstruction of the events which lead to certain Ordnance marks which were, or were not applied to any specific Colt Single Action revolver.”

This Cavalry Model was manufactured in 1880 and inspected by sub-inspector David F. Clark. According to Colt expert Kopec it was likely a state militia revolver that along with other surplus revolvers were sold on the civilian market. Kopec calls it a “very fine condition early 1880s production Cavalry model.” The revolver has a military blue finish and one-piece walnut grip and has Clark’s and Ordnance Inspector Lt. David A. Lyle’s inspection stamps.

Colt Single Action Army: Rimfire Chamberings

Colt Single Action revolvers chambered for rimfire cartridges are extremely rare, either in .22, .32 and .44 calibers, with .22 being most common. In 1888, Colt had about 100 unsold .44 rimfire SAAs with standard frames and were converted to plinkers by replacing them with .22 caliber barrels and cylinders. Despite already being stamped .44 cal on the trigger guard, 107 revolvers were overstamped for .22 caliber.  The company made 93 .22 rimfire target pistols with flattop frames.

This Colt Single Action Army is chambered in .22 Rimfire with a flattop frame for target shooting. It has adjustable front and rear sights. Colt made 96 SAAs chambered for .22 Rimfire on flattop frames with a smaller striker on the hammer.

Rarer than the .22 Rimfire SAAs are the .32 Rimfire, of which only two were made. One is a standard frame, while the second, with a flattop frame, was a special order. Colt made 1,863 of the Single Action Army in .44 rimfire, not including a pilot model. Of the pistols made for .44 Rimfire, 107 were converted to the .22 Rimfire.

This Colt Single Action Army for sale was originally made in .44 Rimfire before being converted with different barrel and cylinder for .22 Rimfire cartridges. The company converted 107 revolvers from .44 Rimfire to .22 Rimfire.

Single Action Army: Target Models

Target pistol shooting came into popularity in the late 1880s, especially in England after the National Rifle Association opened up the Wimbledon Commons and the shooting matches held there for pistol shooters.  Shooting quickly became the British national pastime.

In 1890, marksmen would claim most of the prizes in England and across Europe. That year also marked the opening of the new shooting range at Bisley. Colt won 14 of 16 prizes in the first series of matches and Walter Winans, an internationally recognized shooter, won the first year at Bisley firing a Colt 1878, but double action revolvers weren’t the best for accuracy and target shooting because its trigger couldn’t be adjusted.

Colt advertised its Single Action Army for target shooting in a number of chamberings including .32 Colt, .32 S&W, .23-44, .38-44, .44 Russian and .44 Special. The company introduced its flattop frame for mounting adjustable rear sights in 1888 and ultimately offered it in 22 different calibers including British calibers.

Of the flattop frame, a Colt advertisement stated “the frame has a flat top instead of the half-round top through which is a lateral sliding bar rear wind-gauge sight which is capable of fine adjustment. The front sight is arranged by a base attached to the barrel into which are fitted fine pin-head sights. Several sights of different heights are provided which enable the marksmen to use various loads from the light gallery charge up to the full charge.”

This Colt Single Action Army flattop is chambered in .44 Smith & Wesson with extra-long grips and a 7 1/2-inch barrel. It is one of only about 925 flattop target SAA revolvers and one of only 106 in .44 Smith & Wesson and one of 80 with the barrel length, chambering and blued finish. It was shipped to Major Charles H. Gans of New York who was an award-winning marksman who won the 1,000 yard match for the Wimbledon Cup in both 1880 and 1890.

A report from 1890 about Colt’s target shooting success read, “It will be noticed that the Colt revolvers are leading all others. This is a dismal year for the Webleys. Not only has the Colt won all prizes in the Officer’s revolver matches at Bisley, but it also carried off all but the smallest prize at Dublin, and at Edinburgh Midlothian Rifle Association revolver competitions took all, without exception. It is now, by all fair-minded men over here, conceded to be ahead of any English revolver.”

This Colt Bisley Single Action Army flattop model was manufactured in 1900 chambered for .32 Colt, a target shooting cartridge, and has a 7 1/2-inch barrel. It was shipped to Caverhill and Learmont in Montreal Canada on Jan. 11, 1901. Fewer than 1,000 Bisley revolvers were made with the flattop frame. This revolver is one of only 44 Bisley target model revolvers chambered in .32 Colt. The revolver is illustrated and described on page 136 of "A Study of the Colt Single Action Army Revolver” by Graham, Kopec and Moore.

Colt named a specially made target SAA revolver its Bisley model after the British competition shooting range when it went on the market in 1896. The grips were larger with a sharper drop so the hand could sit deeper in the hand so the gun doesn’t rock back under recoil. The trigger was set back and more curved as well as widened. The hammer was lower and flatter and the revolver came offered in English calibers like the .455 Eley and .455 Enfield. Production of the Bisley model ended in 1912.

This Colt Single Action Army Bisley flattop target Frontier Six Shooter is one of only 78 Bisley revolvers chambered in .44-40 WCF of 976 Bisley flattop revolvers made.

Single Action Army: Sheriff Model

The first Sheriff Model, or “storekeeper’s model,” shipped in 1882, recognizable by not having an ejector rod assembly and generally, a 4-inch or shorter barrel. Fifty-one percent of the Sheriff Models shipped had 4-inch barrels while one-third shipped with 3 1/2-inch barrels. The vast majority of the Sheriff Model were chambered in .45 Colt or .44-40 WCF though later calibers were added. The guns were easily concealable and frequently served as a secondary arm for law enforcement, earning their nickname.

Colt advertised the ejectorless Single Action Army for sale with short barrels for 10 years, from 1888 to 1898, though a survey by Kopec, Graham and Moore recording Sheriff Model revolvers spans 45 years, from 1882 to 1927. About 1,000 to 1,200 were estimated to have been manufactured, but at least one survey puts the number produced at fewer than 600.

Improvements to ammunition, from black powder to smokeless and better primers, made smaller calibers like the .38 and .32 caliber more capable with smaller double action revolvers, and then in the early 20th century small semi-automatic pistols were the final nail in the Sheriff Model’s coffin. After 1909, production was one order, one revolver until 1927.

The revolver below was owned by Texas Ranger Benjamin F. Finn who joined when he was 15 in 1879, serving in Capt. George W. Baylor’s A Company of the Frontier Battalion until he was discharged in February 1882. He won the gun after Baylor took it off a desperado, according to a notarized statement by Finn’s widow.

This Colt Single Action Army Sheriff Model dating from 1882 is extremely rare, shown as soft shipped from the factory to L.D. Nimschke for engraving. Rock Island Auction records reveal the company hasn’t sold a Nimschke-engraved sheriff model and R.L. Wilson only notes one other in “The Colt Engraving Book Vol. 1.” The revolver has stunning scroll engraving through with beaded backgrounds while wavy lines form borders with ornate fan designs on the recoil shield and loading gate and backstrap.

Some Sheriff Models had “fluted frames” that is an early production feature of the ejectorless revolvers. The fluted areas on either side near the cylinder pin were for the clearance of the ejection rod, unnecessary on ejectorless revolvers.

At top, this Colt Single Action Army Sheriff Model made in 1883 has a 2 1/2-inch barrel. In “The Official Record of the Colt Single Action Army Revolver 1873-1895,” by Don and Carol Wilkerson, they note only six non-engraved, blued 2 1/2-inch bare Sheriff Models were made in .45 Colt like this one. Below is a Colt Sheriff Model 1879 with an extremely rare 2 1/2-inch barrel and pearl grips chambered in .45 Colt that is also available in the December Premier.
