Description
The Taurus Deputy 45 Colt is a single-action revolver chambered for the cartridge the pattern was designed around, catalogued as 2-D4551. Six rounds, a 5.50-inch barrel, and a polished black finish across the steel barrel, cylinder and frame.
45 Colt and the single-action revolver arrived together in 1873 and neither has changed much since. It is a low-pressure cartridge throwing a heavy bullet at a modest speed, which is why it recoils with a push rather than a snap and why the Taurus Deputy 45 Colt is far more pleasant to shoot than the bore diameter suggests.
MAG5 Firearms has it in stock. Handguns ship to a licensed FFL on a signed 4473, and we coordinate the transfer with your dealer.
Why the cartridge suits the gun
- 45 Colt runs at low pressure, so recoil arrives as a shove into the hand rather than a jolt into the wrist.
- A heavy bullet at moderate velocity is easy to shoot accurately once the sights are on.
- The plough-handle grip lets the Taurus Deputy 45 Colt roll in the hand under recoil instead of driving straight back.
- Cowboy action loads are mild, widely available and inexpensive, which makes a long range session realistic.
- A 5.50-inch barrel gives the sight radius that makes the single-action trigger worth having.

Handling a single action
- The hammer is cocked by hand for each shot, and the trigger that follows is short and light because the work is already done.
- Loading and unloading happen one chamber at a time through a gate on the right side, with the hammer at half cock.
- A transfer bar safety blocks the firing pin until the trigger is fully pressed, so all six chambers can be loaded.
- That is a real improvement on the 1873 original, which had to be carried with an empty chamber under the hammer.
- The ejector rod pushes empties out individually. There is no swing-out cylinder and no speedloader for the Taurus Deputy 45 Colt.

45 Colt is produced to the dimensional and pressure standards published by SAAMI, and standard-pressure factory ammunition from any reputable maker is appropriate here. One caution worth knowing: some 45 Colt is loaded well above standard pressure for modern large-frame revolvers, and that ammunition does not belong in a single action of this pattern. Stick to standard-pressure and cowboy loads. We stock Remington Performance WheelGun 45 Colt and HSM Cowboy Action 45 Colt.

Why the Deputy earns its place
- The Taurus Deputy 45 Colt is one of the least expensive routes into single-action shooting and cowboy action competition.
- A transfer bar means six loaded chambers, which the original design never allowed.
- 45 Colt is a large-bore cartridge that is genuinely comfortable to shoot in a gun this weight.
- A 5.50-inch barrel and a polished finish make it a pleasant thing to own as well as to shoot.
- Taurus backs it with a limited lifetime repair policy that follows the firearm rather than the original buyer.
This is bought for enjoyment rather than necessity, and there is nothing wrong with that. The Taurus Deputy 45 Colt suits anyone drawn to cowboy action shooting, to the history of the pattern, or to a slower and more deliberate way of shooting than a modern semi-automatic allows. It also serves perfectly well as a trail or property revolver where six rounds of 45 Colt cover the job.
