Analysis

This double-stack pistol in .40 S&W caliber offers notable precision, thanks to its well-crafted barrel and tight tolerances, making it a strong choice for competitive shooting or range use. The ergonomic grip design accommodates a variety of hand sizes, providing a secure hold during extended sessions. Reliability is a key asset, with consistent performance across high round counts under proper care. The trigger pull is crisp, averaging around 4.5 pounds, which aids in maintaining control during rapid fire. Felt recoil is moderate for the caliber, manageable with practice, though some may find it sharper compared to similar models. On the downside, maintenance can be demanding, requiring meticulous cleaning to prevent wear on critical components. Parts availability may pose challenges, potentially delaying repairs. Additionally, the weight might deter users seeking a lighter carry option, limiting its appeal for everyday use.
