  Detailed Features 
  The blued finish looks good and gives reasonable corrosion resistance. At 5 inches, the barrel balances handling and accuracy well enough for range work and home defense. 
   
  Single-action means you cock the hammer manually before each shot. That's the nature of the design, and it's part of why trigger pull feels clean and deliberate. 
   
  The walnut grip is a one-piece design that sits comfortably in hand during extended sessions.

Owners of the Cimarron NO. 3 1st American .45 Colt tend to focus on its historical connection to Old West revolvers and its visual appeal. Craftsmanship and material quality come up often, generally in positive terms.

Shooting performance is widely considered solid. The .45 Colt cartridge is appreciated for manageable recoil at cowboy action events and target sessions. Weight and overall size generate some debate: some shooters like the heft, others find it a bit much for extended carry. Price draws occasional comment, with opinion split between those who consider it fair for the quality and those who compare it unfavorably to cheaper modern alternatives.

Collectors and cowboy action shooters tend to be the most enthusiastic; people looking for a purely practical defensive revolver are more divided.
