Ruger 90638 Security-9 Compact 9mm Pistol 10rd Steel Black Oxide

The Ruger Security-9 Compact delivers reliable performance and enhanced ergonomics in a striker-fired platform designed for concealed carry and personal defense. This 9mm pistol combines proven Ruger engineering with modern features that address common concerns about grip comfort and trigger performance in compact handguns.

What Makes This Different

The Security-9 Compact features Ruger's Secure Action fire-control system, which eliminates the need for a manual safety while providing consistent trigger performance. The grip frame incorporates aggressive texturing and interchangeable backstraps to accommodate different hand sizes. Unlike many compact pistols that sacrifice shootability for concealability, this model maintains a full grip length while reducing overall dimensions.

Key Features

• Secure Action striker-fired system with integrated trigger safety
• 10-round flush-fit magazine capacity with extended magazine compatibility
• Black oxide finish on alloy steel slide and barrel for corrosion resistance
• Three interchangeable grip backstraps (S, M, L) for custom fit
• Picatinny rail for tactical light or laser attachment
• Drift-adjustable 3-dot sights with white outlines
• Reversible magazine release for ambidextrous operation

Field testing demonstrates consistent accuracy with various 9mm ammunition weights, from 115-grain to 147-grain loads. The 3.42-inch barrel length provides adequate velocity for defensive ammunition expansion while maintaining compact dimensions suitable for concealed carry. Weather resistance testing shows reliable function in temperature ranges from -20°F to 140°F, with the black oxide finish providing superior corrosion protection compared to standard blued finishes.
