Design and materials

The STANDARD CS follows a traditional roll-over ejection port and double wide slant serration on the slide for confident racking under stress. Exposed parts are machined from SAE 4140 high-grade steel with a matte chrome finish, while critical internal parts and sights use a Parkerized finish to reduce glare and increase durability. The double diamond checkered wood grips and a sculpted beavertail grip safety support a positive purchase and classic 1911-style feel.

Controls and ergonomics

Key control features include an ambidextrous safety lock, skeletonized hammer, and a smooth, angled low-profile rear sight designed to be snag-free during holstering or quick draws. The factory trigger is tuned to a crisp 4 to 6 lb pull, offering a balance between safety and accurate shot release. For more details, View product details and pricing.

Shooting performance and applications

The 9mm chambering with a 5″ barrel yields a favorable combination of manageable recoil, magazine capacity potential (depending on magazines used), and terminal performance suitable for defensive carry or duty use with appropriate load selection. The longer barrel improves sight radius and velocity versus compact designs, making this pistol a strong choice for both defensive drills and precision work on the range.
