Overview

Built for straightforward defensive use, this semi-automatic pistol focuses on practical handling and repeatable operation rather than extra features. The updated trigger design is intended to provide a more consistent pull, while the slide serrations are there to support easier manipulation during reloads and other routine handling. It also stays compatible with existing SD accessories, which can simplify setup for shooters who already use holsters, lights, or lasers in the SD line. With no manual safety and one 14-round magazine included, it suits hunters and outdoorsmen looking for a simple, utilitarian sidearm for range work or personal protection.
