Colt Single Action Army, 1899 to 1946: what the entry covers
What this entry covers
The entry reads in full "Colt, Single Action Army (Bisley, Standard, and target variations), all original, mfd. from 1899 to 1946, S/N range from 182000 to 357869."1 It sets three conditions: a date of manufacture from 1899 to 1946, a serial number from 182000 to 357869, and original condition1. It names no calibre1.
Neighbouring lines on the same page cover later revolvers. The second generation has its own line: "Colt, Single Action Army (2nd Generation) revolvers, having S/Ns from 0001SA to 82000SA, all cal.s, made between 1956 and 1976."1 The page also lists individual engraved, presentation and commemorative Single Action Army revolvers, such as the Theodore Roosevelt and United States Bicentennial models1. Whether a particular firearm fits this entry depends on the ATF wording above.
Identifying it
The serial number is the first check. In a published Colt serialization table, 1899 production begins at 182000, the same figure that opens ATF's range12. The table notes revolvers built for smokeless powder from 1900, at about 1920002. It shows long-flute cylinders in 1915, the .45 ACP in 1924, the .38 Special in 1930 and the .357 Magnum in 19352.
The upper end needs care. The table's last entry is "A few S.A.A. during and just after the war", numbered 357000 through 3578592. ATF's range runs to 3578691. Mike Venturino's 2018 Handloader article, citing Colt, also gives 357859 as the last first-generation number5. Both published figures end at 357859, ten numbers below ATF's; we have not found an explanation for the difference, so we note it rather than resolve it125.
Bisley models are marked "(BISLEY MODEL)" on the barrel3. Compared with the standard revolver, they have a lower, wider hammer spur, a longer grip, a larger trigger guard and a wider, more curved trigger4. They were numbered in the same sequence as the standard model3.
Common confusions
- Bisleys made before 1899. American Rifleman gives the Bisley serial range as 156300 to 3319163, and the serialization table begins Bisley production at about 154000 in 18942. Bisleys numbered below 182000 fall outside this entry's stated range1.
- When the Bisley ended. Sources differ: the serialization table puts the end in 19122, while both American Rifleman articles give 191534.
- Second-generation revolvers. Revolvers with "SA" serials, starting at 0001SA in 1956, are later production2 and have their own ATF line1. The table marks 1976 serials from 80000SA as the start of a third generation2, while ATF's second-generation line runs to 82000SA1.
History
The table's calibre breakdown counts 310,386 standard, 914 flattop target, 44,350 Bisley and 976 Bisley target revolvers in first-generation production2. The two Bisley figures add up to 45,326, the total that American Rifleman gives for the Bisley3. That article also lists 18 chamberings, from .32-20 to .455 Eley, and 4¾-, 5½- and 7½-inch barrels3. These totals cover production from 1873 on, not only the years in this entry2.
Further reading
- The serialization tables2 give year-by-serial starting points, calibre introductions and a calibre-by-model count.
- American Rifleman's Bisley article3 gives the Bisley's serial range, markings and finishes.
- Wiley Clapp's article4 explains how the Bisley's grip, hammer and trigger differ from the standard revolver.
