What are the key features of the Smith & Wesson 5904?
The Smith & Wesson 5904 is part of the venerable 3rd Generation series, known for its robust construction and reliability. This 9mm police trade-in pistol features an aluminum alloy frame, which helps keep the weight down compared to its all-steel 5906 counterpart, making it a bit more comfortable for extended carry or range sessions. The blued steel slide provides a classic look and durability. It operates in a traditional double-action/single-action mode, meaning the first shot is a longer, heavier double-action pull, followed by crisp single-action shots. The ambidextrous decocker/manual safety allows for safe carrying with a round in the chamber and the hammer down. These pistols often come with a history of police service, indicating they’ve been maintained, even if they show external signs of use. They are known for their ability to handle a wide range of 9mm ammunition types without issue.
