The Cimarron P-Model Dual Cylinder in .45 Colt/.45 ACP (MPN MP437) is a single-action revolver that ships with an extra .45 ACP cylinder, letting shooters switch between the classic .45 Colt and widely available .45 ACP without buying a second revolver. Cimarron Firearms builds this revolver on a case-hardened Pre-War-style frame, finishes the 5.5-inch barrel in standard blue, and fits a one-piece walnut grip. The 6-round cylinder chambers each caliber depending on which cylinder is installed. Among Old West reproductions in the revolvers category, the P-Model Dual Cylinder favors shooters who want caliber flexibility in a classic single-action package.

Key Specifications

• Chambers both .45 Colt and .45 ACP via an included extra cylinder.
• Built on a case-hardened Pre-War-style single-action frame.
• Features a 5.5-inch blued barrel.
• Fitted with a one-piece walnut grip and holds 6 rounds.
• The sights are fixed.
• Overall length measures 14.2 inches.
• Like other modern-production single-action reproductions, the firing pin is a separate spring-loaded part mounted in the frame rather than fixed to the hammer, letting every chamber be loaded safely instead of requiring an empty chamber under the hammer as with an original period design.
• Loads and unloads one round at a time through a loading gate on the right side of the frame, with a spring-loaded ejector rod for pushing out spent cases.
• As a traditional single-action design, the hammer must be manually cocked before every shot.
• The cylinder is removed for cleaning by opening the loading gate, half-cocking the hammer, and withdrawing the spring-retained cylinder base pin, a simple owner-level takedown.
