The Remington Model 10 and Model 10A are both shotguns, but they differ primarily in their design and features. The Model 10, introduced in 1908, is a pump-action shotgun known for its robust construction and reliability. The Model 10A, introduced later, featured modifications such as an improved action and refinements to the overall design for better performance. These changes made the 10A more user-friendly and efficient, catering to evolving shooter needs.
