Critical dimensions of this classic pistol’s chassis determine compatibility with various components, affecting functionality, reliability, and accuracy. These specifications dictate slide-to-frame fit, influencing how the pistol cycles and performs. For instance, the distance between the rails, the locking lug recesses, and the ejection port dimensions are crucial for proper operation.
Accurate chassis dimensions are paramount for builders and gunsmiths undertaking custom work, repairs, or modifications. Understanding these tolerances ensures a precisely fitted and functioning firearm. Historically, variations have existed among manufacturers, making a thorough understanding of these details essential for proper parts selection and fitting. This knowledge also allows for informed decisions when diagnosing malfunctions or performance issues.
