Description
Sam Colt never got around to building this one, but plenty of folks think he should have. The Cimarron MP419 Revolving Carbine takes the familiar frontier single-action revolver and marries it to a walnut shoulder stock and 18 inch round barrel, creating a six-shot carbine chambered in .45 Colt. Fans of classic Westerns will recognize the style right away. Revolving carbines like this one showed up in the Man With No Name films of the 1960s and in the hands of the Man Burner in Lonesome Dove, so it carries a screen legacy all its own even though this cartridge version never rode the real frontier.
Built Like a Peacemaker, Handles Like a Rifle
Everything about the MP419 will feel familiar if you have ever run a single-action revolver. The cylinder holds six rounds of .45 Colt, the hammer cocks for every shot, and the distinctive spur trigger guard keeps the profile period correct. The color case hardened receiver plays off the standard blue barrel and cylinder beautifully, and the one-piece walnut stock finishes it off with a brass butt plate. A blade front sight and notched rear keep the sighting setup simple and true to the era. At just over 39 inches overall, it shoulders quickly and swings easily.
Where the Cimarron Revolving Carbine Earns Its Keep
This carbine has become a go-to pick for Cowboy Mounted Shooters competing in rifle-class events, where its compact length and revolver-style manual of arms are a natural fit. Off the horse, it makes a fun range gun and a standout piece for Western reenactors and collectors who appreciate something a little different from the usual lever gun. The .45 Colt chambering pairs nicely with soft-shooting cowboy loads, so a full afternoon of plinking stays easy on the shoulder. If your safe already holds a Peacemaker or two, this is the natural next addition.

Frequently Asked Questions
How does the Cimarron MP419 Revolving Carbine load and fire?
It runs just like a classic single-action revolver. You load and unload one round at a time through the loading gate, and the hammer must be manually cocked before each shot. If you already shoot a Peacemaker-style sixgun, the manual of arms will feel like second nature.
Is the Cimarron Revolving Carbine legal-class rifle competition ready for Cowboy Mounted Shooting?
This carbine is a popular pick with Cowboy Mounted Shooters running rifle-class events. Its 18 inch barrel, compact overall length, and revolver-style action make it quick to handle from the saddle. Always check your specific sanctioning body's equipment rules before match day.
Can I shoot .45 ACP or other cartridges in this carbine?
No, this version is chambered strictly for .45 Colt, also called .45 Long Colt. Cimarron does offer the Revolving Carbine in other chamberings like .44-40 and .38 Special/.357 Magnum, but those are separate models. Stick with quality .45 Colt ammunition in this one, and cowboy action loads make for an especially pleasant shooting session.
What kind of sights come on the MP419?
It wears a simple, period-correct setup with a blade front sight and a notched rear. There are no provisions for optics, which keeps the carbine true to its Old West styling. For the short to medium ranges this gun was made for, the fixed sights get the job done just fine.
