About This Firearm
The Colt Single Action Army is a traditional single-action .45 Colt built for cowboy action competition and collecting. Colt still lists it, at an MSRP of $2,299, and this is the factory gun that the Italian copies and Ruger's single actions were drawn from. The frame is color case hardened, the barrel and cylinder are blued, and the cylinder holds 6 rounds.
The hammer's half-cock notch is the whole safety arrangement. There is no transfer bar, so with the hammer down the firing pin sits against the primer of a loaded chamber, and the revolver is loaded with five and the hammer dropped on the empty one. The top strap has no optic provision. The grips are black composite with the Colt eagle, so walnut or imitation ivory panels are a separate purchase.
If you're cross-shopping, the Uberti 1873 Cattleman El Patron copies the same pattern in Italy at an MSRP of $679, weighs 36.8 oz on a 4.75-inch barrel, and arrives hand-tuned with larger sights. The Ruger New Vaquero has an MSRP of $1,099, weighs 40 oz, and its transfer bar lets all six chambers be loaded. Neither one carries Colt's rollmark, and the secondhand market prices that difference.

Strengths & Limitations
- The loading gate and ejector rod let you top off a single chamber without swinging out a cylinder.
- Every 1873 copy is cut to the same grip frame and outside dimensions, so grips and leather made for the pattern fit.
- No alloy anywhere in the pressure path, and the case colors are on the frame alone, so a scratched barrel can be reblued without touching them.
- A reload means thumbing the hammer to half cock, opening the gate and punching out cases one at a time.
- The rear notch is milled into the top strap, so point of impact is whatever Colt regulated and it moves with bullet weight.
- Nothing on the revolver adjusts, including the trigger, so a lighter pull means a gunsmith.

Frequently Asked Questions
What does the half-cock position do?
It frees the cylinder to turn so chambers can be loaded and emptied through the gate, and it is the position Colt points to as the gun's safety feature.
Will it chamber .45 ACP?
No. Colt lists the gun for .45 Colt and catalogs no spare cylinder for it, and .45 ACP has no rim to hold it at the right depth in a .45 Colt chamber.
What .45 Colt ammunition suits it?
Standard factory .45 Colt. The heavy loads marked for large-frame Ruger single actions run above that pressure and are built for a different gun.
