The Smith & Wesson Model 315 Night Guard is a compact K-frame revolver chambered in .38 Special +P and built around a lightweight scandium alloy frame with a stainless steel cylinder. It features a 2.5 inch barrel, matte black finish, and Pachmayr Compac rubber grips. The sight system consists of an XS tritium front sight paired with a fixed rear sight, providing a durable and highly visible arrangement.

The Night Guard series was introduced as a line of defensive revolvers combining lightweight alloy frames, tritium front sights, and short carry oriented barrel lengths. The Model 315 represents the K-frame variant of the series, maintaining the traditional six shot capacity of the platform while reducing overall weight compared to steel framed revolvers. The combination of scandium alloy construction and compact dimensions makes it a lighter alternative to traditional K-frame defensive revolvers while retaining the familiar double action/single action trigger system. Original case included.
