Between a time-tested company reputation that’s over 150 years strong and the classic J-Frame design, there’s plenty going for our very first Gun of the Week: The Smith & Wesson M&P 340.

This lightweight, five-shot, double-action-only revolver is perfect for concealment and comes with an internal hammer that’ll keep it from catching on the draw. It’s chambered in .38 Special +P and the heavier .357 Mag., providing shooters with some options when planning their personal defense.

Those traits were enough to make the M&P 340 the personal carry gun of one Mark Keefe. You may have heard of him: Noted gun geek, American Rifleman Editor-in-Chief and a guy that’s handled quite a few firearms in his life—and this is the one that he’s selected to be at his side.

Smith & Wesson has succeeded in helping to protect citizens around the world since 1852, and beauties like the M&P 340 leave no doubts as to how or why.
