The Colt Single Action Army Revolver in .45 Colt with a 5.5-inch barrel is the middle barrel length of the three standard SAA configurations. The color case hardened frame paired with a blued barrel is the traditional two-tone finish associated with the original 19th-century design.

Detailed Features 

The spurred hammer is easy to thumb back for deliberate shot placement. Fixed sights keep the profile clean and the design faithful to the original. Carbon steel construction throughout. The Double Eagle Black Composite grip provides a secure hold. 
 
The 5.5-inch barrel sits between the 4.75-inch Artillery model and the 7.5-inch Cavalry model, offering a reasonable balance between muzzle velocity and overall length. The blued finish on the barrel and cylinder contrasts with the case hardening on the frame.

The 5.5-inch Colt Peacemaker sits in the middle of the barrel length options and attracts a mix of collectors and cowboy action shooters. Most owners are happy with it, though the barrel length rarely gets called out specifically -- people tend to have stronger opinions about the 4.75-inch and 7.5-inch variants.

Consistency and reliability are the most common compliments. Owners describe accurate, repeatable performance at typical handgun distances and note the single-action trigger is crisp once you get used to cocking before each shot.

Nostalgia plays a real role in why people buy this revolver, and that comes through in the reviews. Owners mention range trips that turn into storytelling sessions, or using it alongside period-correct holsters and rigs.

The weight (42 oz) and cost both come up as considerations. The weight is not a problem for range use but limits practical carry appeal. The price is what it is for a Colt factory SAA, and most buyers go in knowing that. Maintenance requirements are standard for a blued revolver -- keep it oiled, wipe it down after handling.
