Key Features
- Compact, Concealable Frame — Why it matters: The shorter grip and 3.7-inch barrel make this pistol easy to hide under a light jacket or IWB holster, giving you everyday carry confidence without printing.
- Aggressive Grip Texturing — Why it matters: You’ll maintain a solid hold during rapid fire or in wet conditions, reducing the chance of your hand slipping when you need control most.
- Interchangeable Backstraps — Why it matters: Fit the grip to your hand size for a natural point of aim, which helps new shooters build accuracy faster and keeps experienced hands comfortable all day.
- Full Ambidextrous Controls — Why it matters: Left-handed shooters can operate the slide stop and magazine release without changing their grip, making this pistol a true family-friendly choice.
- Two 12-Round Magazines Included — Why it matters: You get a spare magazine right out of the box, so range sessions and carry rotations start immediately without extra purchases.
Who It’s For
