Analysis

This .40 S&W striker-fired pistol offers a solid option for shooters seeking a reliable duty or self-defense firearm. Its accuracy is commendable, delivering consistent performance at typical engagement distances, while the ergonomic grip design accommodates a variety of hand sizes with customizable backstraps for improved control. Reliability is a key asset, with the firearm functioning well across a range of ammunition types and conditions. The trigger pull, averaging around 5.5 to 6 pounds, provides a predictable break, though some may find it slightly spongy. Felt recoil is manageable for most users, though it can be sharp due to the potent caliber. On the downside, maintenance can be somewhat involved, requiring attention to detail during disassembly. Additionally, sourcing replacement parts may pose challenges for some owners. Overall, it’s a capable choice, though not without minor limitations for certain users.
