How do you tell a square butt revolver from a round butt revolver?

To distinguish a square butt revolver from a round butt revolver, examine the grip frame's shape. A square butt revolver features a more angular, flat grip that allows for a larger grip area, while a round butt revolver has a smoother, rounded grip that tapers towards the bottom. This difference can affect handling and comfort, particularly when using different types of grips or holsters. Additionally, the model designation often indicates the grip style, providing another clue.
